If its stock just go in and they'll give you the right one. Take the old one in with you and hold it up to it to see if its the same length.

Thats what I have....its ~9 years old and still looks great. But I do have the Katech tensioner which makes belts last forever.

Are you sure its the belts? How many miles do you have on your idler and tensioner pulley?

Chaos07

for all i know they are stock with 188K miles, and i got coolant on the belts recently and ever since then they will squeek

+1. You'll want to replace the idler pulley, tensioner pulley, and 2 AC idler pullies. Yours are almost certainly dry by now and are probably adding some squeal.

Dayco makes nice AC idler replacements and the main idler and tensioner are widely available. (I purchased a nice set from Goodyear along with their Gatorback belts.)

where can i pick up those pulleys?

Chaos07

Funny thing is its usually when i accelerate and its cold, when it warms up its HARDLY there. but damn its annoying and embarassing

Temperature changes the properties of whatever grease is left in the bearings. I purchased my Dayco A/C pullies from RockAuto and my Goodyear engine pullies from Summit or Jegs. (Can't remember which.)

You may not be able to find the Dayco pulley numbers in a normal lookup, but there is a thread on this site that gives the model number.

Chaos07 I have the exact same problem you described. Changed the idler, tensioner, and belt...No help...Now what? Thanks anyone for help.

- Take the AC Belt of completely. If the noise goes away, you'll need a new A/C clutch.
- If the noise is not related to the A/C, get a mechanic's stethoscope and probe the rotating gear to find out where the noise is coming from.
