coolant temperature FIAT TEMPRA 1988 Service And Repair Manual

Fluid levels (if included) are monitored by LEDs f, o and
p, indicating the levels of the fluid reservoirs.
A red LED illuminates at the position on the check panel
corresponding to a side door or a hatchback/tailgate
that is not properly closed.
SIDE AND TAIL LIGHTS
When the side and tail lights are turned on, the check
panel monitors the light bulbs, fuses and circuits.
• LED g monitors the front side lights.
• LED i monitors the tail lights.
If one of the two fuses protecting the following bulbs
blows, LEDs g, i, and m illuminate.
NUMBER PLATE LIGHTS
• LED m indicates when one or both of the number
plate light bulbs have burnt out.
REAR FOG LIGHTS
• When the fog-guard lights are turned on, LED h
monitors the light bulbs.
• When the fuse blows or a circuit malfunction occurs,
LED h illuminates, but not the panel indicator.
STOP LIGHTS
If one or both stop lights burn out, the fuse blows or a
circuit malfunction occurs, LED I or n illuminates when
braking.
• LED n monitors the left stop light.
• LED I monitors the right stop light.
If both bulbs burn out at the same time or brake pedal
switch malfunction occurs, both LEDs I and n
illuminate.
ENGINE OIL LEVEL
• LED f illuminates when the engine oil level is low (key
at MAR,engine not running).
The oil level monitoring system does not operate when
the engine is running. If the oil level warning LED
illuminates when driving, a circuit sensor malfunction
has occurred.
When starting the car on a hill or within 10 minutes of
switching off the engine the warning light may
illuminate (event will be stored in system memory). Start
the engine again on level ground to ensure the oil level
is sufficient.
COOLANT
A low coolant level is indicated by LED o (key at MAR).
The LED also illuminates when a sensor or circuit
malfunction occurs.
WINDSCREEN AND REAR SCREEN WASH LEVELS
• LED p illuminates (key at MAR) when the level in the
windscreen or rear screen wash reservoirs are low.
• The LED also indicates when a circuit or sensor
malfunction occurs.

B INSIDE INFORMATION! The cylinder head gasket is of
the special 'ASTADUR' type and polymerises during
engine use, becoming much harder. It should only be
removed from its wrapping immediately before fitting
and then should be kept free of contamination by oil,
grease or water. Fit only between clean and dry cylinder
head and block surfaces. B
• Step 3: Discard the old gasket and thoroughly clean the
cylinder block mating surface and dry off. Make sure that the
bores are free of gasket particles.
B INSIDE INFORMATION! It is important to be sure that
all the cylinder head bolt holes in the block are clear
right down to their bottoms. The bolts and washers
should be cleaned, lubricated with engine oil and then
drained for at least 20 minutes before fitting. B
• Step 4: Clean the cylinder head, taking care not to gouge
the aluminium surface
-
use a straight edge that isn't too
sharp.
Q Step 5: Place the new gasket on the cylinder block with
the word 'ALTO' facing upwards.
• Step 6: Lower the head into position and screw all the
bolts in finger tight.
LI Step 7: Note the numbered tightening order of the ten
main cylinder head bolts. Using a suitable torque wrench,

INFORMATION!
Refer to the illus-
tration and note
that the piston
should be fitted
to the connecting
rod so that when
viewed from the
timing end the
crown lift (1) is
on the right
hand/injection
pump (2) side. At
the same time,
the bore numbers
stamped on the connecting rod (3) should face left, the
opposite side. The piston pins are an interference fit in
the pistons and can be tapped into position using an
ordinary drift and secured with circlips. H
Refer to Job 6. Steps 11 to

• Step 19: Bleed the fuel system. See PART F: FUEL AND
EXHAUST
Q INSIDE INFORMATION! Bleeding the fuel system
involves turning the engine on the starter. This should
allow it to gain oil pressure before 'firing up', but check
that the oil light has gone out as soon as the engine
starts. H
Q Step 20: Allow the engine to run at 'fast idle' until it
reaches working temperature and switch off. Allow it to cool
and check the oil and coolant levels and look for any leaks.
Q Step 21: Avoid over-rewing or overloading the engine
during its settling down period of 600 miles. We recommend
an oil and filter change at this mileage
