Timing Belt Usually, technicians recommend replacing it with a fan belt or something else installed in front of the engine. Timing belts usually have a service life of 100,000 – 150,000 km or 60,000 – 90,000 miles. You should check the replacement time from your car’s manual.
Some European cars are required to change every 200,000 km or 120,000 miles.
You have to think at the same time whether what else should replace other than the timing belt.
Most technicians will recommend that you replace the belt pulley, tensioner, and water pump. Why? It’s because these parts will work with the belt and they can wear out.
But, as we said before, the carmaker may require that changes are necessary. You shall consider these things before making a decision.
However, we recommend that you change them together as it may reduce the labor cost for replacing multiple times.
