This might be a stupid question, but is there a way to test a AC without a belt on it? My 90 pulsar was in a field for about a year when I bought it. One of the things I noticed was the belt on the AC was gone. Now when pressing the owner (it was his sons car) he said the AC worked but the belt broke. And he never replaced it. Now it looks like a bear to replace so I figured if there was a way to somehow test it before I go through all the hell of putting a belt in. The other belts are fine so no real rush to replace them, but if I do it I will replace all at one time. so just throwing out question for al you guys . Thanks this forum has been Invaluable in working on this thing.

Hmm...well it could be that the belt was old and just broke, or it could be that the compressor seized up and busted the belt...I had a 79 Lincoln and I was driving home one day and my car started overheating bad, pulled over ..opened the hood (with engine still running) and heard this horrible squeeling...the belt on my AC compressor wasn't moving and the belt was smoking like a biatch...Just cut it off and never did replace it the compressor....can you turn the compressor pulley?

yeah the pully turns allright. Its not really a big deal but if its fixable would be nice to have, especially if it just takes a belt LOL

Ok..the pulley turns without the AC clutch engaged, If you start the car and turn the ac on and then turn the car off I think the AC clutch stays engaged so you can try turning it again but I'm not sure if stays engaged when the engine isn't running..Maybe if you start the car and turn the AC on and then turn the key enough to just shut the engine off but leave the power on, maybe this will leave the AC clutch engaged..hmm..confusing ain't it??

just leave the car running with a/c button pushed and turn pulley, it should be alot harder to turn but if it turns smoothly should be ok. you might need to recharge the system though

Well tested the AC today as described, it turned with a little drag when engine was running and AC button turned on, with engine off and AC button turned off it turns real smoothly, So guess I will be putting new belts on this weekend. And give it a shot. Thanks for the info.

if after you put belt on and a/c isn't cold probably jsut needs charged like i said. i dunno how much most shops want for that, i think its usually only $40 but i could be wrong

I just went to the local auto mega-store and bought a super size can of 134a(I think thats they call it now) it had the oil in it too(for the compressor so it won't seize on you)....it also had a cool gauge right on top of the can, very simple to use...My pulsar was already was converted over to the the new 134 stuff...If you have a large blue cap and a large red cap most likely you are converted too...If you don't the whole conversion kit(2 fittings and 2 caps) with refridgerant is about 20 bucks...

as long as you know how to do it and dont blow yourself up that works too. most ppl are afraid to do it cause the R12 can be nasty
