After how many miles of driving should the timing belt on a car be changed?

Answer 1

Depending of the car 70k to 100k miles. There is no sensor to prevent engine damage if the belt breaks. If you have an interference engine I would definitely replace it at the manufacturers recommended service interval.

Answer 2

WRONG! Many OHC cars will suffer major damage if the belt breaks. It depends on the car. The engine is spinning at thousands of revolutions per minute when that belt breaks - if it's an interference design, the valves at least will be toast.

Use your manufacturers mileage recommendation on when to change it. Usually its between 60k and 100k.

Note that not all cars have belts, in fact most have chains. Never need replacing during any reasonable life span for an engine.

Answer 3

After 100,000 miles is a good time. Or every 4 years. Which ever comes first.

Answer 4

what ever your manual recommends the manufacturer spends plenty on research on that stuff if it breaks it will cost you ten times for the repair than it would to replace the belt

bent valves and piston damage can occur if a belt snaps

Answer 5

It really varies from car to car. Usually between 75,000-100,000 on average.

I usually just wait until one breaks, and then replace it. All overhead cam cars have sensors that shut down the engine when they sense a broken belt (or if it jumps time) to keep it from causing any damage to the engine.

Answer 6

For most vehicles around 90,000 mi.
