I’m an MOT mechanic who’s fixed thousands of cars – you can save HUNDREDS by checking key vehicle part

AN MOT mechanic has revealed how you can save hundreds by checking a key vehicle part.

Craig, who works at Walsall Wood Tyre & Service in Walsall, West Midlands, took to TikTok to share the money-saving tip with his followers.

Craig urged drivers to be sure to bear the condition of their cam belt in mind, especially when buying a new car.

He said: "The cam belt is usually encased in a plastic, dust-free area of the engine.

"You may see some small cracks form in the belt, which will be an indication it's time to change it.

"If you have got no [car] history, assume it has never been changed and that it is absolutely desperate."

The cam belt regulates the timing of the camshaft and keeps it in step with the crankshaft.

As a system, these three components use the rotational motion of the engine to open and close the intake and exhaust valves at the correct times.

If these functions are mistimed, it could affect your engine's performance or even damage it.

Replacing the belt usually costs between £300 and £650, but doing so can prevent thousands of pounds worth of engine damage.

For example, if you are forced to replace your cylinder head due to poor cam timing, it will cost you around £1400 on top of a new cam belt too.

Craig added: "You can never change a cam belt too early.

"If you change it too early, you still have an engine.

"If you change it too late, your big end ends up in a bucket."
