Occasionally I hear a hissing sound coming from the front of the car. I haven't been able to locate exactly where it was coming from, but my guesses are it's either an alternator bearing or a leaky radiator hose of something. It's not that loud, but I was wondering if anyone has any ideas on what it is.

Thanks

Could be a cold air/short ram intake.

Nice signiture 02
That was just a rough day for me. I went back and read that reply i put and wow--i have no idea what the hell i was typing. That was my bad, my bad

 

my cai hums pretty loud

 

OPEN THE HOOD <U>START THE ENGINE</U> Then listen for the noise

 

Maavrik. I remember that epic post. I was laughing. It happens dude. Anyway you should get a friend and have him listen for the sound while you coast it. Does it still make sound when you are moving? Which side does it sound like it's coming from?

 

could be a vacuume leak. look for a hose attatched only at one end or a vacuume port unatended by a hose and plug it with your finger to see if the hissing goes away. if it does there you go you found the leak. the problem then is to figure out where that vacuume is to be supplied to. you dont want to just plug it.
