DIY A/C Lines
Collapse

Follow-up on my first post. This past weekend I replaced the dryer, expansion valve and all of the o rings in the system. I took the car into an A/C shop today to have the system vacuumed and filled with r134. No leaks and I have cold air. I think this will be one of my favorite mods beyond the S50.
Also, I have read several posts about needing to run a signal wire to the DME to maintain idle with the A/C on...I didn't do this and have no issues with my idle (knock on wood). Good luck to everyone on adding A/C and I hope you find my DIY useful.

did any of you guys just try reversing the a/c line? i think it fits...i'm going to try this weekend to confirm it. i gotta get a/c in before traffic kills me.IG: deniso_nsi Leave me feedback here

Just wanted to bump this up as I will be tackling this once i get me some E36 A/C lines. Chuck, how long did it take these guys to get the parts to your door?IG: deniso_nsi Leave me feedback here

not long, they arrive in a few days.
in my experience, there wasn't enough room to put the splicer in the hose from the compressor to the condensor and still get it to bend enough. i ended up cutting the fitting off the e36 hose and welding it onto the e30 hose. the steel tubing is thin and it was tough to weld but my brother in law was able to do it.
i haven't charged the system yet but all the hoses are hooked up. now onto the wiring....______________________

might be a stupid quesiton, but...what about the wiring?
it seems the o/p just hooked everything up and it worked.IG: deniso_nsi Leave me feedback here

o/p also mentions that he didn't have any issues with the idle, im willing to take a chance to see what happens and if it is an issue then i will have no other choice but to address it. for now though, i just want cold air to circulate.IG: deniso_nsi Leave me feedback here

I know there are several e36 lines that run from the compressor to the condensor at different angles. The original M3 fitting is angled in a way that it points straight down to the ground (Obviously this won't work). I found an e36 line at the pick-n-pull that had the correct angle to install the splicer in the hose. I know others have used the hose from a 91 318is and although a little long, can be made to work.
As far as idle issues. I do have a slight idle issue as the compressor cycles on and off, but no stalling and not really much of an issue. If I blip the throttle it holds steady.
