3 Engine oil and filter renewal
1
1Make sure that you have all the necessary
tools before you begin this procedure (see
illustration) . You should also have plenty of
rags or newspapers handy, for mopping up
any spills.
2 To avoid any possibility of scalding, and to
protect yourself from possible skin irritants
and other harmful contaminants in used
engine oils, it is advisable to wear gloves
when carrying out this work. 3
Access to the underside of the vehicle is
greatly improved if the vehicle can be lifted on a
hoist, driven onto ramps, or supported by axle
stands (see “Jacking and Vehicle Support” ).
Warning: Do not work under a
vehicle which is supported only
by an hydraulic or scissors-type
jack, or by bricks, blocks of
wood, etc. 4
If this is your first oil change, get under the
vehicle and familiarise yourself with the
position of the engine oil drain plug location in
the sump. The engine and exhaust
components will be warm during the actual
work, so try to anticipate any potential
problems while the engine and accessories
are cool.
5 The oil should preferably be changed when
the engine is still fully warmed-up to normal
operating temperature, just after a run (the
needle on the temperature gauge should be in
the “Normal” sector of the gauge); warm oil
and sludge will flow out more easily. Park the
vehicle on firm, level ground, apply the
handbrake firmly, then select 1st or reverse
gear (manual transmission) or the “P” position
(automatic transmission). Open the bonnet
and remove the engine oil filler cap from the
cylinder head cover, then remove the oil level
dipstick from its tube (see “Weekly Checks”).
6 Raise the front of the vehicle, and support it
securely on axle stands (see “Jacking and
Vehicle Support” ). Remove the front right-
hand roadwheel to provide access to the oil
1 Introduction
This Chapter is designed to help the home
mechanic maintain his/her vehicle for safety,
economy, long life and peak performance.
This Chapter contains a master
maintenance schedule, followed by Sections
dealing specifically with each task in the
schedule. Visual checks, adjustments,
component renewal and other helpful items
are included. Refer to the accompanying
illustrations of the engine compartment and
the underside of the vehicle for the locations
of the various components.
Servicing your vehicle in accordance with
the mileage/time maintenance schedule and
the following Sections will provide a planned
maintenance programme, which should result
in a long and reliable service life. This is a
comprehensive plan, so maintaining some
items but not others at the specified service
intervals will not produce the same results. As you service your vehicle, you will
discover that many of the procedures can -
and should - be grouped together, because of
the particular procedure being performed, or
because of the close proximity of two
otherwise-unrelated components to one
another. For example, if the vehicle is raised
for any reason, the exhaust should be
inspected at the same time as the suspension
and steering components.
The first step of this maintenance
programme is to prepare yourself before the
actual work begins. Read through all the Sections relevant to the work to be carried
out, then make a list and gather together all
the parts and tools required. If a problem is
encountered, seek advice from a parts
specialist or a dealer service department.
2 Intensive maintenance
1
If, from the time the vehicle is new, the
routine maintenance schedule is followed
closely, and frequent checks are made of fluid
levels and high-wear items, as suggested
throughout this manual, the engine will be
kept in relatively good running condition, and
the need for additional work will be minimised.
2 It is possible that there will be some times
when the engine is running poorly due to the
lack of regular maintenance. This is even more
likely if a used vehicle, which has not received
regular and frequent maintenance checks, is
purchased. In such cases, additional work
may need to be carried out, outside of the
regular maintenance intervals.
3 If engine wear is suspected, a compression
test (refer to Part A, B or C of Chapter 2) will
provide valuable information regarding the
overall performance of the main internal
components. Such a test can be used as a
basis to decide on the extent of the work to
be carried out. If, for example, a compression
test indicates serious internal engine wear,
conventional maintenance as described in this
Chapter will not greatly improve the
performance of the engine, and may prove a waste of time and money, unless extensive
overhaul work (Chapter 2D) is carried out first.
4
The following series of operations are those
often required to improve the performance of
a generally poor-running engine:
Primary operations
a) Clean, inspect and test the battery (See
“Weekly Checks”).
b) Check all the engine-related fluids (See
“Weekly Checks”).
c) Check the condition of the auxiliary drivebelt (Section 4).
d) Check and if necessary adjust the valve
clearances on HCS engines (Section 7).
e) Renew the spark plugs and clean and inspect the HT leads (Section 21).
f) Check the condition of the air cleaner filter element and renew if necessary
(Section 24).
g) Check and if necessary adjust the idle speed and mixture settings - where
applicable (Section 9).
h) Renew the fuel filter - fuel injection models (Section 30).
i) Check the condition of all hoses, and check for fluid leaks (Section 5).
5 If the above operations do not prove fully
effective, carry out the following operations:
Secondary operations
All the items listed under “Primary
operations”, plus the following: a) Check the charging system (Chapter 5A).
b) Check the ignition system (Chapter 5B).
c) Check the fuel system (Chapter 4A, 4B,
4C and 4D).
e) Renew the ignition HT leads (Section 21).

gasket onto the top face of the cylinder block
and over the dowels. Ensure that it is correctly
aligned with the coolant passages and
oilways (see illustration) .
26 Lower the cylinder head carefully into
position, then insert the retaining bolts and
hand-tighten them.
27 Tightening of the cylinder head bolts must
done in three stages, and in the correct
sequence (see illustration) . First tighten all of
the bolts in the sequence shown to the
Stage 1 torque setting (see illustration).
When all of the bolts are tightened to the
Stage 1 setting, further tighten each bolt (in
sequence) through the Stage 2 specified
angle of rotation. When the second stage
tightening is completed on all of the bolts,
further tighten them to the Stage 3 angle
setting (in sequence) to complete. Where
possible, use an angular torque setting gauge
attachment tool for accurate tightening of
stages two and three (see illustration).
28 Lubricate the pushrods with clean engine
oil, and then insert them into their original
locations in the engine.
29 Refit the rocker shaft assembly. As it is
fitted, ensure that the rocker adjuster screws
engage with their corresponding pushrods.
30 Refit the rocker shaft retaining bolts,
hand-tighten them and then tighten them
to the specified torque wrench setting. As
they are tightened, some of the rocker arms
will apply pressure to the ends of the valve
stems, and some of the rocker pedestals will
not initially be in contact with the cylinder head - these should pull down as the bolts are
tightened. If for any reason they do not, avoid
the temptation to overtighten in order to pull
them into position; loosen off the bolts, and
check the cause of the problem. It may be
that the rocker adjuster screws require
loosening off in order to allow the assembly to
be tightened down as required.
31
Adjust the valve clearances as described
in Section 5.
32 Refit the rocker cover as described in
Section 4.
33 The remainder of the refitting procedure is
a reversal of the removal process. Tighten all
fastenings to their specified torque setting
(where given). Refer to the appropriate Parts
of Chapter 4 for details on reconnecting the
fuel and exhaust system components. Ensure
that all coolant, fuel, vacuum and electrical
connections are securely made.
34 On completion, refill the cooling system
and top-up the engine oil (see Chapter 1 and
“Weekly Checks” ). When the engine is
restarted, check for any sign of fuel, oil and/or
coolant leakages from the various cylinder
head joints.
8 Crankshaft pulley -
removal and refitting
2
Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ). Remove
the right-hand front roadwheel.
3 Remove the auxiliary drivebelt as described
in Chapter 1.
4 Loosen off the crankshaft pulley retaining
bolt. To prevent the crankshaft from turning,
unbolt and remove the clutch housing cover
plate. Lock the starter ring gear on the
flywheel using a large screwdriver or similar
tool inserted through the cover plate aperture.
Alternatively, remove the starter motor
(Chapter 5A) and lock the ring gear through
the starter motor aperture. 5
Fully unscrew the crankshaft pulley bolt,
and withdraw the pulley from the front end of
the crankshaft. If it does not pull off by hand,
lever it free using a pair of suitable levers
positioned diagonally opposite each other
behind the pulley.
6 If required, the crankshaft front oil seal can
be renewed at this stage, as described in
Section 14.
Refitting
7 Refitting is a reversal of the removal
procedure ensuring that the pulley retaining
bolt is tightened to the specified torque
setting.
8 Refit the auxiliary drivebelt as described in
Chapter 1, and lower the vehicle to complete.
9 Timing chain cover -
removal and refitting
2
Removal
1 Remove the sump as described in Sec-
tion 11.
2 Remove the crankshaft pulley as described
in the previous Section.
3 A combined timing cover and water pump
gasket is fitted during production; if this is still
in position, it will be necessary to drain the
cooling system and remove the water pump
as described in Chapter 3. If the water pump
and/or the timing cover have been removed at
any time, the single gasket used originally will
have been replaced by an individual gasket
for each component, in which case the water
pump can remain in position.
4 Unscrew the retaining bolts, and carefully
prise free the timing chain cover.
5 Clean the mating faces of the timing chain
cover, and the engine.
6 If necessary, renew the crankshaft front oil
seal in the timing cover prior to refitting the
cover (see Section 14).

cover). Using a new gasket, fit the timing
chain cover, centring it with the aid of the
crankshaft pulley - lubricate the seal contact
surfaces beforehand. Refit and tighten the
retaining bolts but, where applicable, leave
out the timing cover bolt which also secures
the water pump at this stage.
8Where applicable, refit the water pump as
described in Chapter 3.
9 Refit the crankshaft pulley as described in
the previous Section.
10 Refit the sump as described in Section 11.
10Timing chain, sprockets and
tensioner - removal,
inspection and refitting
3
Removal
1 Remove the timing chain cover as
described in the previous Section.
2 Remove the oil slinger from the front face of
the crankshaft, noting its orientation (see
illustration) .
3 Retract the chain tensioner cam back
against its spring pressure, then slide the
chain tensioner arm from its pivot pin on the
front main bearing cap (see illustration).
4 Unbolt and remove the chain tensioner.
5 Bend back the lockplate tabs from the
camshaft sprocket bolts, then unscrew and
remove the bolts.
6 Withdraw the sprocket complete with the
timing chain.
Inspection
7 Examine the teeth on the timing sprockets
for any signs of excessive wear or damage.
8 The timing chain should always be renewed
during a major engine overhaul. Slack links
and pins are indicative of a worn chain.
Unless the chain is known to be relatively
new, it should be renewed.
9 Examine the rubber cushion on the
tensioner spring leaf. If grooved or
deteriorated, it must be renewed.
Refitting
10 Commence reassembly by bolting the
timing chain tensioner into position. Check
that the face of the tensioner cam is parallel
with the face of the cylinder block, ideally
using a dial gauge. The maximum permissible
error between the two measuring points is
0.2 mm. Release and turn the timing chain
tensioner as required to achieve this (if
necessary). Refer to the Specifications for the
correct tightening torque.
11 Turn the crankshaft so that the timing
mark on its sprocket is directly in line with the
centre of the camshaft sprocket mounting
flange.
12 Engage the camshaft sprocket with the
timing chain, then engage the chain around
the teeth of the crankshaft sprocket. Push the
camshaft sprocket onto its mounting flange,
and check that the sprocket retaining bolt
holes are in alignment (see illustration). Alsocheck that the timing marks of both sprockets
face each other. If required, turn the
camshaft/sprocket as required to achieve this.
It may also be necessary to remove the
camshaft from the chain in order to reposition
it in the required location in the chain to align
the timing marks. This is a “trial and error”
procedure, which must be continued until the
exact alignment of the bolt holes and the
timing marks is made
(see illustration).
13 Insert and tighten the camshaft sprocket
retaining bolts to the specified torque wrench
setting. Bend up the tabs of the new lockplate
to secure (see illustration) .
14 Retract the timing chain tensioner cam,
and then slide the tensioner arm onto its pivot
pin. Release the cam so that it bears on the
arm.
15 Refit the oil slinger to the front of the
crankshaft sprocket so that its convex side
faces the sprocket.
16 Refit the timing chain cover as described
in the previous Section.
11 Sump -
removal and refitting

Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Refer Chapter 1 and drain the engine oil.
Refit the sump drain plug.
3 Undo the retaining nuts and detach the
exhaust downpipe from the manifold flange.
Note that the flange gasket should be
renewed on reassembly. Allowing sufficient
clearance for sump removal, tie the exhaust
downpipe up with a suitable length of wire or
cord to prevent the system straining the
insulators. On catalytic converter-equipped
vehicles, avoid straining the oxygen sensor
wiring; if necessary, disconnect the sensor’s
multi-plug.
4 Remove the starter motor (see Chapter 5A).
5 Undo the two retaining bolts and remove
the clutch housing cover plate and, where
fitted, the auxiliary drivebelt lower cover from
inside the right-hand wheel arch.

6Undo the eighteen bolts securing the sump
to the base of the engine crankcase, then
prise free and lower the sump. If the sump is
stuck tight to the engine, cut around the
flange gasket with a sharp knife, then lightly
tap and prise it free. Keep the sump upright as
it is lowered, to prevent spillage of any
remaining oil in it. Also be prepared for oil
drips from the crankcase when the sump is
removed.
7 Remove any dirt and old gasket from the
contact faces of the sump and crankcase, and
wash the sump out thoroughly before refitting.
Check that the mating faces of the sump are
not distorted. Check that the oil pick-up
strainer is clear, cleaning it if necessary.
Refitting
8 Clean the gasket location faces. Apply a
dab of sealing compound to the mating faces
where the ends of each cork half-gasket are
to be fitted (see illustration) . Stick the new
cork gaskets into position on the block face,
using clean thick grease to retain them, then
locate the new rubber gaskets into their slots
in the timing chain cover and rear oil seal
carrier. The lugs of the cork gasket halves fit
under the cut-outs in the rubber gaskets (see
illustration) .
9 Before offering up the sump, check that the
gap between the sump and the oil baffle is
between 2.0 and 3.8 mm (see illustration).Do not use a dented or damaged sump, as
the indicated dimension is important for
correct engine lubrication.
10
Fit the sump into position, and fit the
retaining bolts. Initially tighten them all finger-
tight, then further tighten them in the sequence
shown through Stages 1 and 2, to the torque
wrench settings specified (see illustration).
Note that different tightening sequences are
specified for the tightening stages. Final
(Stage 3) tightening is carried out after the
engine has been started and warmed up.
11 Refit the lower plate to the front face of
the clutch housing and refit the auxiliary
drivebelt lower cover.
12 Refit the starter motor.
13 Check that the downpipe and manifold
mating faces are clean, then locate a new
gasket and reconnect the exhaust downpipe
to the manifold. Where applicable, use new
self-locking nuts, and tighten securely.
14 Check that the sump drain plug is fitted
and tightened to the specified torque, then
lower the vehicle to the ground.
15 Refill the engine with oil as described in
Chapter 1.
16 Reconnect the battery, then start the
engine and run it up to its normal operating
temperature. Check that no oil leaks are
evident around the sump joint.
17 After the engine has warmed up for
approximately 15 minutes, switch it off.
Tighten the sump bolts to the Stage 3 torque
wrench setting given in the Specifications, in
the sequence shown in illustration 11.10.
12 Oil pump -
removal and refitting
2
Removal
1 The oil pump is externally-mounted, on the
rear-facing side of the crankcase.
2 Chock the rear wheels then jack up the
front of the car and support it on axle stands
(see “Jacking and Vehicle Support” ).
3 Unscrew and remove the oil filter cartridge.
It should unscrew by hand, but will probably
be tight. Use a strap wrench to loosen it off, if
required. Catch any oil spillage in a suitable
container.
4 Undo the three retaining bolts and withdraw
the oil pump from the engine (see
illustration) .
5 Clean all traces of the old gasket from the
mating surfaces of the pump and engine.
Refitting
6 If the original oil pump has been dismantled
and reassembled and is to be re-used, or if a
new pump is to be fitted, it must first be
primed with engine oil prior to fitting. To do
this, turn its driveshaft and simultaneously
inject clean engine oil into it.
7 Locate a new gasket into position on the
pump mounting flange, then insert the pump,
engaging the drivegear as it is fitted (see
illustration) . Fit the retaining bolts, and
tighten to the specified torque wrench setting.

be fitted on reassembly. Tie the downpipe up
to support it.
18Before it is released and removed, the
cylinder head must first have cooled down to
room temperature (about 20ºC).
19 Unscrew the cylinder head retaining bolts
progressively in the reverse order to that
shown for tightening (see illustration 12.28).
The cylinder head bolts must be discarded
and new bolts obtained for refitting the
cylinder head.
20 Remove the cylinder head complete with
its manifolds. If necessary, grip the manifolds
and rock it free from the location dowels on
the top face of the cylinder block. Do not
attempt to tap it sideways or lever between
the head and the block top face.
21 Remove the cylinder head gasket. This must
always be renewed; it is essential that the
correct type is obtained. Save the old gasket, so
that the identification marks (teeth) can be used
when ordering the new one (see illustration).
Preparation for refitting
22The mating faces of the cylinder head and
cylinder block must be perfectly clean before
refitting the head. Use a hard plastic or wood
scraper to remove all traces of gasket and
carbon; also clean the piston crowns. Take
particular care during the cleaning operations,
as aluminium alloy is easily damaged. Also,
make sure that the carbon is not allowed to
enter the oil and water passages - this is
particularly important for the lubrication
system, as carbon could block the oil supply
to the engine’s components. Using adhesive
tape and paper, seal the water, oil and bolt
holes in the cylinder block.
23 Check the mating surfaces of the cylinder
block and the cylinder head for nicks, deep
scratches and other damage. If slight, they may be removed carefully with a file, but if
excessive, machining may be the only
alternative to renewal.
24
If warpage of the cylinder head gasket
surface is suspected, use a straight-edge to
check it for distortion. Refer to Part D of this
Chapter if necessary.
25 Ensure that new cylinder head bolts are
used when refitting and clean out the bolt
holes in the block. Screwing a bolt into an oil-
filled hole can (in extreme cases) cause the
block to fracture, due to the hydraulic
pressure.
Refitting
26 To prevent the possibility of the valves
and pistons coming into contact as the head
is fitted, turn the crankshaft over to position
No 1 piston approximately 20 mm below its
TDC position in the bore.
27 Locate the cylinder head gasket on the
top face of the cylinder block, locating it over
the dowels. Ensure that the gasket is fitted the
correct way up, as indicated by its “OBEN-
TOP” marking (see illustration) .
28 Lower the cylinder head into position,
ensuring that it fits over the locating dowels,
then insert the new retaining bolts. Hand-
tighten the bolts initially, then tighten them in
the order shown in the four stages to the
specified torque setting (see illustration).
Where possible, use an angular torque setting
gauge attachment tool for accurate tightening
of stages three and four. Alternatively, after
the first two stages, mark the bolt heads with
a dab of quick drying paint, so that the paint
spots all face the same direction. Now tighten
all the bolts in the sequence to the Stage 3
setting, by tightening them through the
specified angle. Finally, angle-tighten all the
bolts through the Stage 4 angle.
29 The camshaft sprocket should be
positioned so that its TDC index mark pointer
is in alignment with the TDC index spot mark
on the front end face of the cylinder head (see
illustration 3.6b).
30 Now turn the crankshaft pulley to bring its
TDC notch in alignment with the TDC (0)
indicator on the front face of the timing belt
cover, taking the shortest route (not vice-
versa) (see illustration 3.6a). 31
Refit the timing belt over the camshaft
sprocket, and then tension the belt as
described in Section 8.
32 The remainder of the refitting procedure is
a reversal of the removal process. Tighten all
fastenings to their specified torque setting
(where given). Refer to the appropriate Parts
of Chapter 4 for details on reconnecting the
fuel and exhaust system components, and to
Chapter 5B for details on reconnecting the
ignition system components. Ensure that all
coolant, fuel, vacuum and electrical
connections are securely made.
33 On completion, refill the cooling system
and top-up the engine oil (see Chapter 1 and
“Weekly Checks” ). When the engine is
restarted, check for any sign of fuel, oil and/or
coolant leakages from the various cylinder
head joints.

4 Where fitted, pull free the oxygen sensor
lead multi-plug, and disconnect it. If the
engine has been recently run, take particular
care against burning when working in the area
of the catalytic converter.
5 Undo the retaining nuts, and detach the
exhaust downpipe from the manifold. The
flange gasket must be renewed when
reconnecting. Where applicable, also detach
the downpipe at the rear of the catalytic
converter, and release it from the front
mounting.

way.
7Remove the starter motor as described in
Chapter 5A, then undo the retaining bolts, and
remove the clutch cover plate from the front
face of the bellhousing (see illustration).
8 Progressively unscrew the sump retaining
bolts and remove them. Support and lower
the sump pan, taking care not to spill any oil
remaining in it as it is removed. If the sump is
stuck to the base of the crankcase, prise it
free using a screwdriver, but take care not to
damage the sump flange face. If it is really
stuck in position, check first that all of the
bolts are removed, then cut around the sump
gasket with a sharp knife to help in freeing the
joint.
9 After the sump is removed, further oil will
almost certainly continue to drip down from
within the crankcase, some old newspapers
positioned underneath will soak up the
spillage whilst the sump is removed.
10 Clean the sump of old oil and sludge,
using paraffin or a suitable engine cleaner
solution. Clean any traces of old gasket and
sealer from the mating faces of the sump and
the crankcase.
Refitting
11 Smear a suitable sealing compound onto
the junctions of the crankcase-to-oil seal carrier at the rear and the crankcase-to-oil
pump housing at the front on each side
(see
illustration) .
12 Insert a new rubber seal in the groove in
the rear oil seal carrier and the oil pump case.
As an aid to correct sump alignment when
refitting it, screw ten M6 studs into the
cylinder block, in the positions circled in
illustration 13.14.
13 Fit a new gasket over the studs. Fit the
sump into position, ensuring that the raised
spacers sit in the gasket. Insert the bolts into
the available holes, and finger-tighten them
only at this stage. Now remove the studs and
fit the remaining bolts, again finger-tight.
14 Tighten the sump bolts in a progressive,
numerical sequence to the specified torque
wrench setting (see illustration) .
15 Fit the sump drain plug with a new sealing
washer, and tighten it to the specified torque
wrench setting.
16 Refit the clutch cover plate, the auxiliary
drivebelt lower cover, the front suspension
crossmember, the gearchange mechanism
stabiliser bar/exhaust forward mounting
bracket, and the starter motor with reference
to the relevant Sections and Chapters of this
manual as applicable.
17 Reconnect the exhaust downpipe as
described in Chapter 4E.
18 On completion, lower the vehicle, and fill
the engine with oil as described in Chapter 1.
Reconnect the battery negative lead.

Removal
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Remove the auxiliary drivebelt (see Chap-
ter 1).
3 Remove the crankshaft pulley (Section 6),
the timing belt covers (Section 7), the timing
belt, crankshaft sprocket and thrustwasher
(Sections 8 and 9), and the sump (Section 13).
4 Unscrew the retaining nut/bolts and remove
the oil pick-up pipe (see illustration).
5 Unbolt and withdraw the oil pump from the
front face of the engine. Clean the oil pump
for inspection. Refer to Section 15 for the
inspection procedures. The oil seal in the oil
pump housing should always be renewed
(Section 16).
Refitting
6 Before refitting the oil pump and the
associated fittings, clean off the respective
mating faces. A new oil pump gasket must be
obtained, as well as the seals and gaskets for
the other associated components to be
refitted.
7 When refitting the oil pump, precautionary
measures must be taken to avoid the
possibility of damaging the new oil seal as it is
engaged over the shoulder and onto its journal
on the crankshaft. Extract the Woodruff key
from the groove in the crankshaft, then cut a
thin plastic guide which will furl over and
protrude beyond the shoulder of the seal
journal on the crankshaft (see illus-
tration 14.9b) . This will allow the seal to ride
over the step, and avoid damaging the seal lip
as it is pushed into position on the crankshaft.
8 If a new oil pump is being fitted or the old
pump is to be re-used after cleaning and
inspection, first prime the pump by squirting
clean engine oil into it, and simultaneously
rotating the drivegear a few times (see
illustration) .

the radiator top hose from the thermostat
housing’s water outlet (see illustration).
9 Unscrew the retaining bolts, and remove
the water outlet from the thermostat housing.
10 Withdraw the thermostat from the housing
noting the position of the air bleed valve, and
how the thermostat is installed (which end is
facing outwards) (see illustration).
Testing
General check
11Before assuming the thermostat is to
blame for a cooling system problem, check
the coolant level, auxiliary drivebelt tension
and condition (see Chapter 1) and
temperature gauge operation.
12 If the engine seems to be taking a long
time to warm up (based on heater output or
temperature gauge operation), the thermostat
is probably stuck open. Renew the thermostat.
13 If the engine runs hot, use your hand to
check the temperature of the radiator top
hose. If the hose isn’t hot, but the engine is,
the thermostat is probably stuck closed,
preventing the coolant inside the engine from
escaping to the radiator - renew the
thermostat.
Caution: Don’t drive the vehicle without a
thermostat. The lack of a thermostat will
slow warm-up time. The engine
management system’s ECU will then stay
in warm-up mode for longer than
necessary, causing emissions and fuel
economy to suffer. 14
If the radiator top hose is hot, it means
that the coolant is flowing and the thermostat
is open. Consult the “Fault finding” section at
the end of this manual to assist in tracing
possible cooling system faults.
Thermostat test
15 If the thermostat remains in the open
position at room temperature, it is faulty, and
must be renewed as a matter of course.
16 To test it fully, suspend the (closed)
thermostat on a length of string in a container
of cold water, with a thermometer beside it;
ensure that neither touches the side of the
container (see illustration) .
17 Heat the water, and check the temperature
at which the thermostat begins to open;
compare this value with that specified. It’s not
possible to check the fully-open temperature,
because this occurs above the boiling point of
water at normal atmospheric pressure. If the
temperature at which the thermostat began to
open was as specified, then it is most likely
that the thermostat is working properly at all
temperatures. Remove the thermostat, and
allow it to cool down; check that it closes fully.
18 If the thermostat does not open and close
as described, if it sticks in either position, or if
it does not open at the specified temperature,
it must be renewed.
Refitting
All models
19 Refitting is a reversal of removal. Clean
the mating surfaces carefully, and renew the thermostat’s O-ring seal or housing gasket, as
applicable.
20
On Zetec engines, ensure that the
thermostat is fitted with its air bleed valve
uppermost.
21 Tighten the thermostat housing/water
outlet bolts to the specified torque.
22 Refill the cooling system (see Chapter 1).
23 Refit the air cleaner or air inlet components,
as applicable, if removed for access.
24 Start the engine and allow it to reach
normal operating temperature, then check for
leaks and proper thermostat operation.
5 Radiator electric cooling fan assembly - testing, removal
and refitting
2
Note: Refer to the warnings given in Section 1
of this Chapter before starting work.
Testing
1 If it is suspected that the cooling fan is not
operating when high engine temperature
would normally require it to do so, first check
the relevant fuses and relays (see Chapter 12).
2 Detach the wiring multi-plug from the
thermostatic switch, which is located either in
the thermostat housing or at the right-hand end
of the radiator, next to the bottom hose (see
illustration) . Using a suitable piece of wire,
bridge the two connections within the plug.
Switch the ignition on and check if the cooling
fan operates. If the fan now operates, the
thermostatic switch is at fault, and should be
renewed as described in Section 6. Remove the
bridging wire from the plug, and reconnect the
wiring connector to complete the test.
3 If the fan failed to operate in the previous
test, either the fan motor is at fault, or there is
a fault in the wiring loom (see Chapter 12 for
testing details).
Removal
All models except Turbo
4 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
5 Detach the wiring multi-plug from the fan
motor and unclip the wiring from the retaining
clips on the shroud (see illustration).
