Re: Aftermarket AC system for a VW.

Did a search and found a chart and it says that for an ambient temp of 90 it should be between 45 to 55 low side and between 250 and 270 high side and as u can see I only have 32 ls and 212 hs. But I feel afraid of adding more r134 to achieve the values of the chart and damage something. Wellcraft ...

How much torque needed to turn a compressor?

How much torque needed to turn a typical good compressor? On a truck board/site someone reported their compressor required 250 inch-lbs (which is like 16 ft-lbs) to turn, and an off-the-vehicle compressor only required under 20 inch-pounds. I had my 2004 Frontier with 90K and great AC (R134a) handy,...

Re: Corvette A/C rebuild

Re: Ac troubleshooting

Condenser doesn't look so clean to me either. Also make sure the fan clutch is good.

Re: 71 Chevrolet C/10-Pressures good / air only cool?

At 80 degrees outside my pressures were 29 and 160 respectively @ 1500RPM with a fan in front of the condenser. Temp at my vents is about 49 at best. That's running down the road. Tube before and after the POA both feel the same cold temperature. Is there anything else that I should be checking? A ...
