Serpentine belt problem? Weird noise when starting car, until warm...
Off and on I have a screeching/whining noise coming from the engine bay when I start my car. It only does it if its been sitting in the driveway while its been raining a lot or I just washed it. I think its the serpentine belt, since it stops the noise when it warms up and it gets louder and more apparent when I accelerate or rev the engine. It has 102,000+ miles on it, so either way Ill probably replace it, but it doesnt have really any signs of cracking or bad wear. Any ideas of what the cause is? Dad guessed either the belt or water pump, but we havent really been able to diagnose it yet, waiting for the weather to clear up.
my car does the exact same thing. my water pump has seen better days, i know for a fact. it's got a very slow leak, and it wasn't doing it until the water pump decided to be a *****. i need to buy a new water pump and a goodyear gatorback belt. i'm sure that'll fix my problem. it'll probably fix yours too.
