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.

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.

WIRING DIAGRAMS
IMPORTANT NOTE: Not all of the components listed here
are fitted to all models.
IMPORTANT NOTES:
3. We have sometimes shown the wiring diagram for a
'highest' spec, model, in the knowledge that 'lower'
spec, models are usually similar with the deletion of
certain components.
1. There are several hundred FIAT wiring diagrams for
the whole TIPO range. This is a representative selection,
covering the majority of applications. However, in the
event that your car's details are not covered here,
consult your nearest FIAT dealer.
2 All of the following are Tipo wiring diagrams. Tempra
saloons and estates are essentially similar.
4. 'EEC Stage 2 Engines' In late 1994, Tipo 1.4 and 2 -
Litre and Tempra 1.6 MPI vehicles were modified to suit
new emission regulations. These changes were NOT only
engine-related. Vehicles covered by this manual are Tipo
1.4 (with engine code no. 836A4.000) and Tempra 1.6
(with engine code 159B9.000). See Page 27 for location
of codes.
