    Exclamation Broken AC Pulley disk

    Hello Comrades,

    Hope everyone is having a great summer. Pretty much my first post here

    Heard a pretty nasty metal grinding sound coming from the engine bay as I was rolling in to work this afternoon. 09 WRX

    Opened the hood and saw it right away:

    Did a little bit of research and seems like that the AC Pulley disk that's broken? (am I right?)

    If that's the case, is it driveable to the dealership? A while back I heard someone say that I could just cut the belt?

    How does this crap happen, is this typical?

    That is the compressor pulley. Remove the belt and do not use the defroster or the A/C.

    The compressor clutch fell off, it happens from time to time but is perfectly safe to drive, although your a/c won't work until it's fixed. It's sometimes cheaper to replace the whole compressor.

    I have seen this a couple times on these cars....might be worth a call to the dealer to see if its covered. depending on your mileage of course...BTW those belts are a SOB to replace, Ive done a couple of them...when you buy the $60 belt from the dealer they give you a little wedge which is supposed to aid in re installation...
