Does anyone have an idea why my engine is squeaking, here is what happened. Today I replaced the serpatine belt and when I turned on the car there was no squeaking but when I turned on the ac/def I had a horrible squeaking sound. I am hoping it is just because I didn't tighten the belt enough. I am going to try to tighten it more tomorrow. I was wondering if anyone else has an idea of what it could be. Thanks
