yea, not tooo much money, ask google

theres also R12 substitute available but i have no experience with it

 

ok, so i went out and bought the r12 to r134a converter and had someone start charging it. come to find out, the compressor is broken. apparently, the previous owner tried messing with it, so now it doesn't work.

just thought i'd update...

 

hmm i saw today on my front fan that there is a label that says r134a. so probably my ls was converted before?

 

If it's a 1990, 1991, or 1992 model, then yes.

 

mines a 93 though

 

1993 and up came from the factory with R134a. There's nothing to convert.

 

Even if you have a '90-'92 there is no need to convert since R12 is cheap and plentiful on ebay and so are the R12 can tap valves and charging hoses.

Your local dealer and AC shops won't tell you this because they'd lose business if they did.

 

CORRECT

 

How can you figure out which version you have?

EDIT: Some people said 93 and up all had R134a, but this didn't seem like a consensus.

 

r134a systems use quick connect couplings, r12 use externally threaded schraeder type valves

 

Consensus or not, it's a fact.

 

suneet, try checking on the engine fan in front of the car, behind the grill. there should be a yellow sticker that says r134a in the background.

 

The system was completely empty (no pressure or anything). I noticed that when I was replacing the service valves that the high pressure end was completely loose! So replaced the valves and I just put in 3 cans of R12 and some oil to recharge my system today. AC is blowing a smooth 58 degrees Fahrenheit (tested).
