a/c clutch/compressor squealing/screeching

[Yaj Yak]

alright so my gtp is running, and i have been just tying up just lil odd's and ends, the compressor pulley is screeching like a mmofucka. i haven't had functioning a/c in god only knows how long... but this noise is defnitely new.

i don't necessarily want to delete my ac... i'd really rather make it start working again... my question is though- is the clutch replaceable? or the pulley? or would I be better off getting an entire reman compressor?

I just went through this with my black car not too long ago. Replacing just the clutch is possible, but it looked to be more trouble than it is worth. Picking up a used compressor would be roughly the same price and significantly easier.

usually youll get a clutch/pulley assembly together
13mm nut in the middle, a special puller with a tapered ext thread pulls the clutch off the shaft, then a snapring holds on the bearing/pulley assembly and another snapring holds on the electromagnet.

if its got 80+k miles though the front compressor seal may be on its way out so even if you fix it, a recharge could potentially leak out...in that case a reman may be a better option.

if the lines show signs of black death on the inside i'd rec a good used ac compressor from the junkyard that way any debris in the system wont kill a more $$ part

what did you do to end up making the car run?

Mine was because the pulley was rubbing on the clutch so it made a tuuurable noise. At first i bent the clutch away from the pulley, worked for about a month, then i welded the clutch basically to itself, bam. No more noise and the ac worked great!
