Question about 2002 Mitsubishi Lancer

1 Answer

2003 mitubishi lancer

When the ac is on the car makes a noise kind of like squeeking, but louder. when you turn off the ac it is no longer evident. The ac works well with no noticeable problems. wondering if it is a belt or something or the ac compressor. I'm shying away from taking it to the dealer as I don't want to really know how much it is going to cost, but would like to find out the problem.

I think the noise is most likely from the drive belt, the reason it makes noise with the AC on is that it takes 5 horsepower or more to run the AC compressor, this puts a heck of the load on the belt, as the belt ages it gets hard and polished, this causes slippage, and squeal, esp when a load is on the belt like the AC.

2.0 Liter, 2003 Rav4. Car had a ticking noise, Toyota replaced serptine belt and still makes ticking noise. Toyota says its lower engine rod bearings. I used stethascope and noise seems to be coming from...

big end bearings( lower engine rod bearings to confuse) knock at idle and get louder with rpm
if the noise changes with rpm and you are hearing it near the ac compressor then it could be the ac pulley bearing
test if it is the compressor by listening and then turning the ac off the pulley will still spin but the compressor stops
if the noise remains , replace the pulley bearings

When I turn the AC on in my 2003 Honda Odyssey, a squeeking noise comes from under the hood. It sounds kind of like a belt. Can you tell me what this is?

The belt is either glazed (old) or is loose, needs to be tightened. Your best bet is to buy a new belt and install it to the proper tension and your squeeks will be gone.

Old car noise or trouble?

i have seen a lot of cars make noise when you turn the wheel all the way one way or the other and usually it is either the upper or lower ball joint. it will be louder when its really cold. i would jack the car up and see if there is any play in the ball joints.

I am sure the issue is belt related noise, it must be inspected not just for the belt but the idlers and pulleys the belt runs on, they may have a worn bearings or other damage, if all looks good then and only then change the belt. I hope this info is helpful.
