Go have your system drained at an a/c shop. Its cheap and you can have them recharge it after.

thanks merv. the block that screws into the back of the compresson on the 97 looks just like the ls1 block. I am wondering if they will just swap. i will take a picture tomorrow.

And if they do swap can i just unbolt it without freon shooting all over the place ?

Mine had a leak so it pretty much drained itself. I guess if you had some pressure built up somewhere and you needed to get it out, just take it apart slowly.

Most likely your V6 compressor has the same back end as the LS1 compressor does; no point in designing and building different "peripheral systems" for very similar platforms. The LS compressor back end where the block fitting bolts on has 2 ports, 16mm diameter. The block fitting uses a .050" thick gasket, and a .150" thick gasket between the block fitting and the compressor as the counterbores on the back end of the compressor are different depths (keeps factory assemblers from mounting the hose assy backward).

Just crack a block fitting at the condenser or drier, and let the R134a escape slowly. The A/C system when cold & not running is probably less that 200psi. You can get a mobile A/C guy to come to wherever you are if you want to do the right thing and capture the gas. The mobile guy is handy when you want to re-charge it.

I agree with Steve.

Also buy a compressor o-ring set. Every one I've got from advanced auto was a Factory Air brand which is made in USA.

The good part is it comes in a kit with all the different o-ring thickness combinations.
Just make sure when you bolt it up the block stays parallel with the compressor. If you have the wrong o-rings it will go crooked and leak.
