Summer is coming so I need AC in the south. I recently bought a 1987 R10 5.7l from a local original owner estate sale. The Harrison R4 AC compressor is locked up. If I turn on the AC the belt squeals. I don't see refrigerant leaks and I pressed the nipple on the dryer and gas escaped, so I think its still charged. What should I do? Replace the compressor and recharge with R12. Replace the compressor and dryer and recharge with R134. Replace everything and recharge with 134. Something else? I've seen kits with compressor, tube filter, oil, o-rings, dryer, but I'm not sure how to verify I buy the right kit? I've never worked on an AC but I've read alot about flushing the system, youtube videos, replace orifice tube filter, replacing dryer. It looks like alot of it is straightforward bolt on, but I know there has to be more to it. What would you do?

Not quite sure what I'm gonna do with it yet. So I just grabbed up a 1980 chevy 3/4 ton 454 manuel 4x4 I'm not much of a "small truck" guy but I've had a ton of people already stop at my house trying to buy it. So the truck itself is Rusty the doors and fenders are great everything else is junk . I bought it for a possible frame swap to go under my 1956 caddy project (mad max style) But I'm being told this is a much wanted truck in this configuration. Can you guys tell me if this truck is worth getting a new cab and bed.... And redoing it or should I just move on to my project. I was told the t case is chain drivin I haven't got to looking yet what I have the 454 was just put in it the recent owner blew the 350 apart mudding the truck the 454 has 56000 miles on it came out of a motor home . I just don't know what to do with it . A little about me ... I restore /modify anything I can get my hands on . currently building a 1938 caddy was a 4 door now a 2 door 3" chop shortened body suicide doors air ride small block chevy 5 speed cars name is sinner . I'm also helping my helper build his first car 79 camaro I bought for him out if a junk yard . There's a few other cars kicking around here like the 56 caddy mentioned above and a 67 lemans getting a 4.8 Ls twin turbo setup And now this chevy just got here . I could go ether way on it as I wanted a old bulldozer to put under the caddy but this truck setup seems Stout!

The partial VIN has me puzzled though as it doesn't seem to be in the right format? Anybody got any theories? Thanks Graham Read More | Write Comment New to GM 4WD Pick...
