My 4 cyl just goes nuts when I turn it on.. Loudest screeching, squealing sound evar. I started it for the first time tonight after 4 months of changing a bunch of stuff on it, I expected a rough start, but everytime I turn the key all hell breaks loose. I hear the engine running fine under the loud *** scream though, and it was running great last time I started it. Temperature is under the freezing point most of the time now, and I suspect the serpentine belt or water pump to be the criminals. Is there anything else that could cause such a disturbing, evil, ear shattering sound? Thanks!
note: I started it inside so the squeal might have sounded louder lol
