when does a serpentine belt need to be replaced
Answer by lynn (821). I'm not sure on this I think it probably depends on how much wear and tear is put on the car. I have a 15 year old car and to my knowledge replaced the serpentine belt once because it broke when i had to have the water pump replaced.I drove it a long time before this happened.add a comment.'m not sure on this I think it probably depends on how much wear and tear is put on the car.
