1988 FIAT TEMPRA radiator

Please be sure to read the whole of this Chapter before carrying out any work on your car.
SAFETY FIRST!
You must always ensure that
safety is the first consideration
in any job you carry out. A
slight lack of concentration, or
a rush to finish the job quickly
can easily result in an accident,
as can failure to follow the
precautions outlined in
this manual.
Be sure to consult the
suppliers of any materials and
equipment you may use, and
to obtain and read carefully
any operating and health and
safety instructions that may
be available on packaging or
from manufacturers
and suppliers.
Raising the Car Safely
ALWAYS ensure that the vehicle is properly supported when
raised off the ground. Don't work on, around, or underneath
a raised vehicle unless axle stands are positioned under
secure, load bearing underbody areas, or the vehicle is driven
onto ramps, with the wheels remaining on the ground
securely chocked to prevent movement.
NEVER work on a vehicle supported on a jack. Jacks are made
for lifting the vehicle only, not for holding it off the ground
while it is being worked on.
ALWAYS ensure that the safe working load rating of any
jacks, hoists or lifting gear used is sufficient for the job, and
that lifting gear is used only as recommended by the
manufacturer.
NEVER attempt to loosen or tighten nuts that require a lot of
force to turn (e.g. a tight oil drain plug) with the vehicle
raised, unless it is safely supported. Take care not to pull the
vehicle off its supports when applying force to a spanner.
Wherever possible, initially slacken tight fastenings before
raising the car off the ground.
ALWAYS wear eye protection when working under the
vehicle and when using power tools.
Working On The Vehicle
ALWAYS seek specialist advice unless you are justifiably
confident about carrying out each job. The safety of your
vehicle affects you, your passengers and other road users.
DON'T lean over, or work on, a running engine unless it is
strictly necessary, and keep long hair and loose clothing well
out of the way of moving mechanical parts. Note that it is
theoretically possible for fluorescent striplighting to make an
engine fan appear to be stationary
-
double check whether it
is spinning or not! This is the sort of error that happens when
you're really tired and not thinking straight. So...
...DON'T work on your car when you're over tired.
ALWAYS work in a well ventilated area and don't inhale dust
- it may contain asbestos or other harmful substances.
NEVER run the engine indoors, in a confined space or over
a pit.
REMOVE your wrist watch, rings and all other jewellery before
doing any work on the vehicle
-
and especially when working
on the electrical system.
DON'T remove the radiator or expansion tank filler cap when
the cooling system is hot, or you may get scalded by escaping
coolant or steam. Let the system cool down first and even
then, if the engine is not completely cold, cover the cap with
a cloth and gradually release the pressure.
NEVER drain oil, coolant or automatic transmission fluid when
the engine is hot. Allow time for it to cool sufficiently to avoid
scalding you.
ALWAYS keep antifreeze, brake and clutch fluid away from
vehicle paintwork. Wash off any spills immediately.
TAKE CARE to avoid touching any engine or exhaust system
component unless it is cool enough not to burn you.

Fuses located on the auxiliary panel
The fuses protecting special devices (options, features of
special versions or devices with high power require-
ments) are on an auxiliary panel to the side of the fuse
box under the dashboard. It is much easier to remove
and replace auxiliary panel fuses if you first remove the
oddment tray and moulding fastened by 5 screws. The
panel also houses a number of relays:
20A Intake manifold heater (petrol engines).
20A Diesel fuel filter heater (diesel and turbo diesel
engines).
20A Headlight washer pump.
25A Front power windows.
25A Rear power windows.
10A Antilock braking system.
7.5A Low beam headlight dimming system (for countries
where headlights always need to be on.)
30A Radiator fan (diesel versions).
40A Radiator fan (turbo diesel versions with heater).
60A Radiator fan (turbo diesel versions with air condi-
tioning).
The arrangement of the fuses on the auxiliary panel
varies with the number and type of devices present.
The amperage is clearly marked on each fuse. ALWAYS
replace a blown fuse with one of the correct amperage.
NEVER 'fix' a fault by using a fuse of a higher amperage,
nor 'bridge' a blown fuse
-
it could cause a fire!
7f. When a fuse is 'blown'
its conductor wire (A) has
a gap in it.
If a fuse blows, find out
why and put it right
before fitting a new fuse.

Q Job 8. Change engine oil and filter.
SAFETY FIRST!
• Refer to the section on ENGINE OILS and RAISING

THE
CAR SAFELY in Chapter f, Safety First! before

carrying
out this work.
• You must wear plastic gloves when changing the oil.

Used
engine oil can severely irritate the skin and
is
carcinogenic.
Used diesel engine oil is an even greater

health
hazard.
•
Oil
drain plugs are often over-tightened, so take

care
that the spanner does not slip.

Take
care that the effort needed to undo the drain

plug
doesn't tip the car off its supports
-
remember to

use
wheel
chocks!

but not
so

hot that the oil can scald!
• Allow the oil to drain for at least ten minutes before
replacing the sump plug.
• You can use this time by renewing the oil filter.
IMPORTANT NOTE: The plug is a taper-fit and can
become very tight, necessitating the use of a long drive-
bar for its removal.
H INSIDE INFORMATION: On side-mounted drain holes,
as the oil empties, the angle of 'spurt' will change, so be
prepared to move the container. E3

8A. The
sump drain

plug is on
the
under-side of the

sump on
petrol
engines, and on the

side
of the sump
(timing belt end of
engine) on the

diesel.
The plug has

a
recessed
hexagonal head and you will need either a sump plug
spanner, a large Allen key, or a 'Hex' headed socket fitted to a

socket
wrench.
8B. Once the initial
tightness of the
plug has been
released, unscrew
the last few turns
by hand, holding
the plug in place
until the threads
have cleared, then
withdrawing it
smartly to allow oil to flow into the receptacle beneath.
expert22
8C. On all engines,
including diesel, the
oil filter is mounted
low on the front of
the engine block,
towards the timing
belt. Use a strap or
chain wrench to
unscrew the old
filter. Note that
there may be a lot of oil spilt as the filter seal is broken, so
keep the drip tray beneath it.

—I Job 13. Check cooling system.
SAFETY FIRST!
• The coolant level should be checked
-
and the
cooling system worked on, ONLY WHEN THE
COOLANT IS COLD. If you remove the pressure cap or
bleed screws when the engine is hot, scalding coolant
will spurt out.
• Keep anti-freeze away from children. If it is acciden-
tally swallowed or contacts skin or eyes, rinse
immediately with plenty of water and seek immediate
medical help.
Examine the cooling system hoses, looking for signs of
splitting, chafing and perishing. Squeeze the top and bottom
radiator hoses. Any hard, brittle areas or crackling sounds tell
you that the hoses are decomposing from the inside
-
replace-
ments needed!
SAFETY FIRST!
If
a
clearance is outside the tolerances shown in Chapter 3,

Facts
and Figures, the relevant shim will have to be changed.
New
shims
are available from your FIAT dealer. This work is
fully described in Chapter
6,
Repairs and Replacements.
10E. You must
always use a new
gasket, especially in
view of the oil level
mentioned earlier.

off (taking great care not to
damage the stub beneath!)
and replace with screw-
tight clips, when fitting a

any 'teeth' are
missing, replace
the belt straight
away. If the belt

breaks
the valves may collide with the pistons, causing serious
engine damage. Camshaft belt replacement is described in

Chapter 6,
Repairs and Replacements, or you may wish to

have
your FIAT dealer carry out the work for you. If you can
twist the belt through more than 90 degrees, it needs re-
tensioning. Also see Chapter
6,
Repairs and Replacements.

It is
ESSENTIAL that you renew the camshaft drive belt at the
recommended interval. See the Service Interval Chart at the

start
of this chapter. Chapter
6,
Repairs and Replacements
explains how to carry out the work.
14B. Loosen the
worm-drive clip
(arrowed) and
pull off the
bottom radiator
hose.

14C. Also open
the drain plug or
tap (B) at the
centre of the rear
flank of the
engine block on
both petrol and
diesel engines. Drain the coolant into a container. On models
with a separate expansion tank, detach the hose from the
expansion tank and drain the tank.
Q INSIDE INFORMATION: From time to time it's a good
idea to flush the cooling system. With the bottom hose
re-connected, disconnect and remove the top hose from
the radiator. Insert the end of a garden hose first into
the hose (packing the gap with a rag) and then the
radiator inlet, flushing the system in both directions until
the water comes out clear. Q
IMPORTANT NOTE: Flush first with the heater control
turned OFF until the engine and radiator are clear, so
that you don't flush sediment into the heater. Then with
the heater turned ON, flush the heater system out.
14D. To prevent air-locks
forming in the cooling
system as it is refilled (all
hoses and the drain plug
reconnected, of course!),
most models have two
air-bleed screws strategi-
cally positioned in the
system. These should be
opened before refilling.
The first (B or C) is
located on the right-
hand side of the radiator
(type dependant on
version)...
PART C: TRANSMISSION
• Job 15. Check manual gearbox oil level.
The combined oil level and filler plug is on the forward-facing
side of the gearbox. Check the level with the car on level
ground.
15. From beneath the car, wipe
around the filler plug with a rag
to prevent dirt contamination.
Remove the plug
-
using a 10
mm Allen key
-
and top-up if
necessary, using the specified
Tutela transmission oil (see
Chapter

undo the screws
by two or three
turns. Retighten both screws when air-free coolant emerges.
This is the petrol engine...
14F. ...and this
the diesel engine
location.
H INSIDE
INFORMATION:
It seems that
latest Tipos and
Tempras were
built without some or all bleed screws. Ryauto
recommend removing the highest point of the top hose,
refilling with coolant, while an assistant refits the hose
smartly, losing as little coolant as possible. D
Refill the cooling system with a 50/50 mixture of clean water
and fresh Paraflu anti-freeze. Tighten the bleed screws (or
hose) when coolant, and not air, comes out steadily. Run the
engine for a few minutes and bleed again.
IMPORTANT NOTE: It is highly likely that more air will be
dislodged when you first use the car. Keep your eye on
the coolant level (See Job 2)
-
perhaps carrying some
50/50 diluted coolant with you for the first few journeys.
• Job 16. Change manual gearbox oil.
16. The combined
gearbox and final
drive oil should be
drained at the time
shown in the
Service Interval
Chart. Do so only
after the car has
been used and the
gearbox oil is warm, so that it flows well. Remove the drain
plug (on the end-face of the gearbox, accessed from beneath
the car
-
not much room to get a spanner in!) and drain the
oil into a container. (See page 8 on oil disposal.) Leave for 10
minutes to drain completely, and refill with the correct grade
of Tutela transmission oil through the level/filler plug, as
described in Job 15.

26B. If adjustment is
necessary, slacken the
tensioning nut (A) and
the alternator pivot (B),
on all models. (These
are two typical
layouts.)
Use a length of wood
to pivot the alternator
away from the engine
block but take great
care not to damage the
alternator casing.
Tighten the nuts/bolts
when the tension is correct.
RIBBED BELTS ONLY
If your vehicle is fitted with a ribbed belt, pivot the alternator
as described above and tighten it when you can just twist the
belt by 1/4 turn in the middle of its longest run.
IMPORTANT NOTE:
• Belt tension should only be adjusted when the engine
is cold.
• After adjustment, run the engine for 15 to 30 seconds,
to allow the belt to bed-in, then check again.
• Experience mechanics claim that belts often go slack
when the engine heats up, producing belt squeal.
• If this happens on your vehicle, adjust the belt again
when the engine is hot. Wear industrial leather gloves
and long-sleeved overalls and take very great care not to
burn yourself on the hot engine or exhaust.
If there is an auxiliary unit, such as an air conditioning pump,
driven by a separate drive belt, examine and adjust it as
described here.
Q Job 27. Check electric fan operation.
Drive the car until it is at normal operating temperature. Park
outdoors and, with the gearbox in neutral (or 'P' in the case of
an automatic) leave the engine running. At just above normal
temperature the electric cooling fan should come on, and
then go off again when the temperature drops. Refer to your
temperature gauge, if fitted. If the fan doesn't behave, check
the thermo-switch on the radiator, along with all connections
and wires in its circuit with the fan motor. See Job 13 and
Chapter
6,
Repairs and Replacements.
• Job 28. Run diagnostic ignition/injection test.
DIAGNOSTIC TEST
28A. Have your FIAT dealer
carry out a diagnostic test,
plugging his tester into the
diagnostic socket tucked away
at the front of the passenger-
side footwell.
EMISSIONS TESTS
Vehicles fitted with the Mono-Jetronic fuel injection system
are not fitted with adjustment screws. The system is self-
regulating. However, specified annual checks carried out with
an exhaust gas analyser will provide essential information on
the condition of the injection/ignition system, the catalytic
converter and the engine itself.
28B. The checks are carried out twice: once with the test
sensor at least 300 mm into the end section of the exhaust
pipe (a). (If the shape of the end section of the exhaust pipe is
such that the sensor cannot be completely introduced, a
special extension pipe must be added ensuring that the joint
with the car's tail-pipe is sealed.); the second after undoing
the cap or nut on the exhaust pipe upstream of the catalytic
converter (b).
The following table shows the test limits for carbon monoxide,
unburned hydrocarbons (in parts per million) and carbon
dioxide:
CO (%) HC (p.p.m.) C02(%)
Upstream of the catalyzer (a) 0,4 -h 1 500/600* >12
Downstream of the catalyzer (b)
=£
0,35 =s 90 >13
* FIAT's figures vary.
IMPORTANT NOTE: The engine must be at its normal
operating temperature and normal tick-over speed.
• if the percentage concentration of CO upstream of the
catalytic converter is not within the limits in the table,
check:
• the Lambda sensor
-
see Job 37.
• air penetration around the Lambda sensor housing.
• faults in the ignition or injection systems. (First try
renewing the spark plugs, distributor cap and HT leads.)
If, at the same time, the concentration of hydrocarbons
is not less than 500/600 parts per million (FIAT'S figures
vary), check:
• the ignition timing (see Job 25).
• the valve clearances (see Job 9).
• the valve gear timing (see Job 12).
• the engine compression. (You will need to remove the
spark plugs, fit a compresson tester to each plug
aperture in turn and crank the engine. See the FACT FILE
on page 51.)
