In 1992 GM was still using R-12. A VERY expensive thing to have charged these days. And certainly not doable for a DIY'er as you need to be licensed to even get R-12. The easiest and cheapest way is to get the retrofit kit to convert your car to R-134a. It's about $45 at AutoZone and includes compressor oil, freon, fittings and the charge hose. Now...the "recommended" way to do the conversion is to replace the compressor, filter/dryer, rubber o-rings, etc. I have converted several cars using nothing more than the kit and they've lasted for years.....but I make no guarantees.
Under the air filter compartment.
How do you convert the ac in a 1992 Chevy lumina
it should be on the drivers side near the battery. somewhere on that side of you car.
The AC recharge valve on a 2001 Chevy Impala 3.4L V6 is near the firewall. It is the larger of the two tubing.
Was unit evacuated before recharge after compressor replacement?
r-134a
r 134a
on the low pressure side
Fittings for 134 freon
Only when the AC is on.
Is this the same on a 97 model Lumina It is right under the air filter box. Take off the diagonal brace and then take off the filter box.
recharge gauge shows pressure of 70 psi
