Whenever it rains and I have my car in drive (idling at say an stop sign or intersection), I can hear my car chirp. If I give it gas or shift it to neutral, the chirping sound goes away. When I have the AC on, the car will chirp even in neutral, but will not chirp when I give it gas.



What could be wrong? Could it be a pulley?

Most likely your belts or a belt tensioner (if so equipped). Easy to replace.

I replaced the belt and it still does this. I’ll check out the belt tensioner later. It seems like it went bad pretty prematurely. I mean I baby my car and it has just under 50k on it.

You may not have put it on tight enough. Was the old one giving you problems as well?


#5

Well I’m about 99 percent sure its on correctly. The other one wasnt giving me trouble but someone suggested it could be that so I went and ran with it–wasn’t ready to spend more money on a tensioner and fund out it ws just the belt

Babying the car has nothing to do with the serpintine belt tensioner…they are spring loaded and set to a predetermined spring tenstion. They fatigue over time…Also you will want to pay close attention to any idler pulleys in the belt system…Alternator bearings have a tendency to momentarily elicit a loud squeak…then go away…and back again…the idler bearings do the same thing too.
