required.
Q Step B13: Re-assemble and refit by following Steps A13

to
A18.
PART C: LATER FRONT AND REAR DOORS
IMPORTANT NOTE: We cover removal/replacement of
the electrically operated window mechanism. Removal
of the manually operated regulator mechanism is similar
in principle to the earlier type. See PART A: EARLY
FRONTDOORS
Q Step C1: Remove the door trim panel. See Job 11
Q Step C2: Remove
the transparent
covering from the door
panel and keep it in a
dust free place so that
it will re-stick easily
when refitted.
• Step C3: Undo
the four bolts
• Step C9:.... and withdraw the regulator, motor and guide
assembly from the door.
• Step C10: Refit in the reverse order of removal and
adjust the fit of the glass in the channels for smooth operation
without binding. The glass should then stay in any set
position.

B INSIDE INFORMATION! To avoid the need to 're-hang'
the door, it is best to remove the hinge pins rather than
unbolt the hinge from the body, unless necessary. B
PART A: DOOR REMOVAL.
LI Step A1: Remove the door lining by following the steps
outlined in the relevant part of Job 11.
• Step A2: Disconnect all the electrical cables from the
electrical components inside the door.

B INSIDE INFORMATION! As an alternative to steps A1
and A2 you can disconnect all the electrical plugs under
the dashboard, which have wires which go through to
the door. B
LI Step A3: Support the door using a trolley jack with a
wad of rag on its pad for protection.
LI Step A4: Remove the door restricter pin (inset and
arrowed) with FIAT tool 1878081000 or similar. With a helper
holding the door steady, undo the hinge pin bolts (arrowed),
and lift the door clear.

adjustment.
B INSIDE INFORMATION! Shims with a thickness of 1mm
are available from your FIAT dealer to fit under the door
lock striker, if necessary. B
PART C: DOOR HINGE ADJUSTMENT.
IMPORTANT NOTE: Have an assistant support the weight
of the door as the hinge bolts are slackened.
• Step C1: Support the car on axle stands and remove the
road wheel on the side to be worked on.
• Step C2: If
adjusting a front
door, remove the
front wheel arch
liner by undoing the
retaining studs and
screws. Rear doors
are adjusted with
the front door open.
B INSIDE INFORMATION: The bolts fixing the hinges to
the bodywork are very tight. Use a torque wrench or a
proprietary extension on your socket wrench when slack-
ening them. B

Remove the backrest
release trim in the
direction indicated
by the lower arrow.
• Step B5:
Remove the seat as
described in PART
A, Steps A1 and
A2.
—I Step B6: Turn the seat over and slide it as far forwards as
it will go on its runners to provide maximum slack on the
bowden cable.
O Step B7: Using a Torx key, available from a motor
accessory store, undo the bolt (see illustration Job
17-C2,

part 6) and release the pretensioner assembly
(17-C2,
part
4)

• Step C2:
• Position the support block (1) between the power unit (2)
and the seat bracket.
• Align the power unit (2) along the seat frame and secure it
with the screw (3) and washer, tightening to 6 to 8 Nm.
• Slide the lock (4) and buckle unit between the seat base and
adjusting bar and locate the lock in bracket (5). Fix the rear
end with the screw (6) and tighten to between 35 and 43 Nm.
• Step C3A: Align
the cable's white paint
spots with the securing
clips on the seat base.
The 5 door's seat cables

the seat centrally on
the runners and refit to
the car, taking care to
handle it as described
in Step B3.
SAFETY FIRST!
• • Step B2: Before
starting to remove the

withdraw the safety clip from its slot and position it on the
sensor frame cover. The unit is now operational.
PART D: 3 DOOR VERSION, REFITTING
IMPORTANT NOTE: Read SAFETY FIRST! Steps B2 and
B3.
• Step D2B: .. and
like this for height
adjustable version.
• Step D3: Now
follow Steps C4 and C5
to complete the job.
• Step D1:
• Position the support block (1) between the power unit (2)
and the seat bracket.
• Align the power unit (2) and secure it with screw (12),
washer and nut (4 and 5). Tighten to 6 to 8 Nm.
• Slide the lock (10) and buckle (9) between the seat base and
the adjusting bar.
• Locate the front of the lock unit (10) into the bracket (11)

cable run should
look like this for the
basic seat...
• Step 1: Undo the fixing bolts (a) and slide out the seat
cushion.
Q Step 2: Lower the back rest and prise out the buttons
fixing the rear compartment shelf to the backrest.
• Step 3: Disengage the catch (see illustration Step 1, part
b), undo the hinge bolts and withdraw the backrest.
Q Step 4: Refit in reverse order.
IMPORTANT NOTE: Split rear seats also have central
hinge brackets to be unscrewed.
Job 18. Headrest removal.
• Step 1: Raise the headrest as far as it will go.
• Step 2: Turn each of the support bars through 90
degrees. This releases the bar from their spring clips inside the
seat backrest.
Q Step 3: Lift out the headrest.
Q Step 4: After refitting, turn each support bar through 90
degrees and check that the spring clips have located in the
grooves at the lower end of each support bar.

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.

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.
