I want to remove the air conditioning system in my 88 TII. First of all, is it possible for the home mechanic to depressurize the system himself? If so, how do I go about it. Is there a written procedure on this anywhere, I'm having trouble finding good info.

thanks,
kev

 

You sure it still has pressure?

 

I assume it still has pressure because it still works. I don't understand the a/c system that well yet, I thought they were very pressurized.

 

jsut cut the hard line, dont touch that stuff though, cuz its damn cold. by the way this is illegal but eh it works.

 

You can cut the line, but I wouldn't recommend it. There's a lot of pressure in there. There's a fill port. Should have a pin valve. You should be able to get your hands on a fill kit an bleed it that way, but I would check in with any local auto A/C shop in your area and find out how much it would cost to just have them depressurize the system. That way the gas can be reclaimed and reused if it's not too horribly expensive.

 

So once the lines are depressurized, then the frion will be dispelled? I will be able to remove everything then? How do I remove all the embedded lines going through the fire wall and such? Should I just leave them in?

 

It's pressurized with freon. When you depressurize the system, you are dumping the freon.

 

Yeah, when you open any point in the system, the whole thing depressurizes and there will only be traces of freon. I wouldn't worry about pulling the crap out of the dash. It doesn't really weigh anything, it's a PITA to remove and I believe it carries the water drain from the windshield vent...

 

its illegal to do it yourself if its pressurized... but get a hack saw and saw... and get away fom the leaking gas...

of course in my case, the x years of leaking ac lube meant the system was completely depressurized. I juse used a hack saw and a cut off tool (bolts were corroded together).

Oh... and if you have a laptop, the old ac oil radiator makes a nice laptop cooler

 

Well, I'm really not too keen on hacking the pipe and leaking gas in my garage. I think I'll see how much it costs to have it drained or find a kit to drain it.
