ad blue 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.

O 23. Have your assistant press down firmly on the brake pedal while you check the rear brake flexible hoses for bulges, splits or other deterioration.
o 24. Check the fuel tank for leaks or corrosion. Remember also to check the fuel filler cap
-
a correctly sealing filler cap is a part of the MoT test.
O 25. Examine the handbrake mechanism. Frayed or broken cables or worn mounting points, either to the bodywork or in the linkage will all be failure points.
o 26. Check each of the rear wheel
bearings as for the fronts.
o 27. Spin each rear wheel and check that neither the wheel bearings nor the brakes are binding. Pull on and let off the handbrake and check once again to make sure that the handbrake mechanism is releasing.
SAFETY FIRST!
• Only run the car out of doors.
• Beware of burning yourself on a hot exhaust system.
o 28. While you are out from under the car, but with the rear end still raised off the ground, run the engine. Hold a rag over the end of the exhaust
pipe and listen for blows or leaks in the system. You can now get back under the car and investigate further if necessary.
o 29. Check the exhaust system mountings and check for rust, corrosion or holes in the rear part of the system.
o 30. Check the rear brake back plate or calipers (as appropriate) for any signs of fluid leakage.
o 31. Check the insides and the outsides of the tyres as well as the tyre treads for damage, as for the front tyres.
PART D: EXHAUST EMISSIONS
This is an area that is impossible to
check accurately at home. However,
the following rule-of-thumb tests will
give you a good idea whether your car
is likely to fail or not.
H INSIDE INFORMATION: If you
feel that your car is likely to fail
because of the emission test, have
your MoT testing station carry out
the emission part of the test first so
that if it fails, you don't waste
money on having the rest of the
test carried out. Q
O 1. PETROL ENGINES BEFORE 1 AUGUST 1973 AND DIESEL ENGINES BEFORE 1 AUGUST 1979 only have to pass visible smoke check. Rev the engine to about 2,500 rpm (about half maximum speed) for 20 seconds and then allow it to return to idle. If too much smoke is emitted (in the opinion of the tester) the car will fail.
O 2.DIESEL ENGINES FROM 1 AUGUST 1979 The engine will have to be taken up to maximum revs several times by the tester, so make certain that your timing belt is in good condition, otherwise severe damage could be caused to your engine. If the latter happens, it will be your responsibility!
FACT FILE: VEHICLE EMISSIONS

PETROL
ENGINED VEHICLES WITHOUT
CATALYSER

Vehicles first used before 1 August 1973

• visual smoke check only.

Vehicles first used between 1 August 1973 and 31 July 1986

• 4.5% carbon monoxide and 1,200 parts per million, unburned
hydrocarbons.

Vehicles first used between 1 August 1986 and 31 July 1992

• 3.5% carbon monoxide and 1,200 parts per million, unburned
hydrocarbons.
PETROL ENGINED VEHICLES FITTED WITH
CATALYTIC

CONVERTERS
i

Vehicles first used from 1 August 1992
(K-registration on)

• All have to be tested at an MoT Testing Station specially equipped to
handle cars fitted with catalytic converters whether or not the vehicle
is fitted with a 'cat'. If
the
test, or the garage's data, shows that the
vehicle was not fitted with a 'cat' by the manufacturer, the owner is
permitted to take the vehicle to
a
Testing Station not equipped for
catalysed cars, if he/she prefers to do so (up to 1998-only). Required
maxima are
-
3.5% carbon monoxide and 1,200 parts per million,
unburned hydrocarbons. The simple emissions test (as above) will be
supplemented by a further check to make sure that the catalyst is
maintained in
good
and efficient working order.
• The tester also has to check that the engine oil is up to a specified
temperature before carrying out the test. (This is because 'cats' don't
work properly at lower temperatures
-
ensure your engine is fully
warm!)
DIESEL ENGINES'EMISSIONS
STANDARDS

• The Tester will have to rev your engine hard,
several times. If it is not in good condition, he is
entitled to refuse to test it. This is the full range of
tests, even though all may not apply to your car.

Vehicles first used before 1 August, 1979

• Engine run at normal running temperature; engine speed taken to
around 2,500 rpm (or half
governed
max. speed, if lower) and held for
20 seconds. FAILURE, if engine emits dense blue or black smoke for
next 5 seconds, at tick-over. (NOTE: Testers are allowed to be more
lenient with pre-1960 vehicles.)

Vehicles first used on or after 1 August, 1979

• After checking engine condition, and with the engine at normal
running temperature, the engine will be run up to full revs between
three and six times to see whether your engine passes the prescribed
smoke density test. (For what it's worth
-
2.5k for non-turbo cars; 3.0k
for turbo diesels. An opacity meter probe will be placed in your car's
exhaust pipe and this is not something you can replicate at home.)
Irrespective of the meter readings, the car will fail if
smoke
or vapour
obscures the view of other road users.
• IMPORTANT NOTE: The diesel engine test puts a lot of stress on the
engine. It is IMPERATIVE that your car's engine is properly serviced,
and the cam belt changed on schedule, before you take it in for the
MoT test. The tester is entitled to refuse to test the car if
he
feels that
the engine is not in serviceable condition and there are a number of
pre-Test checks he may carry out.
