#59206 hey all, i have a LS-swapped EJ2, recently installed a ac belt that the previous owner didnt put on, teh a/c works but only on cooler outside temperatures....but my question is this:

been having this problem thats driving me crazy....ok, when i drive, it whines like it has turbo or somethin like that.....when i have a/c on, teh belts starts to screech like a lil girl :lol: even sometimes at idle....

some workers that works next to me noticed today when i started up the car he's telling me that the a/c pulley is bad and he says ill get the whining on low rpms (1000-3000 rpm) and he was right. i was wondering if changing out the a/c pulley be easier on install or changing out the compressor.......any help would be greatly appreciated :thumb:

#59233 the belt might not be tensioned enough either.
