0•10 W eekly checks There are some very simple checks which need only take a few minutes to carry out, but which could save you a lot of inconvenience and expense. These "Weekly checks" require no great skill or special tools, and the small amount of time they take to perform could prove to be very well spent, for example; M Keeping an [...]

W eekly checks 0•11 Engine oil level Before you start 4 Make sure that your car is on level ground. 4 Check the oil level before the car is driven, or at least 5 minutes after the engine has been switched off. The correct oil Modern engines place great demands on their oil. It is very important that the correct oil for your car is used (See “Lu[...]

0•12 W eekly checks Brake fluid level Warning: l Brake fluid can harm your eyes and damage painted surfaces, so use extreme caution when handling and pouring it. l Do not use fluid that has been standing open for some time, as it absorbs moisture from the air, which can cause a dangerous loss of braking effectiveness. Safety First! l If the reser[...]

W eekly checks 0•13 Screenwash additives not only keep the winscreen clean during foul weather, they also prevent the washer system freezing in cold weather - which is when you are likely to need it most. Don’t top up using plain water as the screenwash will become too diluted, and will freeze during cold weather. On no account use coolant anti[...]

0•14 W eekly checks T yr e condition and pr essur e It is very important that tyres are in good condition, and at the correct pressure - having a tyre failure at any speed is highly dangerous. Tyre wear is influenced by driving style - harsh braking and acceleration, or fast cornering, will all produce more rapid tyre wear. As a general rule, the[...]

W eekly checks 0•15 Battery Caution: Before carrying out any work on the vehicle battery, read the precautions given in "Safety first" at the start of this manual. 4 Make sure that the battery tray is in good condition, and that the clamp is tight.

9 The engine will turn over more easily if the spark plugs are removed. Do not rotate the engine by turning the camshaft sprocket as this will stretch the timing belt. Use the alternator drivebelt (V-belt) or jack up one front wheel and with the engine in gear rotate the roadwheel. Do not turn the engine with any of the shims removed, otherwise the[...]

14 Antifreeze concentration check 2 Warning: Wait until the engine is cold before checking antifreeze. Do not allow antifreeze to come in contact with your skin or painted surfaces of the vehicle. Rinse off spills immediately with plenty of water. Never leave antifreeze lying around in an open container or in a puddle in the driveway or on the gara[...]

13 Wipe clean the distributor cap and make sure that the carbon brush moves freely against the tension of the spring. Clean the metal segments in the distributor cap but do not scrape away any metal, otherwise the HT spark at the spark plugs will be reduced. Also clean the HT leads and coil tower. 14 Refit the distributor cap and interference scree[...]

15 Connect a tachometer in accordance with the manufacturer’s instructions. 16 Start the engine and run it at idling speed. 17 Point the timing light at the timing mark and pointer which should appear to be stationary and aligned.

Air conditioning system The air conditioning unit works on exactly the same principle as a domestic refrigerator, having a compressor, a condenser and an evaporator. The condenser is attached to the vehicle radiator system. The compressor, belt- driven from the crankshaft pulley, is installed on a bracket on the engine. The evaporator is installed [...]

Air conditioning refrigerant Although the refrigerant is not itself toxic, in the presence of a naked flame (or a lighted cigarette) it forms a highly toxic gas.
