ricangsxrdude · 08-25-2008, 09:36 PM

I'm trying to locate the A/C charging port on my 86 MkIII.. Also if anyone knows what type refrigerant I need that would help out a lot too.. Can anyone help me out??? Thanks a lot!! Also I'm looking for spare parts for my car (especially the passenger door outer trim in brown).. Thanks for the help!

I have the same issue with my 88. A refrigeration guy can do it, but I dont know if the dealerships will anymore because of the old coolant (CFC's).

Anyone had to do this on a MKIII yet?

I will post here if I figure it out.

You can refill it from here

using freeze 12. Freeze 12 Freon Replacement: EPA Approved!

I looked around as well. Being as I am in Canada, I think retrofitting or retrofitting to use Freeze12 is my only option. Here it will cost me 400-500 to retrofit my 88. Bah! I would do it myself.. but this isnt something I want to dabble in. Looks a little dangerous.

I noticed that there is a connection that looks like a filling cap near the trunk release on the front of the car. It directs to a sight glass so I was wondering if that is the right spot. Can anyone give me any pointers or am I looking in the wrong direction?

Thats the high side port, fill into there and youl explode a refrigerant can in your face... Dont do this unless you are experienced.

So I should do it from the port near the battery then huh? Like on the picture?

I think you shouldn't do it at all without a good knowledge of how the system works and how to diagnose it. A/C work isn't for the inexperienced, you've got to learn it all by the book before you can go out and work on a car, it can be very dangerous. And your car needs R12, a refrigerant you cant even buy without a 609 cert.

So pretty much it would be pointless to get the R-134 conversion kit then huh?

Well.. as said.. if you want to become an expert, go for it.. but first become the expert. Its just a dangerous area to play if your a novice.

Me, personally, Im just having it done. Would rather spend the 500 to have my conversion done properly by a trained person. In the end, its just safer and wont cost me more due to "my mistakes".

Having said that, of course... I dont think its that hard providing you study what your doing prior to doing it, and make sure you have all the tools. The write-ups are pretty self-explanatory and I thought it wouldnt be that hard to do correctly.

However, I still make math mistakes that I am 100% positive they are correct until after I double check.
