JeremyH Well, I have taken our 2005 Corolla into the stealership twice now for a faulty belt tensioner and twice they swear that there is nothing wrong with it. This time, it is leaking around the rubber boot. The belt squeals when the engine is cold and when you tighten the tensioner by hand, the noise subsides. The dealer replaced the belt...which was perfectly fine.This is getting quite old.Does anyone know the torque that the tensioner should provide when functioning properly? Maybe I can prove to them that it is faulty by providing the proper torque specs and showing that it is not meeting that specification.How many of you also have this problem?
