Battery
Caution: Before carrying out any work on the vehicle battery, read the precautions given In "Safety first" at the start of this manual. • Make sure thai the battery tray is in good condition, and that the clamp Is tight. Coirosion on the tray, retaining clomp and the battery itself can be removed with a solution of water and baking soda, Thoroughly rinse all cleaned areas with water. Any metal parts damaged by corrosion should be covered with a zinc-based primer, then painted. • Periodically (approximately every three months), check the charge condition of the battery as described In Chapter SA. • If the battery Is flat, and you need to jump start your vehicle, see Roadside Repalrz.
Battery corrosion can be kept to a minimum by applying o layer of petroleum Jelly to the clamps and terminals after they are reconnected

6 Underbody sealant check
I
1 Jack up the front and rear of the car and support It securely on axle stands (see Jacking and vehicle support). Alternatively position the car over an inspection pit. 2 Check the underbody. wheel housings and side sills for rust and/or damage to the under-body sealant. If evident, repair as necessary.
7 Hose and fluid leak check ^
I
1 Visually Inspect the engine joint laces, gaskets and seals for any signs of water or oil leaks. Pay particular attention to the areas around the camshaft cover, cylinder head, oil (liter and sump joint faces. Bear in mind that.
A leak In the cooling system will usually show up as white or rust~coloured deposits on the area adjoining the leak
over a period of time, some very slight seepage from these areas is to be expected -what you are really looking for is any indication of a serious leak (see Haynes Hint). Should a leak be found, renew the offending gasket or oil seal by refemng to the appropriate Chapters in this manual. 2 Also check the security and condition of all the engine-related pipes and hoses. Ensure that all cable-ties or securing clips ore In place and In good condition, Clips which are broken or missing can lead to chafing of the hoses, pipes or wiring, which could cause more serious probioms In the luture. 3 Carefully check the radiator hoses and heater hoses along their entire length. Renew any hose which is cracked, swollen or deteriorated, Cracks will show up better if the hose is squeezed. Pay close attention to the hose clips that secure the hoses to the cooling system components. Hose clips can pinch and puncture hoses, resulting in cooling system leaks. 4 Inspect all 'he cooling system components {hoses. |olnt faces etc.) for leaks. A leak in the coolmg system will usually show up as white-or rust-coloured deposits on the area adjoining the leak. Where any problems of this nature are found on system components, renew the component or gaskel with reference to Chapter 3. 5 Where applicable, inspect the automatic transmission fluid cooler hoses for leaks or deterioration. 6 With the vehicle raised, inspect the fuel tank and filler neck for punctures, cracks and other damage. The connection between the filler neck and tank Is especially critical. Sometimes a rubber filler neck or connecting hose will leak due to loose retaining clamps or deten orated rubber. 7 Carefully check all rubber hoses and metal fuel lines leading away Irom the fuel tank. Check for loose connections, deteriorated hoses, crimped lines, and other damage. Pay particular attention to the vent pipes and hoses, which often loop up around the fitter neck and can become blocked or crimped. Follow the lines to the front of the vehicle, carefully inspecting them all the way. Renew damaged sections as necessary. 8 From within tne engine compartment,
check the security of all fuel hose attachments and pipe unions, and inspect the fuel hoses and vacuum hoses for kinks, chafing and deterioration. 9 Where applicable, check the condition of the power steering fluid hoses and pipes.
8 Exhaust system check fe
1 With the engine cold (at least an hour after the vehicle has been driven), check the complete exhaust system from the engine to the end of the tailpipe. The exhaust system is most easily checked with the vehicle raised on a hoist, or suitably supported on axle stands (see Jacking and vehicle support), so that the exhaust components are readily visible and accessible. 2 Check the exhaust pipes and connections for evidence of leaks, severe corrosion and damage. Make sure thai all brackets and mountings are in good condition, and that all relevant nuts and bolts are tight, Leakage at any of the Joints or in other parts of the system will usually show up as a black sooty stain in the vicinity of the leak. 3 Rattles and other noises can often bo traced to the exhaust system, especially the brackets and mountings. Try to move the pipes and silencers. If the components are able to come Into contact with the body or suspension parts, secure the system with new mountings Otherwise separate the joints {if possible) and twist the pipes as necessary to provide additional clearance.
9 Driveshaft gaiter check
9.1 Checking the condition of a driveshaft gaiter
1
1 With the vehicle raised and securely supported on stands (see Jacking and vehicle support), turn the steering onto full lock, then s'owly rotate the roadwheel. Inspect the condition of Ihe outer constant velocity (CV) joint rubber garters, squeezing the gaiters to open out the folds. Check for signs of cracking, splits or deterioration of the rubber, which may allow the grease to escape, and lead to water and grit entry into the joint. Also check the security and condition of the retaining clips. Repeat these checks on the Inner CV joints (see Illustration), If any damage or deterioration Is found, the gaiters should be renewed (see Chapter 8, Section 3). 2 At the same time, check the general condition of (he CV joints themselves by first holding (he driveshaft and attempting to rotate the wheel. Repeat this check by holding the inner joint and attempting to rotate the driveshaft. Any appreciable movement indicates wear in the joints. wear In the driveshaft splines, or a loose driveshaft retaining nut

5.1 Depress tho button on the top of the brake fluid reservoir cap
around the camshaft cover, cylinder head, oil filter and sump joint faces. Bear in mind that, over a period of time, some very slight seepage from these areas is to be expected -what you are really looking for is any indication of a serious leak (see Haynes Hint). Should a teak be found, renew the offending gasket or oil seal by referring to the appropriate Chapters In this manual, 2 Also check the security and condition of all the engine-related pipes and hoses. Ensure thai all cable-ties or securing clips are In place and in good condition. Clips which are broken or missing can lead to chafing of the hoses, pipes or wiring, which could cause more serious problems In the future. 3 Carefully check the radiator hoses and heater hoses along their entire length. Renew any hose which is cracked, swollen or deteriorated. Cracks will show up better If the hose is squeezed. Pay close attention to the hose clips that secure the hoses to the cooling system components. Hose clips can pinch and puncture hoses, resulting in leaks. 4 Inspect all the cooling system components (hoses. )olnt faces etc.) for leaks. A leak in the cooling system will usually show up as white or rust-coloured deposits on the area adjoining the leak, Where any problems of this nature are found on system components, renew the component or gasket with reference to Chapter 3. 5 With the vehicle raised, inspect the fuel tank and filler neck for punctures, cracks and other damage, The connection between the filler neck and tank is especially critical. Sometimes a rubber filler neck or connecting hose will leak due to loose retaining clamps or deteriorated rubber. 6 Carefully check all rubber hoses and metal fuel lines leading away from the fuel tank. Check for loose connections, deteriorated hoses, crimped lines, and other damage. Pay particular attention to the vent pipes and hoses, which often loop up around the filler neck and can become blocked or crimped. Follow the lines to the front of the vehicle, carefully Inspecting them all the way. Renew damaged sections as necessary.
6.2 Check the thickness of the pad friction material through the hote on the front of the caliper
7 With the vehicle raised, check along the length of the underside for leaks from the metal brake lines, caused by damage or corrosion. 8 At each front brake caliper, check the area around the brake pipe unions and the bleed nipples for hydraulic fluid leakage, 9 Remove the front roadwheels and chock for fluid leakage from the area around the caliper piston seal. Check that the tip of the piston dust seal is correctly located in its groove. If it has been displaced, the brake caliper should be removed and overhauled as described in Chapter 9, to check for internal dirt Ingress or corrosion. 10 Check the area surrounding the master cylinder and vacuum servo unit for signs of corrosion, Insecurity or hydraulic fluid leakage. Examine the vacuum hose leading to the servo unit for signs of damage or chafing. 11 From within the engine compartment, check the security of all fuel hose attachments and pipe unions, and Inspect the fuel hoses and vacuum hoses for kinks, chafing and deterioration. 12 Where applicable, check the condition of the power steering fluid hoses and pipes.
A leak in the cooling system will usually show up as white or rust coloured deposits on the area adjoining the leak.

5.11 Special Fiat tool necessary to accurately position the camshaft before fitting the sprocket
Camshaft sprocket Removal 11 Remove the timing belt as descnbed in Section 4. A special Rat tool (see illustration) is necessary to position the camshaft before refitting the sprocket, however il the original camshafl Is being re-used, use of the special tool can be ovoided by accurately marking the camshaft position before removing the sprocket. Caution: On later 1996 models the camshaft sprocket can be moved In either direction on tho camshaft location dowel. 12 The camshaft sprocket must now oe held stationary whilst the retaining bolt is loosened. This is no problem on later models where the sprocket incorporates holes, however some early models have a sprocket without holes • on this type Fiat technicians use a special tool
V*— r^r
To make a camshaft sprocket holding tool, obtain two lengths of steel strip about 6 mm thick by 30 mm wide or simllar, one 600 mm long, the other 200 mm long (all dimensions approximate). Bolt the two strips together to form a forked end, leaving tho bolt slack so that the shorter strip can pivot freely. At the end of each 'prong' of the fork, secure a bolt with a nut and a locknut, to act as the futcrums; theso will engage with the cut'Outs In the sprocket, and should protrude by about 30 mm
which clamps on the sprockot teeth. If this tool is not available, it may be possible to make up a similar tool. On later models a sprocket holding tool can easily be made (see Toot Tip). 13 On 1996-on models mark the position of the camshaft in relation to the cylinder head.

9 Air conditioning system -general Information and precautions
General information An air conditioning system is available on certain models. It enables the temperature of Incoming air to be lowered, and also dehumidifies the air, which allows rapid demisting and increased comfort. The cooling side of the system works In the same way as a domestic refrigerator. Refrigerant gas is drawn into a belt-driven compressor where the increase In pressure causes the refrigerant gas to turn to liquid. It then passes through a condenser mounted on the front of the radiator, where it is cooled. Tho liquid then passes through an expansion vaive to an evaporator, where it changes from liquid under high pressure to gas under low pressure. This change is accompanied by a drop in temperature, which cools the evaporator and hence the air passing over it. The refrigerant returns to the compressor, and the cycle begins again. The air bfown through the evaporator passes to the air distribution unit where it is mixed, if required, with hot air blown through the heater matrix to achieve the desired temperature in the passenger compartment. The heating side of ihe system works in the same way as on models without air conditioning (see Section 8). The system Is electronically-controlled. Any problems with the system should be referred to a Fiat dealer.
Precautions With an air conditioning system. It is necessary to observe special precautions whenever dealing with any part of the system, or its associated components. If for any reason the system must be disconnected, it Is

Warning: Hydraulic fluid Is poisonous; thoroughly wash off spllfs from bare skin without delay. Seek Immediate medical advice If any fluid is swallowed or gets into the eyes. Certain types of hydraulic fluid are Inflammable and may ignite when brought into contact with hot components; when servicing any hydraulic system, It is safest to assume that the fluid IS Inflammable, and to take precautions against the risk of fire as though ft were petrof that was being handled. Hydraulic fluid Is an effective paint stripper and will also attack many plastics. If spillage occurs onto painted bodywork or fittings, ft should be washed off Immediately, using copious quantities of fresh water. It Is also hygroscopic - It can absorb moisture from the air, which then renders it useless. Old fluid may have
suffered contamination, and should never be re-used. When topping-up or renewing tho fluid, always use tha recommended grade, and ensure that It comes from a new seated container. General information 1 Whenever the clutch hydraulic lines are disconnected for service or repair, a certain amount of air will enter the system. The presence of air In any hydraulic system will Introduce a degree of elasticity, and in the clutch system this will translate into poor pedal feel and reduced travel, leading to inefficient gear changes and even clutch system failure. For this reason, the hydraulic lines must be sealed using hose clamps before any work la carried out and then on completion, topped up and bled to remove any air bubbles. 2 To seal off Ihe hydraulic supply to tha clutch slave cylinder, fit a proprietary brake hose clamp to the flexible section of the hose located over the transmission and tighten it securely. It will be necessary to remove the battery and battery tray to access the hose. 3 The most effective way of bleeding the clutch hydraulic system is to use a pressure brake bleeding kit. These are readily available in motor accessories shops and are extremely effective: the following sub-section describes bleeding the clutch system using such a kit. The alternative method is to bleed the system by depressing tho clutch pedal • refer to Chapter 9. Section 11, for details of this method.
Bleeding 4 Remove the protective cap from Ihe bleed nipple on the slave cylinder. Access can be improved by removing the battery and tray with reference to Chapter 5A. 5 Fit a ring spanner over the bleed nipple head, but do not slacken it at this point. Connect a length of dear plastic hose over the nipple and insert the other end into a clean container. Pour hydraulic fluid into the container, such that the end of the hose is covered. 6 Following the manufacturer's instructions, pour hydraulic fluid into the bleeding kit vessel 7 Unscrew the vehicle's fluid reservoir cap, then connect Ihe bleeding kit fluid supply hose to the reservoir. 8 Connect the pressure hose to a supply of compressed air - a spare tyre is a convenient source. Caution: Check that the pressure In the tyre does not exceed the maximum supply pressure quoted by the kit manufacturer, let soma sir escape to reduce the pressure, if necessary. Gently open the air valve and allow the air and fluid pressures to equalise. Check that there ere no teaks before proceeding. 9 Using the spanner, slacken the bleed pipe nipple until fluid and air bubbles can be seen to flow through the tube, into the container.
Maintain a steady flow until the emerging fluid la free of air bubbles; keep a watchful eye on the level of fluid in the bleeding kit vessel and the vehicle's fluid reservoir • if it Is allowed to drop too low, air may be forced into the system, defeating the object of the exercise. To refill the vessel, turn off the compressed air supply, remove the lid and pour In en appropriate quantity of clean fluid from a new container - do not re-use the fluid collected in the receiving container. Repeat as necessary until the ejected fluid is bubble-free. 10 On completion, pump the olutch pedal several times to assess its feel and travel.
