Garage Jargon Explained!

"Your Cambelt needs Changing" - What do they mean?

The cambelt (or timing belt) - essentially a large, strong rubber-toothed belt that connects major moving parts of your engine - needs replacing. Cam belts need replacing over time. If you don't replace your cam belt at the recommended intervals, it can cause significant damage to your engine.

WHAT SHOULD YOU BE AWARE OF?

All manufacturers recommend that you change the cambelt after either a certain number of miles or a certain number of years. Check your owner's manual to see when yours is due. This is an essential job that must be done. If you're advised that the belt needs changing before this time, ask the technician to explain why.

"Your Clutch is Slipping!" - What do they mean?

Part of the clutch mechanism which allows you to change gear smoothly is so worn it is not working properly. When you select a gear, your car will still feel like it's in neutral or, when you accelerate, the engine revs but the car doesn't go any faster.

WHAT SHOULD YOU BE AWARE OF?

Clutches are rarely repaired so you'll probably need a new one. Some technicians may suggest the gearbox also needs to be repaired or replaced at the same time. This is unlikely so always question this suggestion rather than letting the technician do it as a matter of course. If the clutch has been slipping for some time, the flywheel (a mechanical device that helps drive the engine) may also need to be replaced or skimmed (similar to the way a carpenter planes wood to produce a smooth surface). Remember, if in doubt, ask for an explanation.

"Your Head gasket has gone!" - What do they mean?

The seal between the main engine casing (known as the cylinder block) and the cylinder head (a cast iron or aluminium cover at the top of an engine) has cracked as a result of wear and tear, leading to internal engine leaks.

WHAT SHOULD YOU BE AWARE OF?

If your car is modern, the cause of the problem is unlikely to be with the head gasket. Ask your technician if he or she is sure there isn't anything else that may be responsible for the problem.

"Your Tracking is out!" - What do they mean?

Tracking refers to the front wheels being in line, as shown in the manufacturer's specifications.

WHAT SHOULD YOU BE AWARE OF?

Damaged or incorrectly adjusted tracking can affect how your car handles. This can cause it to pull to one side. It can also lead to your tyres wearing out before they should or unevenly. Your tracking can easily be affected by hitting kerbs or potholes. It is always a good idea to have your tracking checked when you have a service or when replacing the front tyres.
