What happens if your timing belt breaks while you are driving?

What happens if your timing belt breaks while you are driving?

If a timing belt breaks, the engine will no longer work. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This will cause the pistons to strike the valves that left open.

What does it sound like when timing belt breaks?

When the timing belt breaks your car will be very quiet – there will be deadly silence coming from the engine compartment. Nothing, it won’t be able to run. If it snaps, and it is an interference motor, you will hear a bang or clunk as the pistons hit the valves, and then it will die.

What happens when a timing chain or belt breaks?

But these two components will collide if the timing belt breaks. This causes there to be damage to the camshaft, cylinder, piston, valve, and cylinder head. These engine components are quite expensive to replace.

How much does a broken timing belt cost?

Damage can range from a few bent valves (requires a new or rebuilt cylinder head) to complete destruction of the engine (pistons, cylinders, cylinder heads and more). Repairs costs can range between several hundred to several thousand dollars.

Why do I need a toothed timing belt?

In an interference engine the timing belt or chain is also critical to preventing the piston from striking the valves. A timing belt is usually a toothed belt—a drive belt with teeth on the inside surface. To work properly, a timing belt needs to be under certain tension that is controlled by a timing belt tensioner.

How often should a timing belt be inspected?

It is recommended that you have your timing belt or timing chain inspected at least once per year. When you have a mechanic or auto technician perform an oil change or tune-up, you should have them inspect your belt or chain to see its condition. They’ll be able to tell if it is about to break or not.
