E30 air conditioning

[6670charger]

My E30 needs a charge to the A/C, but still has the original style refrigerant.  I know I'll have to have that evacuated from the system and need a new fitting for the R134.  My question is which fitting I need to get to replace the current one?  How hard are they to change?  Is this something I can do once the old refrigerant is removed?

 

Thanks.

No need to convert. 

 

This stuff works great

 

I bought a kit on Amazon 3 years ago for around $75 that included 2 cans of refrigerant, a can of oil, and the gauge/filler.  It is still working fantastic.

I'd go with what Snap recommends. It's very popular with the E28 guys (same A/C system) too. R12 is a better refrigerant than R134a, so it would be better to stick with it or a substitute.

Its certainly the way to go if you want to save big money!!!

R12 is more dense and can get a colder. Its less likely to leak. I dont see R12 locally, but with a recent law change, you can buy it online in small quantities. Most cars take about 2 lbs. Its good to put oil in there and some dye if its leaking a little. Dont use any type of stop leak.

That sounds like an awesome suggestion.  My indy told me it would cost about $200 to change the fittngs, evac the R12 and put in new refrigerant.  $75-100 is a much better deal, and sound like a better solution.  Figured you'd all know some good info.

 

How many cans of this stuff is equivalent to 2lbs?

 

Thanks!!
