1993 FORD MONDEO battery location

15Coolant hydrometers are available at
most automotive accessory shops. If the
specific gravity of a sample taken from the
expansion tank (when the engine is switched
off and fully cooled down) is less than that
specified, the coolant mixture strength has
fallen below the minimum. If this is found,
either the coolant strength must be restored
by adding neat antifreeze to Ford’s
specification (if that is what is in the system)
or by draining and flushing the system, then
refilling it with fresh coolant mixture of the
correct ratio (if any other type of antifreeze is
being used).
16When checking the coolant level, always
note its condition; it should be relatively clear.
If it is brown or rust-coloured, the system
should be drained, flushed and refilled. If
antifreeze has been used which does not
meet Ford’s specification, its corrosion
inhibitors will lose their effectiveness with
time; such coolant must be renewed regularly,
even if it appears to be in good condition,
usually at the intervals suggested at the
beginning of Section 2 of this Chapter.
Windscreen/tailgate and
headlight washer fluid
17Fluid for the windscreen/tailgate washer
system (and where applicable the headlight
washer system) is stored in a plastic reservoir,
which is located at the right front corner of the
engine compartment. In milder climates, plain
water can be used to top-up the reservoir, but
the reservoir should be kept no more than
two-thirds full, to allow for expansion should
the water freeze. In colder climates, the use of
a specially-formulated windscreen washer
fluid, available at your dealer or any car
accessory shop, will help lower the freezing
point of the fluid (see illustration). Do notuse
regular (engine) antifreeze - it will damage the
vehicle’s paintwork.
Battery electrolyte
18On models not equipped with a sealed
battery (see Section 9), check the electrolyte
level of all six battery cells. The level must be
approximately 10 mm above the plates; this
may be shown by maximum and minimum
level lines marked on the battery’s casing (seeillustration). If the level is low, use a coin to
release the filler/vent cap, and add distilled
water. Install and securely retighten the cap.
Caution: Overfilling the cells may
cause electrolyte to spill over
during periods of heavy charging,
causing corrosion or damage.
Refer also to the warning at the beginning
of Section 9.
Brake fluid
19The brake fluid reservoir is located on the
top of the brake master cylinder, which is
attached to the front of the vacuum servo unit.
The “MAX” and “MIN” marks are indicated on
the side of the translucent reservoir, and the
fluid level should be maintained between
these marks at all times (see illustration).
20The brake fluid inside the reservoir is
readily visible. With the vehicle on level
ground, the level should normally be on or just
below the “MAX” mark.
21Progressive wear of the brake pads and
brake shoe linings causes the level of the
brake fluid to gradually fall; however, when
the brake pads are renewed, the original level
of the fluid is restored. It is not therefore
necessary to top-up the level to compensate
for this minimal drop, but the level must never
be allowed to fall below the minimum mark.
22If topping-up is necessary, first wipe the
area around the filler cap with a clean rag
before removing the cap. When adding fluid,
pour it carefully into the reservoir, to avoid
spilling it on surrounding painted surfaces
(see illustration). Be sure to use only the
specified hydraulic fluid (see “Lubricants,
fluids and capacities”at the start of this
Chapter) since mixing different types of fluid
can cause damage to the system.
Warning: Brake hydraulic fluid
can harm your eyes and damage
painted surfaces, so use extreme
caution when handling and
pouring it. Wash off spills immediately with
plenty of water. Do not use fluid that has
been standing open for some time, as it
absorbs moisture from the air. Excessmoisture can cause corrosion and a
dangerous loss of braking effectiveness.
23When adding fluid, it is a good idea to
inspect the reservoir for contamination. The
system should be drained and refilled if
deposits, dirt particles or contamination are
seen in the fluid.
24After filling the reservoir to the correct
level, make sure that the cap is refitted
securely, to avoid leaks and the entry of
foreign matter.
25If the reservoir requires repeated
replenishing to maintain the correct level, this
is an indication of an hydraulic leak
somewhere in the system, which should be
investigated immediately.
Power steering fluid
26See Section 5 of this Chapter.
1Periodic inspection of the tyres may spare
you from the inconvenience of being stranded
with a flat tyre. It can also provide you with
vital information regarding possible problems
in the steering and suspension systems
before major damage occurs.
2The original tyres on this vehicle are
equipped with tread wear indicator (TWI)
bands, which will appear when the tread
depth reaches approximately 1.6 mm. Most
tyres have a mark around the tyre at regular
intervals to indicate the location of the tread

5Refitting is the reverse of the removal
procedure. Ensure that the element and cover
are securely seated, so that unfiltered air
cannot enter the engine.
1The Positive Crankcase Ventilation (PCV)
system components are located at the front of
the engine, underneath the exhaust manifold
and air intake resonator. Refer to Chapter 6
for further information.
2Check that all components of the system
are securely fastened, correctly routed (with
no kinks or sharp bends to restrict flow) and in
sound condition; renew any worn or damaged
components.
3If oil leakage is noted, disconnect the
various hoses and pipes, and check that all
are clear and unblocked. Remove the air
cleaner assembly cover, air mass meter and
resonator, then check that the hose from the
cylinder head cover to the air cleaner housing
is clear and undamaged. Disconnect the
rubber T-piece both from the union on the
inlet manifold left-hand end, and from the
metal crankcase breather pipe under the
ignition coil. Connect a spare, clean, length of
hose to the breather pipe. Suck on the end of
the hose, then blow through it - little or norestriction to airflow should be felt in either
direction. A similar test can be applied to
check that the inlet manifold passages are
clear - air should be heard hissing out of the
plenum chamber mouth as you blow.
4The PCV valve is designed to allow gases
to flow out of the crankcase only, so that a
depression is created in the crankcase under
most operating conditions, particularly at idle.
Therefore, if either the oil separator or the PCV
valve are thought to be blocked, they must be
renewed (see Chapter 6). In such a case,
however, there is nothing to be lost by
attempting to flush out the blockage using a
suitable solvent. The PCV valve should rattle
when shaken.
5While the air filter element is removed (see
Section 29), wipe out the housing, and
withdraw the small foam filter from its location
in the rear right-hand corner of the housing
(see illustration). If the foam is badly clogged
with dirt or oil, it must be cleaned by soaking it
in a suitable solvent, and allowed to dry
before being refitted.
Spark plug check and renewal
1It is vital for the correct running, full
performance and proper economy of the
engine that the spark plugs perform with
maximum efficiency. The most important
factor in ensuring this is that the plugs fitted
are appropriate for the engine. The suitable
type is given in the Specifications Section at
the beginning of this Chapter, on the Vehicle
Emissions Control Information (VECI) label
located on the underside of the bonnet (only
on models sold in some areas) or in the
vehicle’s Owner’s Handbook. If these sources
specify different plugs, purchase the spark
plug type specified on the VECI label (where
appropriate), as that information is provided
specifically for your engine. If this type is used
and the engine is in good condition, the spark
plugs should not need attention between
scheduled renewal intervals. Spark plug
cleaning is rarely necessary, and should notbe attempted unless specialised equipment is
available, as damage can easily be caused to
the firing ends.
2Spark plug removal and refitting requires a
spark plug socket, with an extension which
can be turned by a ratchet handle or similar.
This socket is lined with a rubber sleeve, to
protect the porcelain insulator of the spark
plug, and to hold the plug while you insert it
into the spark plug hole. You will also need a
wire-type feeler gauge, to check and adjust
the spark plug electrode gap, and a torque
wrench to tighten the new plugs to the
specified torque (see illustration).
3To remove the spark plugs, first open the
bonnet; the plugs are easily reached at the
top of the engine. Note how the spark plug
(HT) leads are routed and secured by clips
along the channel in the cylinder head cover.

specifications were available from Ford, but a
typical reading would be in excess of 12 bars.
All cylinders should produce very similar
pressures; any difference greater than 10%
indicates the existence of a fault. Note that the
compression should build up quickly in a
healthy engine; low compression on the first
stroke, followed by gradually-increasing
pressure on successive strokes, indicates worn
piston rings. A low compression reading on the
first stroke, which does not build up during
successive strokes, indicates leaking valves or a
blown head gasket (a cracked head could also
be the cause). Deposits on the undersides of the
valve heads can also cause low compression.
8If the pressure in any cylinder is
considerably lower than the others, introduce
a teaspoonful of clean oil into that cylinder
through its spark plug hole, and repeat the
test.
9If the addition of oil temporarily improves
the compression pressure, this indicates that
bore or piston wear is responsible for the
pressure loss. No improvement suggests that
leaking or burnt valves, or a blown head
gasket, may be to blame.
10A low reading from two adjacent cylinders
is almost certainly due to the head gasket
having blown between them; the presence of
coolant in the engine oil will confirm this.
11If one cylinder is about 20 percent lower
than the others and the engine has a slightly
rough idle, a worn camshaft lobe or faulty
hydraulic tappet could be the cause.
12If the compression is unusually high, the
combustion chambers are probably coated
with carbon deposits. If this is the case, the
cylinder head should be removed and
decarbonised.
13On completion of the test, refit the spark
plugs, then reconnect the ignition system and
fuel pump.
General
1Top Dead Centre (TDC) is the highest point
in its travel up-and-down its cylinder bore
that each piston reaches as the crankshaftrotates. While each piston reaches TDC both
at the top of the compression stroke and
again at the top of the exhaust stroke, for the
purpose of timing the engine, TDC refers to
the piston position (usually No 1 piston) at the
top of its compression stroke.
2It is useful for several servicing procedures
to be able to position the engine at TDC.
3No 1 piston and cylinder are at the right-
hand (timing belt) end of the engine (right-
and left-hand are always quoted as seen from
the driver’s seat). Note that the crankshaft
rotates clockwise when viewed from the
right-hand side of the vehicle.
Locating TDC
4Remove all the spark plugs (Chapter 1).
5Disconnect both battery leads - see
Chapter 5, Section 1 - unless the starter
motor is to be used to turn the engine.
6Apply the handbrake and ensure that the
transmission is in neutral, then jack up the
front right-hand side of the vehicle and
support on an axle stand. Remove the
roadwheel.
7Remove the auxiliary drivebelt cover (see
Chapter 1) to expose the crankshaft pulley
and timing marks.
8It is best to rotate the crankshaft using a
spanner applied to the crankshaft pulley bolt;
however, it is possible also to use the starter
motor (switched on either by an assistant
using the ignition key, or by using a remote
starter switch) to bring the engine close to
TDC, then finish with a spanner. If the starter
is used, be sure to disconnect the battery
leads immediately it is no longer required.
9Note the two pairs of notches in the inner
and outer rims of the crankshaft pulley. In the
normal direction of crankshaft rotation
(clockwise, seen from the right-hand side of the
vehicle) the first pair of notches are irrelevant to
the vehicles covered in this manual, while the
second pair indicate TDC when aligned with
the rear edge of the raised mark on the sump.
Rotate the crankshaft clockwise until the
second pair of notches align with the edge of
the sump mark; use a straight edge extended
out from the sump if greater accuracy is
required (see illustrations).10Nos 1 and 4 cylinders are now at TDC,
one of them on the compression stroke.
Remove the oil filler cap; if No 4 cylinder
exhaust cam lobe is pointing to the rear of the
vehicle and slightly downwards, it is No 1
cylinder that is correctly positioned. If the
lobe is pointing horizontally forwards, rotate
the crankshaft one full turn (360°) clockwise
until the pulley notches align again, and the
lobe is pointing to the rear and slightly down.
No 1 cylinder will then be at TDC on the
compression stroke.
11Once No 1 cylinder has been positioned
at TDC on the compression stroke, TDC for
any of the other cylinders can then be located
by rotating the crankshaft clockwise 180° at a
time and following the firing order (see
Specifications).
12An alternative method of locating TDC is
to remove the cylinder head cover (see
Section 5) and to rotate the crankshaft
(clockwise, as described in paragraph 8
above) until the inlet valves for the cylinder
concerned have opened and just closed
again. Insert a length of wooden dowel
(approximately 150 mm/6 in long) or similar
into the spark plug hole until it rests on the
piston crown, and slowly further rotate the
crankshaft (taking care not to allow the dowel
to be trapped in the cylinder) until the dowel
stops rising - the piston is now at the top of
its compression stroke, and the dowel can be
removed.
13There is a “dead” area around TDC (as
the piston stops rising, pauses and then
begins to descend) which makes difficult the
exact location of TDC by this method; if
accuracy is required, either establish carefully
the exact mid-point of the dead area, or refer
to the timing marks (paragraph 9 above).

3Remove the timing belt upper cover (see
Section 9).
4Disconnect the crankcase breather hose
from the cylinder head cover union (see
illustration).
5Unplug the HT leads from the spark plugs
and withdraw them, unclipping the leads from
the cover.
6Working progressively, unscrew the
cylinder head cover retaining bolts, noting the
spacer sleeve and rubber seal at each, then
withdraw the cover (see illustration).
7Discard the cover gasket; this mustbe
renewed whenever it is disturbed. Check that
the sealing faces are undamaged, and that
the rubber seal at each retaining bolt is
serviceable; renew any worn or damaged
seals.
8On refitting, clean the cover and cylinder
head gasket faces carefully, then fit a new
gasket to the cover, ensuring that it locates
correctly in the cover grooves (see
illustration).
9Refit the cover to the cylinder head, then
insert the rubber seal and spacer sleeve at
each bolt location (see illustration). Start all
bolts finger-tight, ensuring that the gasket
remains seated in its groove.
10Working in a diagonal sequence from the
centre outwards, and in two stages (see
Specifications), tighten the cover bolts to the
specified torque wrench setting.
11Refit the HT leads, clipping them into
place so that they are correctly routed; each
is numbered, and can also be identified by
the numbering on its respective coil terminal.
12Reconnect the crankcase breather hose,
and refit the timing belt upper cover.
Reconnect and adjust the accelerator cable,
then refit the air cleaner assembly cover with
the air mass meter, the resonator and the
plenum chamber (see Chapter 4).
Warning: Petrol is extremely
flammable, so take extra
precautions when disconnecting
any part of the fuel system. Don’t smoke,
or allow naked flames or bare light bulbs in
or near the work area. Don’t work in a
garage where a natural gas appliance
(such as a clothes dryer or water heater) is
installed. If you spill petrol on your skin,
rinse it off immediately. Have a fire
extinguisher rated for petrol fires handy,
and know how to use it.
Removal
1Park the vehicle on firm, level ground,
apply the handbrake firmly, and slacken the
nuts securing the right-hand front roadwheel.
2Relieve the fuel system pressure (see
Chapter 4).3Disconnect the battery negative (earth) lead
- see Chapter 5, Section 1.
4Unplugging the two electrical connectors
and disconnecting the vacuum hose (where
fitted), remove the air cleaner assembly cover
with the air mass meter, the resonator and the
plenum chamber (see Chapter 4).
5Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -
where fitted, disconnect also the cruise
control actuator cable (see Chapter 12).
6Disconnect the crankcase breather hose
from the cylinder head cover union.
7Unbolt the upper part of the exhaust
manifold heat shield; unclip the coolant hose
to allow it to be withdrawn. Slacken the
sleeve nut securing the EGR pipe to the
manifold, remove the two screws securing
the pipe to the ignition coil bracket, then
unscrew the sleeve nut securing the pipe to
the EGR valve - see Chapter 6 for full details if
required.
8Remove the two screws securing the wiring
“rail” to the top of the manifold - this is simply
so that it can be moved as required to reach
the manifold bolts. Unplug their electrical
connectors to disconnect the camshaft
position sensor and the coolant temperature
sensor, then unclip the wiring from the ignition
coil bracket, and secure it to the manifold.
9Remove the three screws securing the
wiring “rail” to the rear of the manifold.
Releasing its wire clip, unplug the large
electrical connector (next to the fuel pressure
regulator) to disconnect the wiring of themanifold components from the engine wiring
loom.
10Marking or labelling them as they are
unplugged, disconnect the vacuum hoses as
follows:
(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator).
(b) One from the union on the manifold’s left-
hand end.
(c) The braking system vacuum servo unit
hose (see Chapter 9 for details).
(d) One from the Exhaust Gas Recirculation
(EGR) valve.
11Equalise the pressure in the fuel tank by
removing the filler cap, then undo the fuel
feed and return lines connecting the engine to

23If using Ford’s recommended procedure,
fit new oil seals to the camshafts as
described in paragraph 5 of Section 12.
24Using the marks and notes made on
dismantling to ensure that each is refitted to
its original camshaft, refit the toothed pulleys
to the camshafts, tightening the retaining
bolts loosely (see illustration). Slip the timing
belt back onto the pulleys (refer to para-
graph 21 of Section 10) and tighten the bolts
securely - use the forked holding tool
described in paragraph 18 of Section 10.
25The remainder of the reassembly
procedure, including checking the camshaft
alignment (valve timing) and setting the timing
belt tension, is as described in paragraphs 17
to 27 of Section 10.
Removal
Note:The following text assumes that the
cylinder head will be removed with both inlet
and exhaust manifolds attached; this
simplifies the procedure, but makes it a bulky
and heavy assembly to handle - an engine
hoist will be required, to prevent the risk of
injury, and to prevent damage to any delicate
components as the assembly is removed and
refitted. If it is wished first to remove the
manifolds, proceed as described in Sections
6 and 7 of this Chapter; amend the following
procedure accordingly.1Relieve the fuel system pressure (see
Chapter 4).
2With the vehicle parked on firm level
ground, open the bonnet and disconnect the
battery negative (earth) lead - see Chapter 5,
Section 1.
3Whenever you disconnect any vacuum
lines, coolant and emissions hoses, wiring
loom connectors, earth straps and fuel lines
as part of the following procedure, always
label them clearly, so that they can be
correctly reassembled.
4Unplugging the two electrical connectors,
disconnecting the vacuum hose (where fitted)
and disconnecting the crankcase breather
hose from the cylinder head cover, remove
the complete air cleaner assembly with the air
mass meter, the resonator and the plenum
chamber (see Chapter 4).
5Equalise the pressure in the fuel tank by
removing the filler cap, then undo the fuel
feed and return lines connecting the engine to
the chassis (see Chapter 4). Plug or cap all
open fittings.
6Disconnect the accelerator cable from the
throttle linkage as described in Chapter 4 -where fitted, disconnect also the cruise control
actuator cable (see Chapter 12). Secure the
cable(s) clear of the engine/transmission.
7Unbolt the power steering high-pressure
pipe from the cylinder head rear support
plate/engine lifting eye, and from the front
support plate/pump bracket. Releasing its
wire clip, unplug the power steering pressure
switch electrical connector, then unbolt the
earth lead from the cylinder head rear support
plate/engine lifting eye.
8Remove the three screws securing the
wiring “rail” to the rear of the manifold.
Releasing its wire clip, unplug the large
electrical connector (next to the fuel pressure
regulator) to disconnect the engine wiring from
the main loom (see illustration). Unplug the
electrical connectors on each side of the
ignition coil, and the single connector from
beneath the front of the thermostat housing, to
disconnect the coil and coolant temperature
gauge sender wiring (see illustration).
9Marking or labelling them as they are
unplugged, disconnect the vacuum hoses as
follows:
(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose (see Chapter 9 for details).
(d) Disconnect all vacuum hoses from the
Exhaust Gas Recirculation system
components - one from the EGR valve
and two from the EGR pipe. (Note that
these last two are of different sizes, as are
their pipe stubs, so that they can only be
connected the correct way round.)
10Unbolt both parts of the exhaust manifold
heat shield; unclip the coolant hose to allow the
upper part to be withdrawn. Either remove the
dipstick and tube, or swing them out of the way.
11Unscrew the single bolt securing the
pulse-air filter housing to the engine/
transmission front mounting bracket, then
disconnect its vacuum hose.
12Drain the cooling system (see Chapter 1).

safely and with relative ease, and which may
have to be hired or borrowed, includes (in
addition to the engine hoist) a heavy-duty trolley
jack, a strong pair of axle stands, some wooden
blocks, and an engine dolly (a low, wheeled
platform capable of taking the weight of the
engine/transmission, so that it can be moved
easily when on the ground). A complete set of
spanners and sockets (as described in the front
of this manual) will obviously be needed,
together with plenty of rags and cleaning
solvent for mopping-up spilled oil, coolant and
fuel. If the hoist is to be hired, make sure that
you arrange for it in advance, and perform all of
the operations possible without it beforehand.
This will save you money and time.
Plan for the vehicle to be out of use for
quite a while. A machine shop will be required
to perform some of the work which the do-it-
yourselfer can’t accomplish without special
equipment. These establishments often have
a busy schedule, so it would be a good idea
to consult them before removing the engine,
to accurately estimate the amount of time
required to rebuild or repair components that
may need work.
Always be extremely careful when removing
and installing the engine/transmission.
Serious injury can result from careless
actions. By planning ahead and taking your
time, the job (although a major task) can be
accomplished successfully.
Warning: Petrol is extremely
flammable, so take extra
precautions when disconnecting
any part of the fuel system. Don’t
smoke, or allow naked flames or bare light
bulbs in or near the work area, and don’t
work in a garage where a natural gas
appliance (such as a clothes dryer or water
heater) is installed. If you spill petrol on
your skin, rinse it off immediately. Have a
fire extinguisher rated for petrol fires
handy, and know how to use it.Note: Read through the entire Section, as well
as reading the advice in the preceding Section,
before beginning this procedure. The engine
and transmission are removed as a unit,
lowered to the ground and removed from
underneath, then separated outside the vehicle.

(a) One from the rear of the throttle housing
(only the one hose - there is no need to
disconnect the second hose running to
the fuel pressure regulator) (see
illustration).
(b) One from the union on the inlet manifold’s
left-hand end (see illustration).
(c) The braking system vacuum servo unit
hose - from the inlet manifold (see
Chapter 9 for details).
(d) Also disconnect the vacuum hoses from
the Exhaust Gas Recirculation system
components - one from the EGR valve,
two from the EGR pipe (note that these
last two are of different sizes, as are their
pipe stubs, so that they can only be
connected the correct way round).
(e) While you are there, trace the vacuum line
from the pulse-air filter housing over the
top of the transmission, and disconnect it
by pulling the plastic pipe out of the
rubber hose just beneath the bulkhead-
mounted pulse-air solenoid valve (see
illustration).
(f) Secure all these hoses so that they won’t
get damaged as the engine/transmission
is removed.
11Unbolt the engine/transmission-to-body
earth lead from the transmission’s top surface
(see illustration). Disconnect the speed-
ometer drive cable (see Chapter 12) and
secure it clear of the engine/transmission.
12Where the vehicle is fitted with manual
transmission, disconnect the clutch cable (seeChapter 8). Where automatic transmission is
fitted, disconnect the selector cable (see
Chapter 7, Part B). Secure the cable clear of
the engine/transmission.
13Marking or labelling all components as
they are disconnected (see paragraph 5
above), disconnect the engine wiring loom
from the body as follows:
(a) Starting at the left-hand side of the engine
compartment, release and unplug the
three large electrical connectors clipped
to the suspension mounting - note the
wire clips fitted to some connectors (see
illustration).
(b) Disconnect and/or release the battery-to-
starter motor wiring, noting the single
connector which must be unplugged.
(c) Unplug the electrical connector(s) to
disconnect the vehicle speed sensor,
oxygen sensor and, where fitted, the oil
level sensor wiring - unclip the connectors
to release the wiring where necessary.
(d) Work along the loom to the bulkhead,
unclipping the loom and unplugging the
various bulkhead-mounted components
connected into it, until you reach the
right-hand side of the engine
compartment (see illustration).
(e) Carefully prise the power steering fluid
reservoir upwards out of its clip on the
suspension mounting, then unscrew the
ECU connector’s retaining bolt and
unplug the connector (see illustration).
(f) Unbolt the earth lead from the right-hand

sender’s electrical connector, and use a
jumper wire to connect the white/red wire to a
clean earth point (bare metal) on the engine.
Switch on the ignition without starting the
engine. If the gauge now indicates Hot, renew
the sender.
5If the gauge still does not work, the circuit
may be open, or the gauge may be faulty. See
Chapter 12 for additional information.
Removal
6Unbolt the resonator support bracket from
the engine compartment front crossmember.
Slacken the two clamp screws securing the
resonator to the air mass meter and plenum
chamber hoses, then swing the resonator up
clear of the thermostat housing (see Chap-
ter 4).
7Drain the cooling system (see Chapter 1).
8Disconnect the expansion tank coolant
hose and the radiator top hose from the
thermostat housing’s water outlet, then
disconnect the metal coolant pipe/hose from
the thermostat.
9Unplug the electrical connector from the
sender (see illustration).
10Unscrew the sender and withdraw it.
Refitting
11Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sender’s threads.
Screw in the sender and tighten it to the
specified torque wrench setting, and plug in
its electrical connector.
12Reconnect the hoses and refit the
resonator, top-up the cooling system (see
Chapter 1) and run the engine. Check for
leaks and proper gauge operation.
Coolant temperature sensor
Testing
13Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
14Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
15Unplug the electrical connector from the
sensor (see illustration).
16Using an ohmmeter, measure the
resistance between the sensor terminals.
Depending on the temperature of the sensor
tip, the resistance measured will vary, but
should be within the broad limits given in the
Specifications Section of this Chapter. If the
sensor’s temperature is varied - by removing
it (see below) and placing it in a freezer for a
while, or by warming it gently - its resistance
should alter accordingly.
17If the results obtained show the sensor to
be faulty, renew it.
18On completion, plug in the connector and
refit the resonator.
Removal
19Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
20Unbolt the resonator support bracket
from the engine compartment front
crossmember. Slacken the two clamp screws
securing the resonator to the air mass meter
and plenum chamber hoses, then swing the
resonator up clear of the thermostat housing
(see Chapter 4).
21With the engine completely cool, remove
the expansion tank filler cap to release any
pressure, then refit the cap. Provided you
work swiftly and plug the opening as soon as
the sensor is unscrewed, coolant loss will thus
be minimised; this will avoid the draining of
the complete cooling system which would
otherwise be necessary (see Chapter 1).
22Unplug the electrical connector from the
sensor.
23Unscrew the sensor and withdraw it. If the
cooling system has not been drained, plug the
opening as quickly as possible.
Refitting
24Clean as thoroughly as possible the
opening in the thermostat housing, then apply
a light coat of sealant to the sensor’s threads.
Remove the material used to plug the sensor
hole (where applicable), and quickly install the
sensor to prevent coolant loss. Tighten the
sensor to the specified torque wrench setting,
and plug in its electrical connector.
25Refit the resonator, top-up the cooling
system (see Chapter 1) and run the engine,
checking for leaks.
Coolant low level switch
Testing
26The switch is a reed-type unit mounted in
the bottom of the cooling system expansion
tank, activated by a magnetic float. If the
coolant level falls to the “MIN” level or less,
the appropriate bulb lights in the warning
display.
27If the bulb fails to light during the 5-
second bulb test, check the bulb, and renew if
necessary as described in Chapter 12.
28To check the switch itself, unplug its
electrical connector, and use an ohmmeter to
measure the resistance across the switchterminals. With the float up, a resistance of
90 ohms should be measured; when it is
down, the resistance should increase to
approximately 150 kilohms.
29If the results obtained from the check are
significantly different from those expected,
the switch is faulty, and must be renewed.
30If the switch and bulb are proven to be
sound, the fault must be in the wiring or in the
auxiliary warning control assembly (see
Chapter 12).
Removal
31Disconnect the battery negative (earth)
lead (see Chapter 5, Section 1).
32Remove the expansion tank (see Sec-
tion 7).
33Unplug the switch electrical connector.
34Release the switch by twisting its retainer
anti-clockwise, then withdraw it.
Refitting
35Refitting is the reverse of the removal
procedure. Refill the cooling system (see
Chapter 1). Start the engine, and check for
coolant leaks when it is fully warmed-up.
Note:Refer to the warnings given in Section 1
of this Chapter before starting work.
Radiator
Removal
Note:If leakage is the reason for removing the
radiator, bear in mind that minor leaks can
often be cured using a radiator sealant with
the radiator in situ.
1Remove the radiator fan and shroud
assembly (see Section 5).
2Disconnect the bottom hose from the
radiator.
3If the vehicle has automatic transmission,
disconnect the fluid cooler lines, and plug the
lines and fittings.
4If the vehicle has air conditioning, unscrew
the condenser mounting nuts or bolts, detach
the condenser from the radiator, and tie it to
the engine compartment front crossmember.
