a/c bypass pulley

Anyone here do this on there l99 ls1? I have gone through about 5 of these doorman pulleys and they squeal like hell till they warm up. i have 2 washeres behind each mounting bolt.

l99 ls1? Must be rare..

I'd personally never delete my a/c. call me spoiled but I love a/c

Heh, after the white Caprice introducing me to A/C again and now my new truck that will freeze you, I could NEVER go without it ever again!

well if the compressor is broke and the condensor is damaged it was just cheaper to get rid of it.

lol. Maybe its another 1/2 year thing. I don't know why anybody would want to delete a/c. I did it on my Monte, but it was R12. I'd rather not pay to convert. Personally id try and fix it. Maybe you are tightening the doorman pulley too much. And, is it really cheaper? Sounds like you've already spent a bunch of money after the fact. I'm sure there's guys here that have some extra a/c stuff. A week ago I sold a good compressor to a friend for 20 bucks. You just have to ask.

The caprice has Ice cold R-12 in it, I dont use it all that much because it really sucks gas up more than normal, but im never taking it off unless the bracket breaks somehow. It could be cheap enough to just grab a JY system and fix whats broken.

I took my a/c off the lt1, then again it's going into a truck that didnt come with air, and I'm not gonna try and add ducts and all the b/s. We live in MA not Texas. I'll use my 2/55 a/c on this project!

Hey, its going to hit 90 today and you better believe I'm using my A/C to its full capacity.

not rare you either have a l99 4.3l or a ls1 lol but both are the same thing and Cape cod never gets hot enough for a/c in my opinion

You'd have an LT-1 or l99. LS series engines didnt come out until 97

oops lol typo

Little WD-40 to my doorman worked just fine. Although i'm not sure the difference between the two brackets....

how did you bolt it up thou? what was the washer situation behind the bracket?

I'd you take the actual pulley wheel off the triangle bracket it came mounted on and place the large washer behind the wheel and then reinstall wheel to triangle? The actual triangle shaped bracket should seat against the factory bracket with NO washers in between.

been thinking of doing that also i noticed on my spare one the bearing is larger than the area it mounts to thebracket. same as the one on the car and i bet on the others i replaced. its off by less than a mm. so im gonna try the washer for now but am leaning more towards geting a 1LE pulley.

I got rid of the AC in the 9C1 and thinking of deleting it in the RMW. I've never had any luck with AC once the factory compressor goes. It never seems to last and I got sick of buying compressors. Only use it about 3 times a year anyway (except this year!).

To answer your question, I bought a GM pulley and it doesn't make any noise. It's been on for tens of thousands of miles, not sure exactly how many.

yeah im going for the gm 1le pulley ive heard alot of same problems with mine on others

Love my a/c!!!!!

I love my AC! So much so my old lesabre gets parked in the summer because of its bad compressor
