Re: Weak Compressors, or bad orifice tube?

The system capacity for that GW is 26 ounces of refrigerant, and 7.5 ounces of PAG 100 oil. You are undercharged on refrigerant, and at an unknown oil charge level. When you replace a compressor, drain the NEW one. It is unlikely that there was a full 7.5 ounces in the replacement compressor. Testin...

Re: Want my 1956 Imperial to be a freezer in the summer

Hopefully you still have a Bridgeport within reach. There are plenty of compressors out there to choose from. Pay attention to the drive ratio for the diesel. The average compressor can spin to 6,000 rpm, some are ok at 7500 on the rev limiter. Under driving the compressor from an engine that spends...

Re: 1993 Honda Accord weak AC after total rebuild

Lavarider: Those pressures at 1500 look very good for that system. 30psi on the R12 system is about perfect, 35f suction. The TXV is fine. You probably have a reheating issue, or air is bypassing the evaporator core. Sometimes when you replace an evaporator core, a foam seal has disintegrated to the...

Re: Want my 1956 Imperial to be a freezer in the summer

Compressor capacity on automotive compressors is generally someplace below 4 tons. A Sanden 7H15 is able to make 2.13 tons at maximum capacity. The GM V7 compressor makes it to 3.98 tons capacity maximum. Running two compressors with separate systems will work. The larger TM31 compressors used on am...

Re: 2000 Excursion Rear AC Issues

I think you are there. the FSM shows 50psi low side pressures in some conditions. Just a lot of heat to recover.

Re: 1961 cadillac conversion

Yep. GM kept that manifold footprint across several compressor platforms. The R4 began to replace the A6 in 1975 for some GM cars. It was widely used for the next 20 years. I believe the 1996 Buick Roadmaster was the last production car with the R4. Then came the parade of compressors - H6 DA6 HR6 V...

Re: Mark IV AC evaporator history questions

Sorry we hijacked your thread David.

A friend of mine is building a 1959 Chevrolet station wagon, and he is doing just what you are - adding an original knee-knocker.

I am trying to convince him to put an evaporator in the back too. We are stumped on exactly what that should be however.
