1988 FIAT TEMPRA Service And Repair Manual

50A. Remove the two

bolts
(one or both of
them also the wheel
positioning stud/s)...
50B. ...and remove
the
drum.
Clean the
inside of the drum and
the brake with aerosol

brake
cleaner. If the
drum is badly scored

or cracked,
replace it.
50F. So that you don't
have to bleed the
system, release and
disconnect the parking
brake cable (arrowed)
and lift the caliper out
of the way, suspending
it on a piece of wire so
that no strain is placed
on the flexible hydraulic
hose.
50G. The brake pads are simply lifted away.
50E. Using a pair of
spanners, as shown,
remove the two
retaining bolts. These
bolts are self-locking
and FIAT recommend
that they should be
replaced each time they
are removed or if they
become loose.
Examine the brake

shoes
for wear or oil
contamination. If the
latter, the wheel cylinder is probably leaking (see 50C) and the

shoes will
have to be scrapped. FIAT recommend a minimum

1.5 mm
shoe lining thickness, but it's advisable to replace

shoes
well before they're this thin.
50C. Fold back each of

the
two rubbers on

the wheel
cylinder.
Any
fluid
found inside
requires a new
cylinder. However,
newish cylinders will

have a
little of their
special grease still in
there.

50D. Take
special care

to wash
all the brake

dust
away from the
automatic adjuster
mechanism with
aerosol brake cleaner.

Make
sure that it is

not seized
but if it is,

you will
have to strip

down
the assembly (see Chapter
6,
Repairs and

Replacements)
and free off or replace. Add brake grease very
sparingly (NOT ordinary grease) to the mechanism.
IMPORTANT NOTE: For information on replacing missing
or damaged springs, brake shoes or wheel cylinders, see
Chapter
6,
Repairs and Replacements.
DISC REAR BRAKES

With
the rear of the car raised and safely supported (see

Chapter 1,
Safety First) and the rear wheels removed, brake

pad
inspection can be carried out by looking through the
aperture in the caliper body. However, as for the front brakes,

you are
recommended to remove the calipers. See notes at

the
start of Job
49.
The pads should be replaced as detailed in

Chapter 6,
Repairs and Replacements. Minimum thickness

is 1.5 mm -
but don't let them get this low!
• Job 51. Check/adjust handbrake.
The handbrake is intended to 'set' itself in use as the rear
brake self-adjusters operate. If the handbrake seems not to
work, even though lever travel is not excessive, remove the
rear drums and examine the brake shoes (see Job 50) and the
self-adjuster mechanism, to ensure that it has not seized. The
handbrake may need adjusting when, after a time, the
handbrake cable stretches or if the rear brake friction materials
are replaced.
IMPORTANT NOTE: On rear disc brake cars, the
handbrake-end of the mechanism is the same as for
drum brake cars. At the brakes, the clearance is adjusted
automatically, provided that the adjuster, built in to the
caliper assembly, has not seized. If it has, replace the
caliper.
SAFETY FIRST!
Raise the rear of the car to adjust the handbrake. It
is

ESSENTIAL to ensure the front wheels are securely
chocked in both directions, and that axle stands are
used to support the car.
IMPORTANT NOTE:
• Follow Job 49
carefully for further
information such as
on checking the
caliper seals, the
condition of the disc,
and lubricating the
pad backing plates.
• Before fitting new
pads, turn the caliper
piston clockwise until it goes fully in.
• Pump the brake pedal repeatedly to adjust the pad
positions and top up with fresh brake fluid.

51. Apply the
handbrake lever by
one 'click' of the
ratchet. From inside
the car, turn the
adjusting nut (a)
until the cable is
drawn taut. Pull the
handbrake up two
more 'clicks' and check that both rear wheels are now
'locked'. Check also that both rear wheels are completely free
when the handbrake is fully OFF. When everything works
properly, lower the car to the ground, and check again that
moving the handbrake through about three notches is suffi-
cient to hold the car stationary. A proper check of handbrake
efficiency can only be carried out by a garage with a 'rolling
road' brake tester.
Q Job 52. Check brake pipes.
FLEXIBLE HOSES
Check the flexible brake pipes that connect the calipers to the
metal pipes on the body. Try bending back on themselves
those that are not contained in a protective coil, and look for
any signs of cracking, particularly at the bends. Check them all
for signs of rubbing, splitting, kinks and perishing of the
rubber. Check hoses for 'ballooning' with the brake pedal
pressed.
RIGID PIPES
Check all rigid pipes for signs of damage or corrosion and
check that all of the locating clips are sound and in place.
• Job 53. Change brake hydraulic fluid.
Change the brake fluid at the recommended interval. See
Chapter
6,
Repairs and Replacements, PART H: BRAKES,
Job 15.
H INSIDE INFORMATION: Brake fluid absorbs water from
the air. This corrodes brake components and can cause
total brake failure. With brakes applied heavily, the fluid
can heat to above 100 degrees Celsius, the water
vaporises, and the pedal goes to the floor! B
PART H: BODYWORK & INTERIOR
• Job 54. Lubricate hinges and locks.
Apply a few drops of light oil (from either an aerosol or oil
can) to the hinges of the bonnet, doors and tailgate. Dip the
door/tailgate key in graphite powder and insert the key to
lubricate the lock barrels. Grease the door and tailgate latch
mechanism (aerosol grease is handy), the bonnet release
mechanism (and the tailgate's, if applicable) and the cable
end. Don't forget the fuel tank flap hinge and the locking cap
- it's a stopper when it jams!
• Job 55. Check windscreen.
Clean the windscreen with a proprietary glass cleaner and
examine it for stone chips, cracks and scoring. While some
degree of damage is acceptable, the strict MoT Test regula-
tions limit the amount and position of such defects. Some
screen chips can be repaired and made invisible.
• Job 56. Check seat and seat belt mountings.
Your car's seat and safety belt mountings and backrest
adjustment locking mechanism will be checked as part of the
annual test, but it pays to check them beforehand. Also,
regularly check that the seat belts: a) retract easily and
smoothly, and b) 'hold' when you snatch them, or under
sharp braking.
Q Job 57. Check headlight alignment.
Some vehicles are fitted with an automatic headlight levelling
device. On these vehicles, each of the headlights is adjusted
according to the vehicle height and no height levelling
adjustment is possible.
57. On the majority of vehicles, there is a manual height
adjuster. When the vehicle is unladen, the lever should be in
position (1): when fully laden, in position (2). The height
adjusters are on the inner side of each headlight and are
visible with the bonnet open. Make sure that the adjusters are
set to the 'unladen' position before the headlights are
adjusted. Don't confuse the beam correctors with the vertical
alignment screw (A) and the horizontal adjuster screw (B).
• Job 58. Check underbody.
Check the condition of the underbody for damage and
corrosion. Take a tin of waxy underbody seal and a brush
under the car and replace any missing underbody seal.

RIGHT SIDE

—1 Job 59. Check spare tyre.

This
job should ideally be carried out every month or two
-
you
never know when you're going to need that spare! But if you
haven't remembered, do it at the time shown on the Service
Interval Chart at the latest.
Q INSIDE INFORMATION: Put in the maximum recom-
mended pressure for heavy-duty use
-
it's always easier
to let some air out if necessary, than to put some in. Lift
the spare out check the 'hidden' lower side wall
for cracking. See Job 6. E9
PART I: ROAD TEST
Q Job 62. Road test and specialist check
-
after
every service.
Before you can claim to have 'finished' working on your car,
you must check it, test it, and, if necessary, have a qualified
mechanic check it over for you.

If you
are not a qualified mechanic, we strongly recommend
having someone who is a properly qualified mechanic
-
your
FIAT dealership perhaps
-
inspect all of the car's safety-related

items
after they have been worked on at home and before

using
the car on the road.
You'll have to remove the toolkit and the wheel to get at the
valve
-
under the boot floor on most models but to one side of
the rear compartment on Estate versions.
• Job 60. Change pollen filter.
When fitted to the fresh air intake, replace it at the scheduled
mileage interval.
• Job 61. Replace airbag gas generator.
Have your FIAT dealer replace the airbag gas generator 10
years after the car was built
-
see the label inside the car's
glove compartment door.
• Before setting out, check that the lights, indicators and in-
car controls, as well as seat belts and seat adjustments, all
work correctly.
• Run the car for several minutes before setting out then turn
off, check fluid levels and check underneath for leaks.
• Check that the steering moves freely in both directions and
that the car does not 'pull' one way or the other when driving
in a straight line
-
but do bear in mind the effect of the
camber on the road.
• Make sure that the brakes work effectively, smoothly and
without the need for 'pumping'. There should be no juddering
or squealing.
• Check that the car does not 'pull' from one side to the
other when you brake firmly from around 40 mph. (Don't
cause a skid and don't try this if there is any following traffic.)

CHAPTER 6
REPAIRS AND REPLACEMENTS
This chapter shows you how
to remove and overhaul all
the major 'wearing' parts of
the car. We deliberately don't
show how to rebuild major
components, such as the
gearbox, or differential. You
are much better off, in terms
of time, cost and the
provision of a guarantee, to
buy a replacement unit.
The same applies to major
electrical components, such
as alternator and starter
motor. If, as we recommend,
you stick to 'original' FIAT
replacement parts, you will
maintain the original quality
of your car.

FACT FILE: TIPO and TEMPRA ENGINE TYPES
PETROL ENGINES: The engines covered by
this manual are by far the most commonly
found in the UK. There may be the odd few with
different capacities or specifications which have been imported
from other countries but even they are usually similar. Here we
are concerned with one type of OHC (overhead camshaft)
PETROL engine, in 1372cc (1400) and 1581cc (1600) capacities.
They are best identified by the fact that the 1400 has its
distributor mounted on the side of the cylinder block and the
1600 has a distributor which is mounted on the end of the
camshaft, flywheel end.
DIESEL ENGINES: The Diesel engines covered here are the
1697cc (1700), the 1929cc (1900) and the 1929cc (1900) turbo.
It would take a trained eye to spot any differences between the
normally aspirated engines, but the turbo mounted on the
exhaust manifold together with its associated extra 'plumbing'
easily identifies the most powerful version.

Mi*^^ Zc+sc, / • The crankshaft pulley nut
n^^ will be difficult to turn.
• If the engine is in the car,
engage a gear (or 'Park' in the case of an automatic)
and have an assistant hold the footbrake down very
firmly. This will stop the engine from turning.
• Alternatively, with the starter motor removed, you
can have a helper prevent the flywheel ring gear from
turning with a large screwdriver.
• Step 4: Before removing the belt, put the pulley nut back
onto the crankshaft, take the car out of gear (if the engine is
still in the car) and remove the spark plugs. You can now turn
the engine in a clockwise direction using the refitted crank
pulley nut
-
without the pulley, of course!
• Step 5A: With
the timing belt still in
place, turn the engine
so that the timing
mark on the camshaft
sprocket lines up with
the one on the front
cover. On some
engines, the front
cover looks like this...
• Step 5B:
...while on the
majority, it looks
like this. The top
part of the cover
backplate slides
out so that the
plastic pip is level
with the camshaft
sprocket. Turn
the sprocket so that the timing mark on the sprocket lines up
with this pip.
IMPORTANT NOTE: It is false economy to refit a used
timing belt. If the belt breaks, it will cause complete
engine failure so always fit a new one.
• Step 1:
Disconnect the battery

and
remove the
alternator drivebelt as
described in PART C:

COOLING
SYSTEM
0 Step 2: Take off

the timing
belt cover.

This is held
by a total

of
four bolts (arrowed).
• Step 3: Take off

the
crankshaft pulley

nut and
remove the
pulley.

• Step 6A: You
must also check
that the mark (a)
on the timing belt
pulley lines up
with the reference
mark (b) on the oil
seal housing. It will
be essential that
all of these marks
align when the
new belt is fitted!
Q Step 6B: On earlier engines rotate the crankshaft so that
the reference mark on the driving pulley is in line with the
TDC reference mark on the front cover. If the engine is in the
vehicle, position the crankshaft at TDC using the reference
marks on the flywheel and bellhousing window.
• Step 7:
Slacken off the belt
tensioner...
• Step 8: ...and
remove the camshaft
timing belt.
Q Step 9: The new
belt must be fitted with
the arrows, printed on
the outside of the belt,
pointing in the direction
of engine rotation.
Ensure that the timing
marks are still aligned.
• Step 10: Engage the belt with the crankshaft sprocket
first, then in turn, the auxiliary and camshaft sprockets. Finally,
feed it round the tensioner pulley. Also, as a double-check
that the belt is not 'out', ensure that the yellow lines on the
belt align exactly with the timing marks on the camshaft
sprocket and crankshaft sprocket.
Q Step 11: Slacken the tensioner nut and push the pulley
onto the belt until taut. Check that the timing marks are still
correctly aligned. Still pressing the pulley against the belt,
tighten its locking nut.
• Step 12: H INSIDE INFORMATION! Before finally
tightening the tensioner nut when adjusting the tension,
remove it, clean the thread and apply Loctite
Threadlocker to help stop the nut and washer shaking
loose. Q
Q Step 13: Turn the engine through two complete turns
clockwise and re-check the belt tension. Adjust again if
necessary.
Q INSIDE INFORMATION! Without the special tools used
by FIAT, you can make an approximate adjustment by
tensioning the belt so that it can be twisted through 90
degrees (one quarter turn) mid way between the
camshaft and auxiliary shaft sprockets, using your finger
and thumb. If you can't put enough pressure on the belt
tensioner with your fingers, push a pair of bolts into the
two holes in the tensioner and lever between them to
turn the tensioner. B

Q INSIDE INFORMATION! • Before removing the
cylinder head, make sure the engine is stone cold.
• Undo the cylinder head bolts strictly in the order laid
out in Step 18.
• These precautions help to prevent cylinder head
distortion.
• The new cylinder head gasket should stay in its
packaging until required, to avoid contamination by oil

or grease.
B
FACT FILE: SPECIAL TOOL PROBLEMS
SOLVED!
• It is possible to remove and replace the
cylinder head complete with the camshaft
housing - but it is very difficult without
FIAT's special cranked tool to get round the camshaft
housing.
• You CAN undo the bolts with a ring spanner, but you
CAN'T torque them down properly again!
• Because the gasket between the housing and the head could
also be suspect, we strongly recommend that you do it 'our'
way, by removing the camshaft housing even though you will
have to re-set the valve clearances.

SAFETY FIRST! • Step 7:
Disconnect the
electrical leads from
the following: the
inlet manifold
• Step 2: Disconnect both battery leads, negative
