fuse box FIAT TEMPRA 1988 Service And Repair Manual

LUGGAGE COMPARTMENT LIGHT
7b. TIPO: Pull the lens
downwards to remove
it. Remove and replace
the 5W tubular bulb.
7c. TEMPRA SALOON:
From inside the boot,
lever the light unit out
of its slot with a screw-
driver. Remove and
replace the 5W tubular
bulb (A).
DASH BULBS
See Chapter 6, Repairs and Replacements for details of
instrument panel removal for access to its light bulbs. The
bulbs are a quarter-turn fit in the back of the panel.
FACT FILE: FUSES
• 7d. The fuse box is
found to the side of
the steering column.
Pull the lever
marked FUSE...
• ...and lower the fuse box.
• 7e. A symbol above each fuse tells you which circuit it
protects. Four spare fuses are located near the top of the
fuse box.

Fuses located on the auxiliary panel
The fuses protecting special devices (options, features of
special versions or devices with high power require-
ments) are on an auxiliary panel to the side of the fuse
box under the dashboard. It is much easier to remove
and replace auxiliary panel fuses if you first remove the
oddment tray and moulding fastened by 5 screws. The
panel also houses a number of relays:
20A Intake manifold heater (petrol engines).
20A Diesel fuel filter heater (diesel and turbo diesel
engines).
20A Headlight washer pump.
25A Front power windows.
25A Rear power windows.
10A Antilock braking system.
7.5A Low beam headlight dimming system (for countries
where headlights always need to be on.)
30A Radiator fan (diesel versions).
40A Radiator fan (turbo diesel versions with heater).
60A Radiator fan (turbo diesel versions with air condi-
tioning).
The arrangement of the fuses on the auxiliary panel
varies with the number and type of devices present.
The amperage is clearly marked on each fuse. ALWAYS
replace a blown fuse with one of the correct amperage.
NEVER 'fix' a fault by using a fuse of a higher amperage,
nor 'bridge' a blown fuse
-
it could cause a fire!
7f. When a fuse is 'blown'
its conductor wire (A) has
a gap in it.
If a fuse blows, find out
why and put it right
before fitting a new fuse.

FACT FILE: FUSES contd. 7h. CERTAIN TIPO MODELS: Other
fuses are i) a set of three fuses (15A, 30A
and 40A) protecting the air conditioning,
when fitted, located in the engine bay,
near the horns (A). Press in the two sides
(arrowed) to remove the cover.
And ii) there is a 60A
fuse, located near the
fuse box, protecting
the fan on Diesel
vehicles.
7i. On latest vehicles,
there are two 10A
fuses (a) protecting
the electric petrol
pump and the
Lambda sensor
preheater. Remove
the screws (arrowed)
and the cover.
7g. TEMPRAS WITH
AIR CONDITIONING
30A The Air conditioning
system fuse is housed on
a bracket on the engine
compartment bulkhead.
The following two fuses
are located under the
front crossmember near
the right headlight.
3A High-speed radiator fan relay.
7.5A Electromagnetic air conditioner compressor clutch.
The relays housed near the fuses are part of the air
conditioner circuit.
IMPORTANT NOTE: Replace the sealed cover carefully
after changing a fuse. Ensure the gasket is correctly
positioned and the screws are fully tightened.
PART B: ENGIIME AND COOLING SYSTEM
Q Job 8. Change engine oil and filter.
SAFETY FIRST!
• Refer to the section on ENGINE OILS and RAISING

THE
CAR SAFELY in Chapter f, Safety First! before

carrying
out this work.
• You must wear plastic gloves when changing the oil.

Used
engine oil can severely irritate the skin and
is
carcinogenic.
Used diesel engine oil is an even greater

health
hazard.
•
Oil
drain plugs are often over-tightened, so take

care
that the spanner does not slip.

Take
care that the effort needed to undo the drain

plug
doesn't tip the car off its supports
-
remember to

use
wheel
chocks!

rtj&^si ' # °nly dram theu 0,7 fr°m a ff (y warm engine
-
but not
so

hot that the oil can scald!
• Allow the oil to drain for at least ten minutes before
replacing the sump plug.
• You can use this time by renewing the oil filter.
IMPORTANT NOTE: The plug is a taper-fit and can
become very tight, necessitating the use of a long drive-
bar for its removal.
H INSIDE INFORMATION: On side-mounted drain holes,
as the oil empties, the angle of 'spurt' will change, so be
prepared to move the container. E3

8A. The
sump drain

plug is on
the
under-side of the

sump on
petrol
engines, and on the

side
of the sump
(timing belt end of
engine) on the

diesel.
The plug has

a
recessed
hexagonal head and you will need either a sump plug
spanner, a large Allen key, or a 'Hex' headed socket fitted to a

socket
wrench.
8B. Once the initial
tightness of the
plug has been
released, unscrew
the last few turns
by hand, holding
the plug in place
until the threads
have cleared, then
withdrawing it
smartly to allow oil to flow into the receptacle beneath.
expert22
8C. On all engines,
including diesel, the
oil filter is mounted
low on the front of
the engine block,
towards the timing
belt. Use a strap or
chain wrench to
unscrew the old
filter. Note that
there may be a lot of oil spilt as the filter seal is broken, so
keep the drip tray beneath it.
