When you accelerate does your car make a squeaking sound? If so, then most likely your belt tensioner has gone bad and the belt is now slipping making that sound or the bearing on the tension pulley has gone bad. You will see the part is all greasy due to the leaked oil in the shock and it will be covered in dirt that has stuck to the oil.

In this video, I’ll show you how to spot the bad belt tensioner, remove and install a new one.

While you have this area open, check out the water pump and see if it is showing any signs of leaking. See this video to see the early signs of water pump leaking and how to replace it.
