1994 GMC Suburban

eschnell on Mon June 16, 2008 6:51 PM User is offline

Year: 1994
Make: GMC
Model: Suburban
Engine Size: 5.7L 350
Refrigerant Type: R-134a
Ambient Temp: 80 F
Pressure Low: LEAK
Pressure High: LEAK
Country of Origin: United States

I got this suburban knowing there was an A/C problem. I checked the pressure and it read "0", so I started looking for a leak. I could see that there were new hoses installed and a new radiator from the previous owner. I found the leak at the front and back seals of the compressor. I am pretty mechanically inclined, so should it fix it myself, take it to a shop or roll down the windows. $$$ is a huge factor with gas prices these days.

Thanks
Eddie Schnell

I bought essentially the same thing in Nov. 2000 - a 1994 GMC Sub with dual AC that had a bad compressor, loud and visible oil leak, but AC still worked. I've had the compressor, accumulator, and orifice tube replaced twice since, by a mechanic. It works very well, even in Arizona heat (112F today). Yes, mine has a small leak in the high side AC line, am contemplating replacing that if I need to recharge this summer. My mechanic says not to go with rebuilt compressor on this, has used brand new R4 type. Actually, I'd consider swapping to a Sanden compressor for this, contact board sponsor ####, there should be a conversion kit.
