Q: Is it safe to change pulleys?

asked by on

Will changing my tensioner pulley to a lightweight pulley be safe for my car?

My car has 76000 miles.
My car has an automatic transmission.

As long as the pulley was designed to replace your pulley then you should not have any problems. The tensioner is designed to put a specified amount of pressure on the belt and should not be modified to reduce the pressure in any way or the belt may come off. The pulley changing to a lightweight style pulley is safe to do as long as it is certified to work with the vehicle it is installed on.
