Please be sure to read the whole of this Chapter before carrying out any work on your car. 
SAFETY FIRST! 
You must always ensure that 
safety is the first consideration 
in any job you carry out. A 
slight lack of concentration, or 
a rush to finish the job quickly 
can easily result in an accident, 
as can failure to follow the 
precautions outlined in 
this manual. 
Be sure to consult the 
suppliers of any materials and 
equipment you may use, and 
to obtain and read carefully 
any operating and health and 
safety instructions that may 
be available on packaging or 
from manufacturers 
and suppliers. 
Raising the Car Safely 
ALWAYS ensure that the vehicle is properly supported when 
raised off the ground. Don't work on, around, or underneath 
a raised vehicle unless axle stands are positioned under 
secure, load bearing underbody areas, or the vehicle is driven 
onto ramps, with the wheels remaining on the ground 
securely chocked to prevent movement. 
NEVER work on a vehicle supported on a jack. Jacks are made 
for lifting the vehicle only, not for holding it off the ground 
while it is being worked on. 
ALWAYS ensure that the safe working load rating of any 
jacks, hoists or lifting gear used is sufficient for the job, and 
that lifting gear is used only as recommended by the 
manufacturer. 
NEVER attempt to loosen or tighten nuts that require a lot of 
force to turn (e.g. a tight oil drain plug) with the vehicle 
raised, unless it is safely supported. Take care not to pull the 
vehicle off its supports when applying force to a spanner. 
Wherever possible, initially slacken tight fastenings before 
raising the car off the ground. 
ALWAYS wear eye protection when working under the 
vehicle and when using power tools. 
Working On The Vehicle 
ALWAYS seek specialist advice unless you are justifiably 
confident about carrying out each job. The safety of your 
vehicle affects you, your passengers and other road users. 
DON'T lean over, or work on, a running engine unless it is 
strictly necessary, and keep long hair and loose clothing well 
out of the way of moving mechanical parts. Note that it is 
theoretically possible for fluorescent striplighting to make an 
engine fan appear to be stationary
 -
 double check whether it 
is spinning or not! This is the sort of error that happens when 
you're really tired and not thinking straight. So... 
...DON'T work on your car when you're over tired. 
ALWAYS work in a well ventilated area and don't inhale dust 
- it may contain asbestos or other harmful substances. 
NEVER run the engine indoors, in a confined space or over 
a pit. 
REMOVE your wrist watch, rings and all other jewellery before 
doing any work on the vehicle
 -
 and especially when working 
on the electrical system. 
DON'T remove the radiator or expansion tank filler cap when 
the cooling system is hot, or you may get scalded by escaping 
coolant or steam. Let the system cool down first and even 
then, if the engine is not completely cold, cover the cap with 
a cloth and gradually release the pressure. 
NEVER drain oil, coolant or automatic transmission fluid when 
the engine is hot. Allow time for it to cool sufficiently to avoid 
scalding you. 
ALWAYS keep antifreeze, brake and clutch fluid away from 
vehicle paintwork. Wash off any spills immediately. 
TAKE CARE to avoid touching any engine or exhaust system 
component unless it is cool enough not to burn you.  

J Job 22. Check/clean/gap spark plugs. Q Job 23. Change spark plugs. 
GENERAL. On all Tipo and Tempra petrol engines the spark 
plugs
 face forwards, allowing easy working access. 
Carefully remove the 
spark plug caps, being 
careful to pull only on 
the cap and
 not the HT 
lead. If you can't be 
sure
 to remember which 
HT lead
 belongs to 
which spark plug, 
number them from one 
end
 of the engine to the 
other. 
22B. If the electrodes of the 
plugs look rounded and worn, 
replace
 the plugs. See page 
154
 for details of 'Reading 
Your Spark Plugs. Nip' the 
cap
 tight with pliers, so that it 
can't come loose. 
Spark plugs 'tire' and lose efficiency over a period of time, 
even if they look okay. See Job 22 for information on their 
removal and replacement. Use good quality Champion or FIAT 
plugs of the correct specification. 
• Job 24. Check/dean HT leads and distributor 
cap. 
See SAFETY FIRST! at the start of this section and 
Chapter 1, Safety First! 
IMPORTANT NOTE: On latest models, there is no conven-
tional distributor and, for those cars, none of the 
following should be attempted. Illustration to Job 28C 
illustrates the type which should NOT be worked on 
except for wiping off the outer surface, with the engine 
not running. 
Remove each plug lead from the spark plugs, pulling only on 
the plug caps, not on the HT cables. Also, remove the large HT 
lead from the coil and take off the distributor cap, either by 
popping off its spring retainers if the distributor is on the side 
of the engine (front of engine bay
 -
 see illustration 25A) or by 
undoing the two retaining screws. 
24A. On later 
cars (Digiplex 
ignition -
distributor 
mounted 
horizontally on 
end of cylinder 
head) unclip and 
remove the 
22A. Unscrew the plug 
using
 the correct type of 
spark plug socket. Take 
care
 to keep the 
spanner strictly in line 
with the plug so as not to 
crack the electrode. 
22C.
 it
 is
 essential 
that the
 plug is 
gapped
 correctly. 
See Chapter 3, 
Facts
 and Figures. 
Use a
 feeler blade 
of the
 correct 
thickness, sliding it 
between
 the 
electrodes. It should 
be a firm
 sliding fit. 
Use a
 gapping tool 
or
 carefully wielded pliers to bend the curved electrode 
towards
 or away from the centre electrode. Take GREAT CARE 
not to
 damage the insulator near the tip of the plug. 
H INSIDE INFORMATION: The spark plugs screw into 
aluminium, which is easily damaged if the spark plugs do 
not
 engage their threads properly. Screw in the plugs by 
hand initially
 -
 by, say, two or three turns
 -
 before using 
the plug spanner. A light smear of copper grease on the 
plug
 threads will enable them to turn more freely and 
also
 make them easier to remove next time. Finally, 
don't over-tighten the plugs
 -
 firm hand-pressure on the 
spanner is sufficient. D 
IMPORTANT NOTE: DO NOT 
spray water dispellant or 
apply lubricant to any part 
of an electronic ignition 
distributor. (It's okay to 
clean the cap, as described, 
however.) 
shroud. Clean the 
cap and cables of 
either type with a clean rag, applying a little aerosol water-
dispellant spray to help shift oil and grime. 
24B. Check each of the HT posts (a) inside the cap for burning 
or damage, and the central carbon brush (b) to ensure that it's 
not worn down and that the 
spring loading is okay. Clean 
the dust cover (c) and rotor 
arm, and check the tip (d) for 
burning.
