1988 FIAT TEMPRA wiring

and explosions. Do not allow resin or 2-pack adhesive hardener,
or that supplied with filler or 2-pack stopper, to come into
contact with skin or eyes. Read carefully the safety notes
supplied on the can, tube or packaging and always wear
impervious gloves and goggles when working with them.
Fluoroelastomers
Fluoroelastomers are commonly used for oil seals, wiring and
cabling, bearing surfaces, gaskets, diaphragms, hoses and '0'
rings. If they are subjected to temperatures greater than 315
degrees C, they will decompose and can be potentially
hazardous. Some decomposition may occur at temperatures
above 200 degrees C, and it is obvious that when a car has
been in a fire or has been dismantled with the assistance of a
cutting torch or blow torch, the fluoroelastomers can
decompose in the manner indicated above.
According to the Health and Safety Executive, "Skin contact
with this liquid or decomposition residues can cause painful and
penetrating burns. Permanent irreversible skin and tissue
damage can occur". Damage can also be caused to eyes or by
the inhalation of fumes created as fluoroelastomers are burned
or heated.
After a vehicle has been exposed to fire or high temperatures:
1. Do not touch blackened or charred seals or equipment.
2. Preferably, don't handle parts containing decomposed
fluoroelastomers, but if you must, wear goggles and PVC
(polyvinyl chloride) or neoprene protective gloves whilst doing
so. Never handle such parts unless they are completely cool.
3. Contaminated parts, residues, materials and clothing,
including protective clothing and gloves, should be disposed of
by an approved contractor to landfill or by incineration
according to national or local regulations. Oil seals, gaskets and
'0' rings, along with contaminated material, must not
be burned.
1. Always have a fire extinguisher of the correct type at arm's
length when working on the fuel system. If you do have a fire,
DON'T PANIC. Use the extinguisher effectively by directing it at
the base of the fire.
2. NEVER use a naked flame anywhere in the workplace.
3. KEEP your inspection lamp well away from any source of
petrol (gasoline) such as when disconnecting a carburettor float
bowl or fuel line.
4. NEVER use petrol (gasoline) to clean parts. Use paraffin
(kerosene), white spirits, or, a proprietary degreaser.
5. NO SMOKING. There's a risk of fire or of transferring
dangerous substances to your mouth and, in any case, ash
falling into mechanical components is to be avoided.
FACT FILE: FOUR WHEEL DRIVE CARS
• Whenever you have to raise a wheel off the
ground and turn it by hand, always ensure that
the opposite-side's wheel to the one being lifted is
also off the ground and free to turn and that both wheels remaining
on the ground are held by the parking brake (if possible) and
securely chocked in both directions.
• ALWAYS have the gearbox in neutral (or 'N' in the case of
automatics). In the case of
some
4 wheel drive automatics and those
with permanent 4WD, it is necessary to disengage the 4WD system
by special means.
• Consult your handbook or seek advice from your main dealer.
6. BE METHODICAL in everything you do, use common sense,
and think of safety at all times.
ENVIRONMENT FIRST!
The used oil from the sump of
just
one car
can
cover
an
area of
water the size of two football pitches, cutting off the oxygen
supply
and
harming swans, ducks, fish and other river lift.
When you drain your engine oil
-
don't oil the drain!
Pouring oil
down the
drain will
cause
pollution. It is
also an
offense.
Don't mix used
oil with other
materials, such
as paint and
solvents,
because this
makes
recycling
difficult.
Take used oil
to an oil
recycling bank.
Telephone
FREE on 0800 663366 to find the location of your nearest oil
bank, or contact you local authority recycling officer.

• Job 20. Check/adjust clutch. CABLE OPERATED CLUTCH

linkage can stretch over a period of time and may need
adjustment. The adjuster is on top of the gearbox, reached
from inside the engine bay.

• Job 21. Check auto, transmission selector cable.
It should only be possible to start the engine when the gear
selector is in the 'P' or 'N' position. Place it in each of the
other positions and try to start the car. If it starts, the fault
must be put right! Also check that, with the ignition off and
the selector lever in 'D' (Drive), 'L' (Low), 'R' (Reverse) or 'N'
(Neutral), the timed warning buzzer should sound. If it
doesn't, the selector cable adjustment may be faulty.

SAFETY FIRST!
• You may minimise the risk of shock when the engine is running by wearing thick rubber gloves and by NEVER
working on the system in damp weather or when standing on damp ground. Read Chapter 1, Safety First! before
carrying out any work on the ignition system.
• ELECTRONIC IGNITION SYSTEMS INVOLVE VERY HIGH VOLTAGES! All manufacturers recommend that only trained
personnel should go near the high-tension circuit (coil, distributor and HT wiring) and it is ESSENTIAL that anyone
wearing a medical pacemaker device does not go near the ignition system.
• Stroboscopic timing requires the engine to be running
-
take great care that parts of the timing light or parts of
you don't get caught up in moving components!
• Don't have loose clothing or hair.

box back until it's clear of
the clutch and lower it to
the ground using a
hydraulic stand or trolley
jack.
IMPORTANT NOTE: Refer to PART A: ENGINE, Jobs 8
and 9 in connection with this Job.
• Step 1: Refitting is the reverse of the removal work
carried out in Job 1 but bear in mind the following:
Q Step 2: Centralise the clutch driven plate, if it has been
disturbed. See Job 3.
• Step 3: NON-HYDRAULIC CLUTCHES ONLY. Adjust the
clutch cable. See Job 4
Q Step 6: Raise the front of the car and support securely on

axle stands.
Remove the road wheels and the previously
slackened hub nuts.
Q Step 7: Remove the wheel arch protective shields.
Q Step 8: Disconnect the speedometer cable from the
gearbox. (If digital instrumentation, disconnect the wiring

from
the sender unit.)
Q Step 9: Disconnect and remove the starter motor and

unplug
the reverse light connector and the earth lead from

the
transmission housing.
Q Step 10: Undo the trackrod ends securing nuts and use a
suitable 'splitter' tool to part the balljoints from the steering

arms.
Slacken the drive-shaft inner boot securing clips. Undo

the pinch
bolts fixing the stub axles to the suspension struts,

pull
the stub axles clear and extract the drive-shafts.
0 Step 11: Support the engine at the gearbox end, just

flywheel guard (b) and the exhaust bracket (c).
• Step 5: With

the
car
still
on the
ground, loosen

the nuts
fixing the
constant velocity

joints
to the hubs.
These require an
enormous force

to be
tightened or
released (see

Chapter 3,
Facts and Figures) and they will have been
staked. There is a severe risk of pulling the car off supports if

you
attempt to undo these nuts while the car is raised off the
