Look for cracks, splitting and fraying on the surface of the belt: check also for signs of glazing (shiny patches) and separation of the belt plies. If damage or wear Is visible, the relevant belt should be renewed. 7 If the condition of the belt Is satisfactory, check Ihe drivebeit tension as described below.

Adjust the tension correctly as described below.
15.7 Checking a valve clearance with a feeler blade
Tensioning 21 Correct tensioning of the belt will ensure that it has a long life. A belt which Is too slack will slip and perhaps squeal. Beware, however, of overtightening, as this can cause wear in the alternator, power steering pump or air conditioning compressor bearings. Note: Fiat recommend use of their special tensioning tool however the fallowing procedure will set the tension correctly. 22 The belt(s) should be tensioned so that, under firm thumb pressure, there is approximately 5.0 mm of free movement at the mid-point between the pulleys. To adjust the alternator drivebeit, slightly tighten the adjustment bolt then swivel the alternator outwards until tne beft tension Is correct. Fully tighten the adjustment bolt followed by the pivot bolt then refit the rpm sensor. 23 On models with power steering and/or air conditioning, fit the relevant drivebeit over the pulleys then turn the adjusting bolt until the tension is correct. Secure the adjusting bolt by tightening Ihe locknut, then tighten the remaining mounting bolts. Refit any remaining dnvebelts and all the components removed. 24 Refit the inner cover and wheel, lower the vehicle to the ground, then reconnect the battery negative terminal,

engines which utilise self-adjusting hydraulic tappets. 1 The importance of having the valve clearances correctly adjusted cannot be overstressed, as they vitally affect the performance of the engine. Adjustment should only be necessary when the valve gear has become noisy, after engine overhaul, or when trying to trace the cause of power loss. The clearances are checked as follows. The engine must be cold for the check to be accurate. 2 Apply the handbrake then jack up the right* hand front of the vehicle and support on an axle stand (see Jacking and vehicle support). Engage 4th gear. The engine can now be rotated by turning the right-hand front road wheel. 3 Remove all spark plugs as described In Section 19. 4 Remove the camshaft cover as described In Chapter 2A. 5 Each valve clearance must be checked when the high point of the cam lobe is pointing directly upward away from the cam follower. 6 Check the clearances In the firing order 1-3-4-2.

cylinder being at the timing bell end of the engine. This will minimise the amount of crankshaft rotation required. 7 Insert the appropriate feeler blade between the heel of the cam and the cam follower shim of the first valve (see illustration). II necessary alter the thickness of the feeler blade until it is a stiff, sliding fit. Record the thickness, which will, of course, represent the valve clearance for this particular valve. 8 Tum the engine, check the second valve clearance and record it. 9 Repeat the operations on all the remaining valves, recording their respective clearances. 10 Remember that the clearance for Inlet and exhaust valves differs • see Specifications. Counting from the timing cover end of the engine, the valve sequence is: tnlet 2-4-5-7 Exhaust 7-3-6-$ 11 Where clearances are incorrect, the particular shim will have to be changed. To remove the shim, turn the crankshaft until the high point of the cam Is pointing directly upward. The cam follower will now have to be depressed so that the shim can be extracted. Special tools are available from your Fiat dealer to do the job, otherwise you will have to make up a forked (ever to locate on the rim of the cam follower. This must allow room for the shim to be prised out by means of the cut-outs provided in the cam follower rim {see illustration). 12 Once the shim is extracted, establish its thickness and change It for a thicker or thinner one to bring the previously recorded

19 Spark plug renewal
1 The correct functioning of the spark plugs is vital for the correct running and efficiency of the engine. It is essential that the plugs fitted are appropnate for the engine (a suitable type is specified at the beginning of this Chapter. If this type is used and the engine Is In good condition, the spark plugs should not need attention between scheduled replacement intervals Spark plug cleaning Is rarely necessary, and should not be attempted

19.4 Removing the spark plugs
unless specialised equipment Is available, as damage can easily be caused to the firing ends. 2 To remove the plugs first remove the air cleaner assembly (8-vaive engines) or the a»r cleaner, resonator and inlet air duct (16-valve engines) with reference to Chapter 4A or 4B. if the marks on the original-equipment spark plug (HT) leads cannot be seen, mark the leads 1 to 4, to correspond to the cylinder the lead serves (No 1 cylinder is at the timing belt end of the engine). Pull the leads from the plugs by gripping the end fitting, not the lead, otherwise the lead conneciion may be Iractured (see illustrations) 3 It is advisable to remove the dirt from the spark plug recesses using a clean brush, vacuum cleaner or compressed air before removing the plugs, to prevent dirt dropping into the cylinders. 4 Unscrew the plugs using a spark plug spanner, suitable box spanner or a deep socket and extension bar (see illustration). Keep the socket aligned with the spark plug • If it is forcibly moved to one side, the ceramic insulator may be broken off. As each plug is removed examine 4 as fallows. 5 Examination of the spark plugs will give a good Indication of the condition of the engine. If the Insulator nose of the spark plug Is clean and white, with no deposits, this is Indicative of a weak mixture or too hot a plug (a hot plug transfers heal away from the electrode slowly, a cold plug transfers heat away quickly). 6 If the tip and insulator nose are covered with hard black-looking deposits, this
19.2b ... and on 16-valve engines
19.9 Ad|ustlng a spark plug electrode gap
indicates that the mixture Is too rich. If the plug is black and oily, then It is likely that the engine is fairly worn, as well as the mixture being too rich. 7 If the Insulator nose is covered with light tan to greyish-brown deposits, then the mixture Is correct and it is likely that (he engine Is in good condition. 6 The spark plug electrode gap is of considerable importance as, if it Is too large or too small, the size of the spark and its efficiency will be seriously impaired. The gap should be set to the value given in the Specifications at the beginning of this Chapter. 9 To set the gap. measure it with a feeler blade and then bend open, or closed, the outer plug elect/ode until the correct gap l9 achieved. The centre electrode should never be bent, as this may crack the insulator and cause plug I allure, if nothing worse. If using feeler blades, the gap is correct when the appropriate-size blade is a firm sliding fit (see illustration). 10 Special spark plug electrode gap adjusting tools are available from most motor accessory shops, or from some spark plug manufacturers, 11 Before fitting the spark plugs, check that the threaded connector sleeves are tight, and that the plug exterior surfaces and threads are clean (see Haynes Hint). 12 Remove the rubber hose (If used), and tighten the plug to the specified torque using the spark plug socket and a torque wrench, Refit the remaining spark plugs In the same manner. 13 Connect the HT leads In their correct order, and refit any components removed for access.
It is very often difficult to insert spark plugs into their holes without cross-threading them. To, avoid this possibility, fit a short length of Si 16 Inch Internal diameter rubber hose over the end of the spark plug. The flexible hose acts as a universal Joint to help align the plug with the plug hole. Should the plug beginto cross-thread, the hose will slip on the spark plug, preventing thread damage to the cylinder head

leakage. 5 For a comprehensive check, the brake drum should be removed and cleaned. This
will allow the wheel cylinders to be checked, and the condition of the brake drum itself to be fully examined (see Chapter 9). 6 Refit the lubber plugs then lower the car to the ground.
30 Timing belt renewal
Refer to Chapter 2A or 2B. Note: Although the norma/ interval for timing belt renewal is 70 000 miles (105 000 km), it is strongly recommended that the interval Is reduced on vehicles which are subjected to intensive use. ie, mainly short journeys or a lot of stop-start driving. The actual belt renewal interval is therefore very much up to the individuaf owner. That being said, it is highly recommended to err on the side of safety, and

Children and pets are attracted by its sweet smell, but ant/freeze can be fatal if ingested. 1 With the engine completely cold, cover the expansion tank cap with a wad of rag. and slowly turn the cap anticlockwise to relieve the pressure in the cooling system (a hissing sound will normally be heard). Wait until any pressure remaining in the system is released, then continue to tum the cap until it can be removed. 2 Position a suitable container beneath the radiator bottom hose connection, then release the retaining clip and ease the hose from the radiator stub (see illustration).

Indicated In
the Specifications. 24 8efore adding antifreeze, the cooling system should be completely drained, preferably flushed, and all hoses checked for condition and security. 25 After filling with antifreeze, a label should
be attached
to the expansion tank, stating the type and concentration of antifreeze used, and the date installed. Any subsequent lopping-up should be made with the same
type and
concentration of antifreeze. 26 Do not use engine antifreeze In the windscreen/tailgate washer system, as it will
cause damage to the vehicle paintwork. A screenwash additive should be added to the washer system in the quantities stated on the bottle.
34 Brake fluid renewal | I

A


Warning: Brake hydraulic fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring H. Do not use fluid that has been standing open for some t/me, as it absorbs moisture from the air. excess moisture can cause a dangerous ioss of braking effectiveness. 1 The procedure is similar to that for the bleeding of the hydraulic system as described in Chapter 9, except that the brake fluid reservoir should be emptied by siphoning, using a clean poultry baster or similar before starting, and allowance should be made for the old fluid to be expelled when bleeding a section of the circuit. 2 Working as described In Chapter 9, open the first bleed screw in the sequence, and
pump the brake pedal gently until nearly all the old fluid has bsen emptied from the master cylinder reservoir.
Old hydraulic fluid Is Invariably much darker In colour than the new, making It easy to distinguish the two.
3 Top-up to the MAX level with new fluid, and continue pumping until onty the new fluid remans in the reservoir, and new fluid can be seen emerging from the bleed screw. Tighten the screw, and top the reservoir level up to the MAX level line. 4 Work through all the remaining bleed screws in the sequence until new fluid can be seen at all of them. Be careful to keep the master cylinder reservoir topped-up to above the MIN level et all times, or air may enter the system and greatly increase the length of the task. 5 When the operation Is complete, check that all bleed screws are securely tightened, and that their dust caps are refitted. Wash off all traces of spilt fluid, and recheck the master cylinder reservoir fluid level. 6 Check the operation of the brakes before taking the car on the road.

Valve clearance check and
adjustment
1 The Importance of having the valve clearances correctly adjusted cannot be Distressed, as they vitally affect the performance of the engine. Adjustment should only be necessary when the valve gear nas become noisy, after engine overhaul, or when trying to trace the cause of power loss. The clearances are checked as follows. The engine must be cold for the check to be ttcurate. 2 Apply the handbrake then jack up the right-hand front of the vehicle and support on an axle stand (see Jacking and vehicle support). Engage 4th gear. The engine can now be rotated by turning the right-hand front roadwfteei. 3 Remove ail four glove plugs as described In Chapter 5C. 4 Remove the air cleaner cover and air duct
then
remove the camshaft cover as described
in
Chapter 2C. 6 Each valve clearance must be checked wnen the high point of the cam is pointing directly upward away from the cam follower. 6 Check the clearances in the firing order 1-3-4-2, No 1 cylinder being at the timing belt end of the engine. This will minimise the amount of crankshaft rotation required. 7 Insert the appropriate feeler blade between
the heel
of the cam and the cam follower shim of the First valve (see Illustration). If necessary alter the thickness of the feeler blade until it is a stiff, sliding fit. Record the thickness, which will, of course, represent the
vafve
clearance tor Ihis particular valve. 8 Turn the engine, check the second valve devance and record it. t Repeat the operations on all the remaining valves. recording their respective clearances. 10 Remember that the clearance for inlet and exhaust valves differs - see Specifications. Counting from the timing cover end of the
engine,
the valve sequence is: Wef 2-4-5-7 Etfiat/sf 7-3-6-8
11 Where clearances are incorrect the particular shim will have to be changed. To remove the shim, turn the crankshaft until the high point of the cam is pointing directly upward. The cam follower will now have to bo depressed so that the shim can be extracted. Special tools are available from your Fiat dealer to do the job. otherwise you will have to make up a forked lever to locate on the rim of ihe cam follower. This must allow room for the shim to be prised out by means of the cut-outs provided in the cam follower rim (see illustration). 12 Once Ihe shim is extracted, establish Its thickness and change it for a thicker or thinner one to bring the previously recorded clear-ance within specification, For example, if the measured valve clearance was 1.27 mm too great, a shim thicker by this amount will be required. Conversely, if the clearance was 1.27 mm too small, a shim thinner by this amount will be required. 13 Shims have their thickness (mm) engraved on ihem; although the engraved side should be fitted so as not to be visible, wear still occurs and often obliterates the number. In this case, measuring their thickness with a metric micrometer is the only method to establish their thickness (see illustration). 14 In practice, if several shims have to be changed, they can often be interchanged, so avoiding the necessity of having to buy more new shims than is necessary. 15 If more than two or three valve clearances are found to be incorrect, it will be more convenient to remove the camshaft lor easier removal of the shims. 16 Where no clearance can be measured, even with the Ihinnest available shim in position, the valve will have to be removed and the end of its stem ground off squarely. This will reduce its overall length by the minimum amount to provide a clearance. This job should be entrusted to your dealer as it is important to keep the end of the valve stem square. 17 On completion, refit the camshaft cover and gasket, air cleaner and duct, and glosvplugs. 18 Lower the vehicle to the ground.
19 Hinge and lock lubrication
I
1 Lubricate the hinges of the bonnet, doors and tailgate with a light general-purpose oil. Similarly, lubricate all latches, locks and lock stnkers. At the same time, check the security and operation of all the locks, adjusting them if necessary (see Chapter 11). 2 Lightly lubricate the bonnet release mechanism and cable with a suitable grease.
20 Headlight beam adjustment
I
1 Accurate adjustment of the headlight beam Is only possible using optical beam-setting equipment, and this work should therefore be carried out by a Fiat dealer or service station with the necessary facilities. In an emergency, however, the following procedure will provide an acceptable light pattern. 2 Position the car on a level surface with tyres correctly inflated, approximately 10 metres in front of, and at right-angles to, a wall or garage door. 3 Draw a horizontal tine on the wall or door at headlamp centre height. Draw a vertical line corresponding to the centre line of the car. then measure off a point either side of this, on the horizontal line, corresponding with the headlamp centres. 4 Switch on the main beam and check that the areas of maximum Illumination coincide with the headlamp centre marks on the wall. If not, turn the adjustment screw located on the upper Inside edge of the headlight unit to adjust the beam laterally, and the adjustment screw located on the upper outside edge of the headlight unit to adjust the beam vertically. On models with electric headlight adjustment, make sure that it Is set at its basic setting before making the adjustment,
