Hi all,

I started having a squeak in my engine bay about 2 months ago.
I figured it would be the cold weather, (it went away after warming up), but as of recent.. it just keeps squeaking!

I looked at the belts and they look fine, I'm thinking of cutting the A/C belt to rule that out.
But I think it could possibly be the tensioner thats at the top left of the engine bay- the one closest to the battery.

I was checking to see if I could tighten the pulley that is on it - and the whole tensioner actually moved a bit 0_o

I added a pic, does that look like its loose?
The squeaking increases as I accelerate.

that's your main belt tensioner, it could be going bad and squeaking or it could be one of your A/C idler pulleys or your A/C tensioner itself. Your best bet is to spray each pulley while its running with a little bit of WD-40 or some other lubricant and listen for it to go away. Then you know where you gotta go from there. My instinct says it's one of your idler pulleys since my car was doing the same thing. I just removed them and regreased the bearings and they shut up. lol

My guess is the idler pulleys on the bottom next to the AC compressor. You can re-grease those instead of buying new ones.

Belt can't be too tight since the stock tensioner/s are NOT adjustable.

Once I get off work today I'll cut the A/C belt, that way I can rule out anything having to do with the A/C side of things.

I planned on getting new belts on the 31st anyways.
Yeah I bought a can of WD40 and sprayed here and there and got it to shut up on the main belt, so I think its probably the main one.

Good heavens Batman! Whatever you do, DO NOT spray the pulleys (as suggested above) with WD-40. WD-40 is a low durability penetrating oil and the pulleys need grease. WD-40 should only be used to loosen rusty bolts on a car and nothing else. If you use it on a good pulley, it will dissolve the good grease that's there and will cause the good pulley to quickly burn out on you.

The best way to find a squeaking pulley is to use a mechanics stethoscope:

You can get them at many stores and they typically run $5-10.
