1988 FIAT TEMPRA drain bolt

Thanks
are due to the excellent, knowledgeable and helpful staff at FIAT main dealers, Ryauto of Amblecote, in the West
Midlands for supplying vehicles and for their assistance with this chapter. In particular, thanks are due to the efficient Maurice
Hough, Service Manager, the experienced Foreman, Tony Morris, and young demon mechanic, Matthew Worsfold.
Some of the suggested inspection/replacement intervals may not correspond to those shown in the original handbook. The suggested
schedule, based on FIAT'S recommendations, takes into account the age of the vehicle and the annual MoT test in the UK.
In practice, because of the split between (mainly) 12 month/9,000 mile and 18 month/13,500 mile intervals, you will need to
service your Tipo or Tempra at most, if not every, 6 month interval.
IMPORTANT NOTE: Each service should be carried out at EITHER the recommended mileage OR the recommended time
interval, whichever comes first.

8D. To prevent the rubber sealing
ring on the new filter from
buckling or twisting out of shape
while tightening, smear it with
clean oil.
8E. Screw the new filter onto the
stub by hand. When the rubber
sealing ring contacts its seat,
continue to turn the
filter a further 3/4
of a turn, by hand
only. Over-tight-
ening the filter
makes it difficult to
remove at the next
oil change and can
buckle the seal,
causing a leak.
E3 INSIDE INFORMATION: It isn't necessary to use
excessive force when refitting the sump plug. Simply grip
the spanner (no need for an extension, now!) so that the
thumb rests on the spanner head, limiting the amount of
leverage that can be applied. Use firm pressure only.
Before refitting the plug, wipe around the drain hole
with a piece of clean cloth to remove any dirt. II
8F. Pour in the correct quantity of
Selenia engine oil (see Chapter
3, Facts and Figures) and check
the level against the dipstick.
Note that the empty oil filter will
cause the level to drop slightly
when the engine is started and
the oil flows into it. Before using
the car, run the engine for two
minutes, turn off, leave to stand
for a few minutes and then
recheck and correct the oil level.

easily damage it.
Use a spatula to push through the soft joint until the
gasket/cover comes free. D
10C. E3 INSIDE
INFORMATION:
The oil level inside
the housing is
above the level of
the bottom of the
cover plate on
these engines.
Try: i) raising the
front of the car as
high as safely possible, so that oil drains out of the back
of the housing; ii) stuffing cloths beneath the opening
and have more ready, for mopping up; iii) being ready to
clean off the front of the engine with degreaser, when
the job is finished. D
10D. The valve
clearance is
measured directly
beneath the cam
and must be
checked when the
high point of the
cam (arrowed) is
pointing directly
upwards and away
9. Check the
condition of the
breather hose from
the valve cover or
cam cover to the air
cleaner. If the pipe
has become
blocked or
damaged, replace
it, transferring the
flame trap from inside the old pipe to the new one. On some
models, you will have to remove the air filter housing to get at
the crankcase ventilation pipe beneath. Note this type of
spring clip
-
use pliers to slacken-off when removing or re-
fitting.
Try different feeler gauge thicknesses until you find one that's
a tight sliding fit between cam and follower. Make a written
note of each clearance starting with number
1
at the timing
belt end of the engine.
from the cam follower.

IMPORTANT NOTE: Take care not to allow any dirt or grit
to get into the gearbox.
• Job 19. Check driveshaft gaiters.

B INSIDE INFORMATION: Make sure you have a 10 mm
Allen key that will fit, before you start. There's very little
room between gearbox and subframe. B
Q Job 17. Check auto, transmission fluid level.

The
automatic transmission fluid level should be checked with

the
car on level ground and the engine at normal running
temperature
-
the car should have been driven for about 4
miles. The level is checked by means of a dipstick next to the
battery.
IMPORTANT NOTE: i) It is especially important that the
fluid is at the correct level. If the system needs regular
topping up because of leaks, fix them as rapidly as
possible or have your FIAT dealer check the system,
ii) Wipe the dipstick only with a lint-free rag to avoid
clogging up transmission valves. Keep dirt out!
18B. The filter is
secured by one
central screw.
Undo this and pull
the filter down,
detaching its upper
fluid pipe in the
process. Remove
the filter, discard it
and fit the
replacement. Refit
the sump, using a
new gasket and
non-setting gasket
sealer.
Replace the drain plug and fill the gearbox through the
dipstick tube. {See Job
17.)

19A. Grasp and turn the
inner drive-shaft and
gaiters, checking for signs
of gaiter splitting or
damage that could allow
grease out or
-
worse still

-
water in. Ensure the
gaiter clips are secure.
Q INSIDE INFOR-
MATION: Inners tend to
leak, putting an oil
stain on the shaft, as
here. You can buy a
FIAT repair kit, with
bearing and
replacement gaiter, to
repair the leak. This
involves removing the
drive shaft
-
see
Chapter 6, Repairs
and Replacements. B
19B. Check the outer
gaiter as well. This moves
over a greater range and
is more prone to damage
and splits.
IMPORTANT NOTE:
Change a split, or
damaged gaiter as soon
as possible
-
preferably
before using the car
again.
If
necessary,
fresh Tutela CVT should be poured in through

the
dipstick tube, using a funnel in the tube or by using ATF

from
a dispenser with a small spout. You may have to leave

the fresh
oil to clear the tube before seeing a clear dipstick
reading.
G Job 18. Replace auto, transmission fluid and
filter.

As well as
Tutela CVT fluid, you will need a new, sump
gasket
and
a new gearbox oil filter, from your FIAT dealer. The
filter
should
be changed every time the oil is replaced.

18A.
Always drain the

fluid when
the trans-
mission
is
warm, such as

after a
run. Raise the

front
of the car on

ramps,
so the fluid

drains well
from the

drain
hole (C) at the rear
under-side of the 'box.

Remove
the drain plug

with an
Allen key or hexagonal socket adaptor, and allow the

fluid to
drain into a container beneath the transmission
-
allow

ten
minutes for complete drainage.
Underneath the car, remove the 13 transmission sump bolts.
H INSIDE INFORMATION: The sump is easily distorted,

so,
when refitting, tighten all bolts progressively and
evenly to the recommended torque
-
see Chapter 3,
Facts and Figures. B

17.
Check the level with the
engine idling and the gear
selector in the 'P' (PARK)
position. Pull out the dipstick

(A),
wipe it clean with paper
kitchen towel, re-insert it and
check the level. The upper

and
lower marks on the dipstick represent minimum and
maximum acceptable fluid levels.

Q INSIDE INFORMATION! • Before removing the
cylinder head, make sure the engine is stone cold.
• Undo the cylinder head bolts strictly in the order laid
out in Step 18.
• These precautions help to prevent cylinder head
distortion.
• The new cylinder head gasket should stay in its
packaging until required, to avoid contamination by oil

or grease.
B
FACT FILE: SPECIAL TOOL PROBLEMS
SOLVED!
• It is possible to remove and replace the
cylinder head complete with the camshaft
housing - but it is very difficult without
FIAT's special cranked tool to get round the camshaft
housing.
• You CAN undo the bolts with a ring spanner, but you
CAN'T torque them down properly again!
• Because the gasket between the housing and the head could
also be suspect, we strongly recommend that you do it 'our'
way, by removing the camshaft housing even though you will
have to re-set the valve clearances.

SAFETY FIRST! • Step 7:
Disconnect the
electrical leads from
the following: the
inlet manifold
• Step 2: Disconnect both battery leads, negative
terminal first.

Q Step 27: Remove the old gasket.
IMPORTANT NOTES: • Here, we show how to refit the
head and camshaft housing, separated. The head
complete with housing cannot be torqued down
correctly without the use of FIAT's special, cranked
spanner for use on the semi-hidden head bolts.
• The valve clearances will have to be re-set. See Job 7.
Clean the block and cylinder head mating surfaces with a
straight edge, taking particular care with the light alloy head.
Any gouging of the metal could prove very expensive to have
put right!
