check engine light FIAT TEMPRA 1988 Service And Owner's Manual

&CASU / # Q StGP 101 The ValV6S i* (/ should slide freely out of
their guides. Any resistance
may be caused by a build up of carbon, or a slight burr
on the stem where the collets engage. This can usually
be removed by careful use of fine wet-or-dry paper,
allowing you to
withdraw the valves
without scoring their
guides. Keep the valves
in their correct order by
wrapping a numbered
piece of masking tape
around each stem.
• Step 12: Clean the
carbon from the valves with
a rotary wire brush and
wash them in paraffin.
Wash the valve springs,
caps, seats and collets and
dry.
/ • Before grinding-in the
valves, clean the tops of the
valve heads back to shiny
metal. Now the sucker on the end of your valve
grinding stick won't keep falling off when you grind-
in the valves!
head. Don't hesitate to seek the advice of your local agent if
you have any doubts.
• Step 14: Examine the valve seats for pitting or burning.
Also, check the valve seats in the cylinder head. Small pits can
be removed by grinding the valves onto their seats. The seats
in the cylinder head will have to be recut (again, by your local
FIAT agent if the pitting is too deep), and new valves fitted.
B INSIDE INFORMATION! These cylinder heads use
hardened valves and seats for use with unleaded petrol.
We advise you to consult your FIAT agent or engine
specialist for machining if anything other than light
valve grinding is required. B
FACT FILE: VALVE GRINDING
• Step 15: Apply a small quantity of
coarse grinding paste evenly round the valve
seat. A valve grinding stick with a suction pad
slightly smaller than the valve head should
be selected. Put a dab of moisture onto the suction pad and
press the grinding stick to the first valve.
• Step 16: Lower
the valve stem into its
guide and, holding the
grinding stick
between the palms of
your hands, rub your
hands together (like a
bushman making a
fire), rotating the
valve and grinding the
two seats together.
Lift the valve
regularly, say every
ten or so turns, to
allow the grinding
paste to be redis-
tributed. When you
can feel the paste
wearing smooth,
remove the valve and
wipe all the surfaces
clean. A complete ring
of grey contact area
should be visible on
the valve head and its
seat in the cylinder head. If necessary, start off with coarse
paste to remove the deeper pits, and finally use fine paste to
obtain a smooth finish.
• Make sure that no paste is allowed to enter the guide. This
would cause a lot of wear to the valve stem and guide.
• A narrow contact band means more seat pressure and
longer life. A wide band allows rapid valve burning.
• A complete ring of grey contact area should be visible on
the valve head and its seat in the cylinder head.
• If necessary, start off with coarse paste to remove the
deeper pits, and finally use fine paste to obtain a smooth
finish.
• If pitting is too bad, you could have the valve face and the
valve seats resurfaced or, in worst cases, the valve and/or valve
seat (in the cylinder head) will have to be replaced.
• Consult your FIAT dealer or engine specialist if in doubt.
LJ Step 11: The cylinder head is made of light alloy and is
easily damaged when being cleaned. Use a rotary wire brush
for the combustion chambers and ports, but no sharp objects
such as screwdrivers should be used. The machined surfaces
must have all traces of old gasket removed by use of a straight
edge. Then wash down with paraffin to remove old oil and
dirt and dry with clean rag.
At all costs, avoid gouging
the cylinder head. This can
be very expensive to have
put right.
• Step 13: The cylinder
head can be checked for
distortion by use of a
straight edge and feeler
gauge. At the same time check for excessive corrosion. If you
are in doubt, or if the old gasket had blown, have the cylinder
head refaced by your FIAT agent or engine specialist. The
valves should be checked for side movement in their guides.
Anything but the very slightest tells you that the valve guides
are in need of replacement. Your local FIAT agent or engine
specialist should do this job. Examine the valve seats for
pitting or burning, also check their mating seats in the cylinder

• Step 30: Fit
the crankshaft
pulley and
tighten. See
Chapter 3,
Facts and
Figures.
• Step 31: Fit the
water pump and
distribution pipe.
• Step 32A: Refit the
flywheel. Do not unbolt the
TDC sensor (1) from the oil seal
housing at its mounting plate
bolts
(2)
unless it is essential to
do so.
• Step 32B: If
the sensor
mounting plate has
to be disturbed, you
will need the FIAT
special tool illus-
trated here (inset) in
order to reposition it
correctly. Position
the timing mark on
the crankshaft
pulley with the zero
degrees mark on the outer timing belt cover (and double
check that the timing mark on the flywheel
-
rubber bung
removed
-
is aligned at zero degrees).
With the bracket fitted to the oil seal housing, fit the FIAT
special tool onto the bracket in place of the sensor with a slot
in the tool fitting exactly over the TDC pin on the flywheel.
When everything is lined up, position the bracket accurately
and tighten the bolts. Remove the tool and refit the sensor.
IMPORTANT NOTE: During assembly, a shear-bolt will
have been fitted to prevent accidental movement of the
bracket. If you need to undo it, you will need to drill it
out and you should replace it with a new one obtained
from your FIAT dealership.
• Step 33: Refit the clutch. See PARTB: TRANSMISSION,
Job 4.
Q Step 34: Refit the fuel pump and pushrod using new
gaskets on both sides of the spacer block, 0.3 mm thick
between the spacer and the engine and 0.7 mm between the
spacer and the pump. See PART F: FUEL AND EXHAUST for
information on setting the pump position.
• Step 35:
Lubricate the sealing
ring and screw on a
new oil filter.
• Step 36:
Before refitting the
distributor, (see
PART D: IGNITION)
refit, if necessary,
the oil pump drive
gear.
• Step 37: Refit
all remaining
auxiliary compo-
nents (including the
oil vapour recovery
device, shown here),
using new gaskets
as necessary and
referring to
Chapter
3,
Facts
and Figures for the
torque settings.
Q Step 38: Reconnect the engine to the transmission. See
Job 11.
Q Step 39: Refit the complete unit to the car. See Job
9.

• Step 40: fl INSIDE INFORMATION! Before fitting the
spark plugs and with a fully charged battery, turn the
engine on the starter until the oil warning light goes
out. This primes the lubrication system and gives more
immediate oil pressure on initial start up after overhaul-
a critical time in the life of an engine. B
• Step 41: Fit the spark plugs and start the engine
-
this
might take a few seconds more than normal on the initial start
up.
• Step 42: Allow the engine to warm up on fast idle
until
it
reaches working temperature and then slow it down to its
normal speed (if adjustable

EXHAUST)

CRANKSHAFT
• Step 1: TURBO ONLY: Before fitting the crankshaft,
install the four piston sprays (a) and stake the retaining plates
(arrowed).
Q Step 2: Locate the main bearing shells so that they are
firmly seated and their tabs engage with the slots in the
journal webs.
• Step 3: Apply some grease to the smooth side of the
thrust washers and 'stick' them in position on both sides of
the rear main bearing web (at the flywheel end).
• Step 4: Oil the shells liberally with fresh engine oil and
lower the crankshaft into position.
• Step 5: Fit the remaining halves of the shells into the
bearing caps. Oil the journals and position the caps the right
way round and in the correct order.
• Step 6: Screw the bolts in finger-tight and check that the
crankshaft rotates freely and smoothly.
Q Step 7: Tighten the bolts evenly and progressively until
the specified torque setting is reached, see Chapter
3,
Facts
and Figures. Check again that the crankshaft rotates
smoothly.
• Step 19:

Job 24. Diesel engine -
reassembly.
Before starting work, read the notes at the beginning of
Job 6 for petrol engine reassembly
-
the checks and
preparation being basically the same for diesel engines.
H INSIDE INFORMATION! TURBO ENGINES ONLY. The
piston cooling sprays must be checked for serviceability
before refitting. Each spray contains its own valve which

must
open at between 1.25 and 1.75 bar. Below this
figure could cause excessive oil burning and low oil
pressure. Above this figure might result in the piston
overheating and its subsequent failure. Have your FIAT
dealer carry out this check, and replace any faulty units if
necessary. Q
• Step 9: Fit new oil
seals to the two seal
carriers.
• Step 10: Fit the
rear oil seal carrier (with
its new seal), using a
new gasket. Lubricate
the seal (illustration Job

24-9,
part b) and
lightly oil the gasket (a).
• Step 11: Position Nos. 1 and 4 crank pins at Top Dead
Centre (TDC), then fit the flywheel with its TDC mark facing
the cylinder head surface. Screw in the fixing bolts and tighten
to their specified torque. See Chapter
3,
Facts and Figures
Job 23-21
Q Step 8: Turn and lever the crankshaft tight against the
timing end and check the crankshaft end float by using a
feeler gauge between the thrust washer on the timing side of
the web and the crankshaft. Thicker washers are available if
required. See Chapter
3, Facts and Figures.

U Step 12: Fit a new seal to the front cover/oil pump
assembly, unless a new pump is being fitted, and install with a
new gasket, lightly oiling both gasket and seal. Align the cover
with the sump support plate.
PISTON CONNECTING RODS ASSEMBLIES
• Step 13:
H INSIDE
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
18,
for installation procedures.
Q Step 14: Refit the oil pump pick-up and return pipes.
• Step 15: Refit the sump using a new gasket. Check that
the drain plug is tight.
• Step 16: Complete the reassembly by fitting all the
external components in the reverse order of removal. Refer to
Job
15
for cylinder head refitting.
• Step 17: Reconnect the engine to the transmission. See
Job
22

• Step 18: Refit the complete unit to the car. See Job
19

• 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

control cable - replacement.
• Step 4:
Release the
outer cable
centring bush
from its
housing in the
gearbox.
• Step 5: H INSIDE INFORMATION! To
do this, you will have to make a simple
tool as shown here. There is no FIAT
'special tool'
-
each dealer has to make
this one himself! Use the tool to push
lightly upwards, so that the cable
centring bush (illustration Job
6-4

arrowed) comes out of its seat. B
• Step 6: Fit the new cable in the reverse
order. Use a new gasket when refitting the
sump.
IMPORTANT NOTE: Readjust the cables if
necessary. See Jobs 7 and 8.
Q Step 7: Refill the transmission with
automatic transmission fluid. See Chapter

Q Step 1: Check that the slow running speed is correct and
the accelerator cable is correctly adjusted, with just a small
amount of slack.
Q Step 2: Disconnect the kickdown cable from the idler
pulley and ensure that it is perfectly free in its operation.
• Step 3: With the selector lever in 'P', start the engine and
let it idle.
Q Step 4: Pull the inner cable by hand until resistance is felt,
caused by the compression of the valves. The cable end should
now line up with its locating slot in the idler pulley
-
if not,
adjust nuts (7) and (8).
[_l Step 5: Reconnect the cable and then switch off the
engine.
• Step 6: Check that when the accelerator pedal is hard
down, there is
1
mm of further movement left on the
kickdown cable, otherwise, make further adjustments on nuts
(7) and (8).
Refer to illustration Job 6, Step 3.
• Step 1: Raise the car and support it securely on axle stands.
• Step 2: Remove the cover from the gear selection
mechanism and familiarise yourself with the drawing referred
to here.
Q Step 3: Manually select the 'P' (park) position, using the
lever beneath the gearchange (see illustration Job
6-3,
part
6).

• Step 4: Disconnect the cable from the selector eyelet (3)
and detach from the slot in the front end of the bracket (5).
Q Step 5: Disconnect the inner cable from the gearlever (6)
and release the outer casing from its gearbox mounted
bracket (7). Remove the cable.
Q Step 6: Ensure that 'P' (park) is still engaged by moving
the gearlever (6
-
beneath the car) fully rearward.
IMPORTANT NOTE: When 'Park' is properly engaged you
will not be able to turn both front wheels in the same
direction at the same time. This is because the trans-
mission should be 'locked' when 'park' is engaged.
• Step 7: Connect the new cable at the bracket (7) and
then at the bottom of the gear lever (6).
• Step 8: Feed the other end of the cable through to the
inside of the car and fix the outer casing into the slot in
bracket (5).
