1 Open the bonnet and inspect the engine joint faces, gaskets and seals for any signs of coolant or oil leaks. Pay particular attention to the areas around the rocker 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 but what you are really looking for is any indication of a serious leak. Should a leak be found, renew the offending gasket or oil seal.

2 Carefully check the condition and security of all under bonnet coolant, fuel, power steering and brake pipes and hoses. 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 system components. Hose clips can pinch and puncture hoses, resulting in leaks. If wire type hose clips are used, it may be a good idea to replace them with screw-type clips (see Haynes Hint).

3 Check the condition of all exposed wiring harnesses. Ensure that all cable-ties are in place and in good condition. Ties which are broken or missing can lead to chafing of the wiring which could cause serious problems in the future.

4 Wipe away any dirt which has accumulated on the outside of the alternator and check that its cable connector is pushed firmly onto its terminals.

5 Clean the ignition system HT and LT leads by wiping along their length with a fuelmoistened cloth. Inspect each lead for damage and renew if defective in any way.

Ensure that all lead connections are secure and where applicable, protected (see illustration).

6 Check that all HT and LT leads are correctly routed and clear of moving or hot engine components.

7 Any corroded HT or LT lead connection must be cleaned. A smear of petroleum jelly (not grease) applied to the cleaned connection will help to prevent further corrosion.

8 Check the transmission for obvious oil leaks and investigate and rectify any problems found.

9 Where accessible, inspect the fuel filler neck for punctures, cracks and other damage.

Sometimes a rubber filler neck or connecting hose will leak due to loose retaining clamps or deteriorated rubber.
