1988 FIAT TEMPRA automatic transmission fluid

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.

Running The Vehicle
NEVER start the engine unless the gearbox is in neutral (or
'Park' in the case of automatic transmission) and the hand
brake is fully applied.
NEVER run catalytic converter equipped vehicles without the
exhaust system heat shields in place.
TAKE CARE when parking vehicles fitted with catalytic
converters. The 'cat' reaches extremely high temperatures and
any combustible materials under the car, such as long dry
grass, could be ignited.
Personal Safety
NEVER siphon fuel, antifreeze, brake fluid or other such toxic
liquids by mouth, or allow contact with your skin. Use a
suitable hand pump and wear gloves.
BEFORE undertaking dirty jobs, use a barrier cream on your
hands as a protection against infection. Preferably, wear
suitable gloves, available from DIY outlets.
WEAR IMPERVIOUS GLOVES for sure when there is a risk of
used engine oil coming into contact with your skin. It can
cause cancer.
WIPE UP any spilt oil, grease or water off the floor
immediately.
MAKE SURE that spanners and all other tools are the right size
for the job and are not likely to slip. Never try to 'double-up'
spanners to gain more leverage.
SEEK HELP if you need to lift something heavy which may be
beyond your capability. Don't forget that when lifting a heavy
weight, you should keep your back straight and bend your
knees to avoid injuring your back.
NEVER take risky short-cuts or rush to finish a job. Plan ahead
and allow plenty of time.
BE METICULOUS and keep the work area tidy
-
you'll avoid
frustration, work better and lose less.
KEEP children and animals right-away from the work area and
from unattended vehicles.
ALWAYS tell someone what you're doing and have them
regularly check that all is well, especially when working alone
on, or under, the vehicle.
Fire!
Petrol (gasoline) is a dangerous and highly flammable liquid
requiring special precautions. When working on the fuel
system, disconnect the vehicle battery earth (ground) terminal
whenever possible and always work outside, or in a very well
ventilated area. Any form of spark, such as that caused by an
electrical fault, by two metal surfaces striking against each
other, by a central heating boiler in the garage 'firing up', or
even by static electricity built up in your clothing can, in a
confined space, ignite petrol vapour causing an explosion.
Take great care not to spill petrol on to the engine or exhaust
system, never allow any naked flame anywhere near the work
area and, above all, don't smoke.
Invest in a workshop-sized fire extinguisher. Choose the
carbon dioxide type or preferably, dry powder but NEVER a
water type extinguisher for workshop use.
DON'T disconnect any fuel pipes on a fuel injected engine
without following the advice in this manual. The fuel in the
line is under very high pressure
-
sufficient to cause serious
injury. Remember that many injection systems have residual
pressure in the pipes for days after switching off. If necessary
seek specialist advice.
Fumes
Petrol (gasoline) vapour and that given off by many solvents,
thinners, and adhesives are highly toxic and under certain
conditions can lead to unconsciousness or even death, if
inhaled. The risks are increased if such fluids are used in a
confined space so always ensure adequate ventilation. Always
read the maker's instructions and follow them with care.
Never drain petrol (gasoline) or use solvents, thinners
adhesives or other toxic substances in an inspection pit. It is
also dangerous to park a vehicle for any length of time over
an inspection pit. The fumes from even a slight fuel leak can
cause an explosion when the engine is started.
v ,,, Oil;::;s

• Repeat this operation three more times until the
complete code number has been entered, if the code
has been entered in correctly LED B will start flashing.
• Release button A (see illustration
1B).
Red LED B
flashes for 8 seconds indicating the new remote unit's
code has been stored.
IMPORTANT NOTE: If the LED does not illuminate
when remote unit button (illustration 1B, button
O is pressed, change the remote unit's battery.
• Insert the emergency key A into the emergency switch
slot in the glove compartment turn the key to the left to
switch the alarm off (see inset).
• Turn the key back towards its original position to
switch the alarm system back on.
IMPORTANT NOTE: As the alarm system absorbs
energy, if you are not planning on using the car
for a long period of time, turn the alarm exclusion
key to the off position, so as not to run the vehicle
battery down.
• 2. IGNITION SWITCH AND
STEERING COLUMN LOCK
IGNITION SWITCH
2. The ignition/steering column lock key, once inserted
in the ignition lock, can be placed in any of the
following four positions:
• PARK
-
With the key in this
position the side and tail lights
can be turned on, the steering
column locked and the keys
can be removed. Press button
A to turn the key to PARK.
• STOP
-
When the key is
turned to the STOP position the steering column will be
locked, and the keys can be removed.
• MAR
-
This is the driving position. When the key is in
this position all the electrical devices are energised.
• AW
-
Turning the key to this position starts the
engine.
STEERING COLUMN LOCK
• LOCKING
-
To apply the steering wheel lock turn the
steering wheel slightly to the left or right when the key is
at STOP or PARK.
• UNLOCKING
-
Rocking the steering wheel gently back
and forth while turning the ignition key to MAR unlocks
the steering wheel.
• 3. PANEL INDICATORS
INSTRUMENT DISPLAY PANEL
3. These are the instrument panel warning LED indicators
for all FIAT Tipo/Tempra models. Your vehicle will only
have Panel Indicators relevant to your particular car.
• 4. ELECTRONIC CHECK PANEL
4. The electronic check panel is not fitted to models
with basic trim.
IMPORTANT NOTE: The check panel will not
indicate if the tail light fuses blow at the same
time, or if there is a circuit failure within the panel
display.
SIDE AND HATCHBACK DOORS
When the ignition key is at MAR, the check panel LEDs
g, h, i, I, m and n monitor the light bulbs and fuses.
LEDs a, b, c, d, and e monitor incomplete closure of
the side doors and hatchback.
• Never remove the key when the car is moving.
If you do, the steering wheel will lock the first
time you turn it.
• If the ignition lock has been tampered with or
shows any sign of damage (e.g. attempted theft),
have the lock checked at your nearest FIAT
Service Centre.

SWITCHING OFF THE ALARM
1C. Some models
are fitted with an
alarm exclusion
switch, which can
be found inside
the glove
compartment. If
the alarm is faulty
or the remote control batteries are flat:

IMPORTANT NOTE: Take care not to allow any dirt or grit
to get into the gearbox.
• Job 19. Check driveshaft gaiters.
45
B INSIDE INFORMATION: Make sure you have a 10 mm
Allen key that will fit, before you start. There's very little
room between gearbox and subframe. B
Q Job 17. Check auto, transmission fluid level.

The
automatic transmission fluid level should be checked with

the
car on level ground and the engine at normal running
temperature
-
the car should have been driven for about 4
miles. The level is checked by means of a dipstick next to the
battery.
IMPORTANT NOTE: i) It is especially important that the
fluid is at the correct level. If the system needs regular
topping up because of leaks, fix them as rapidly as
possible or have your FIAT dealer check the system,
ii) Wipe the dipstick only with a lint-free rag to avoid
clogging up transmission valves. Keep dirt out!
18B. The filter is
secured by one
central screw.
Undo this and pull
the filter down,
detaching its upper
fluid pipe in the
process. Remove
the filter, discard it
and fit the
replacement. Refit
the sump, using a
new gasket and
non-setting gasket
sealer.
Replace the drain plug and fill the gearbox through the
dipstick tube. {See Job
17.)

19A. Grasp and turn the
inner drive-shaft and
gaiters, checking for signs
of gaiter splitting or
damage that could allow
grease out or
-
worse still

-
water in. Ensure the
gaiter clips are secure.
Q INSIDE INFOR-
MATION: Inners tend to
leak, putting an oil
stain on the shaft, as
here. You can buy a
FIAT repair kit, with
bearing and
replacement gaiter, to
repair the leak. This
involves removing the
drive shaft
-
see
Chapter 6, Repairs
and Replacements. B
19B. Check the outer
gaiter as well. This moves
over a greater range and
is more prone to damage
and splits.
IMPORTANT NOTE:
Change a split, or
damaged gaiter as soon
as possible
-
preferably
before using the car
again.
If
necessary,
fresh Tutela CVT should be poured in through

the
dipstick tube, using a funnel in the tube or by using ATF

from
a dispenser with a small spout. You may have to leave

the fresh
oil to clear the tube before seeing a clear dipstick
reading.
G Job 18. Replace auto, transmission fluid and
filter.

As well as
Tutela CVT fluid, you will need a new, sump
gasket
and
a new gearbox oil filter, from your FIAT dealer. The
filter
should
be changed every time the oil is replaced.

18A.
Always drain the

fluid when
the trans-
mission
is
warm, such as

after a
run. Raise the

front
of the car on

ramps,
so the fluid

drains well
from the

drain
hole (C) at the rear
under-side of the 'box.

Remove
the drain plug

with an
Allen key or hexagonal socket adaptor, and allow the

fluid to
drain into a container beneath the transmission
-
allow

ten
minutes for complete drainage.
Underneath the car, remove the 13 transmission sump bolts.
H INSIDE INFORMATION: The sump is easily distorted,

so,
when refitting, tighten all bolts progressively and
evenly to the recommended torque
-
see Chapter 3,
Facts and Figures. B

17.
Check the level with the
engine idling and the gear
selector in the 'P' (PARK)
position. Pull out the dipstick

(A),
wipe it clean with paper
kitchen towel, re-insert it and
check the level. The upper

and
lower marks on the dipstick represent minimum and
maximum acceptable fluid levels.

Job 8. Automatic gear selector
control cable - replacement.
• Step 4:
Release the
outer cable
centring bush
from its
housing in the
gearbox.
• Step 5: H INSIDE INFORMATION! To
do this, you will have to make a simple
tool as shown here. There is no FIAT
'special tool'
-
each dealer has to make
this one himself! Use the tool to push
lightly upwards, so that the cable
centring bush (illustration Job
6-4

arrowed) comes out of its seat. B
• Step 6: Fit the new cable in the reverse
order. Use a new gasket when refitting the
sump.
IMPORTANT NOTE: Readjust the cables if
necessary. See Jobs 7 and 8.
Q Step 7: Refill the transmission with
automatic transmission fluid. See Chapter
3,
Facts and
Figures.
Job 7. Kickdown cable (automatic
transmission) - adjustment.
Refer to the illustrations in Job 6.
Q Step 1: Check that the slow running speed is correct and
the accelerator cable is correctly adjusted, with just a small
amount of slack.
Q Step 2: Disconnect the kickdown cable from the idler
pulley and ensure that it is perfectly free in its operation.
• Step 3: With the selector lever in 'P', start the engine and
let it idle.
Q Step 4: Pull the inner cable by hand until resistance is felt,
caused by the compression of the valves. The cable end should
now line up with its locating slot in the idler pulley
-
if not,
adjust nuts (7) and (8).
[_l Step 5: Reconnect the cable and then switch off the
engine.
• Step 6: Check that when the accelerator pedal is hard
down, there is
1
mm of further movement left on the
kickdown cable, otherwise, make further adjustments on nuts
(7) and (8).
Refer to illustration Job 6, Step 3.
• Step 1: Raise the car and support it securely on axle stands.
• Step 2: Remove the cover from the gear selection
mechanism and familiarise yourself with the drawing referred
to here.
Q Step 3: Manually select the 'P' (park) position, using the
lever beneath the gearchange (see illustration Job
6-3,
part
6).

• Step 4: Disconnect the cable from the selector eyelet (3)
and detach from the slot in the front end of the bracket (5).
Q Step 5: Disconnect the inner cable from the gearlever (6)
and release the outer casing from its gearbox mounted
bracket (7). Remove the cable.
Q Step 6: Ensure that 'P' (park) is still engaged by moving
the gearlever (6
-
beneath the car) fully rearward.
IMPORTANT NOTE: When 'Park' is properly engaged you
will not be able to turn both front wheels in the same
direction at the same time. This is because the trans-
mission should be 'locked' when 'park' is engaged.
• Step 7: Connect the new cable at the bracket (7) and
then at the bottom of the gear lever (6).
• Step 8: Feed the other end of the cable through to the
inside of the car and fix the outer casing into the slot in
bracket (5).
• Step 9: Put the interior selector lever (2) in the 'P' (park)
position and with the inner cable taut, check that the eyelet
(3) aligns perfectly with the selector pin.
• Step 10: If necessary, slacken the adjustment nut (4) and
adjust the position of the eyelet (3) accordingly. Fit the eyelet
to the pin and tighten the nut (4).
• Step 11: Check that the gears engage in their correct
positions on the selector indicator.

• Now that you have completed the
installation, and BEFORE USING THE
VEHICLE ON THE ROAD, carry out the
following check:
• The engine should only start when you have selected
either 'P' (park), or 'N' (neutral).
• The gear lever selector positions should agree with
those indicated on the display panel.
• When 'R' (reverse) is selected, the reverse light
should come on. With the ignition switched off, the
buzzer should sound if any position other than 'P'
(park) is selected.

Job 6-5

gjpjgjjl 'READING' YOUR SPARK PLUGS
Champion explain how the condition of spark plug firing ends can act as a guide to the state of tune and general condition of the engine. The examples shown are assumed to be the correct grade for the engine.
NORMAL
Core nose lightly coated with grey-brown deposits. Electrodes not burning unduly
-
gap increasing by about 0.01 mm every 1,000 miles approximately (with the use of unleaded fuel). Spark plugs correct for engine.
OIL FOULING
Deposits can short-circuit firing end, weakening or eliminating spark. Causes: worn valve guides, bores or piston rings, or while new engine is running-in. Replace spark plugs. Cure oiling problem.
SPLIT CORE NOSE
(May first appear as hair-line-crack). Probably caused by: Over-advanced ignition timing. Faulty distributor advance mechanism. Use of low octane fuel. Weak mixture. Manifold air-leaks. Cooling system problems. Incorrect gap-setting technique.
HEAVY DEPOSITS
Possible causes: Fuel or oil additives. Excessive upper cylinder lubricant. Worn valve guides. Unvarying speed (stationary engine). Replace spark plugs.
OVERHEATING
Likely causes are: Over-advanced ignition timing, or faulty distributor advance mechanism. Use of low octane fuel. Weak mixture. Discard spark plugs showing signs of overheating, and cure the cause.
CARBON FOULING
Look for dull black sooty deposits. (Unleaded fuel carbon fouling can appear similar to oil fouling). Deposits can short circuit the firing end, weakening or eliminating the spark. Check for: Over-rich mixture, faulty choke or clogged air filter. Replace spark plugs.
INITIAL PRE-IGNITION
Caused by serious overheating. Causes are those listed for overheating, but may be more severe. Corrective measures are urgently needed before engine damage occurs. Discard plugs in this condition.
FACT FILE: CORRECT INSTALLATION
• Make sure seating areas are perfectly clean.
• Insert plug finger tight to seat. Ensure plug 'spins' freely.
• PLUGS WITH SEATING GASKET: Tighten to relevant torque setting.
• PLUGS WITH TAPER SEATS: Tighten a further l/16th turn ONLY - no further!
• Overtightening can damage cylinder head or make taper seat plugs impossible to remove.
