squeeking noise?, alternator? please help Options

[tim86]

Hey guys I recently noticed a chriping/squeeking noise coming from the pass side under the hood. This only happens when above 1k rpms and this fluctuates while accelerating. When listening under the hood it sounds like the alternator whining a bit. Is there anything else that could make this noise? Just trying to troubleshoot and save up money before i take it to the shop... thanks guys

Could be belt, pully, altenator, or PS pump. The trick i've used, get a pole, and put your ear on one end, then point the other end at noise and move around til you find where its coming from. Obviouslly where its louder is the location. Try not to hit the belts either with the pole...that could hurt. Then you know exactly where the squeek is coming from. This is how I fould out my PS pump resevoir was leaking and causing the pump to work harder if at all, and causing the squeek.

Also works with a screwdriver, or anything else you can find.

Sounds like the belt. With the car off, push on the belt between pulleys. Should have about 1/4" of movement. Tighten if has more slack than that, or replace if frayed/cracked.
