I have a 2001 Gt vert. when i got the car after it got hot the car would hiss at idle or when im at a crawl. i checked it out and found that one of the pulleys was bad. I replaced it along with the belt. but i got a louder and higher pitched noise. I checked the alternator and it would squeel when i turned it by hand so i replaced it with my friends out of a 2003 gt but i still got the same problem! the noise seems to only come from the front part of the engine and it runs from idle to about 3k rpm...help me out guys!!!!!!
