Re: A Problem with New OEMTOOLS AC Service Set

Sounds like the supplier sent the wrong hoses. The ends that connect to the gauges should be 1/2- inch ACME and not 1/4-inch SAE Flare.

By the way, the air vacuum pump pictured won't pull a sufficient vacuum for a thorough evacuation.

Re: 1977 saab 99 retrofit

I agree with the previous comment. You should bring the car in to a professional A/C shop...preferably one with vintage Saab experience...to sort-out this setup and to get the system operating again.

Try contacting Cold Hose in Ocala, Florida. They might be able to fix you up with a suitable fitting.

Re: AC not cold and excessive moisture/water under the car

Your Trailblazer is around 13 years old. If the A/C system has never been serviced, it's probable that the insufficient cooling issue you're experiencing is due to a low refrigerant charge. As already mentioned, you can't determine the refrigerant amount by pressures. What's needed is to recover the...

Re: flushing method

Okay...we've zeroed-in on the oil amount. Great! Both Old Air (7 ounces of PAG 46) and Tim (220 cc or 7.4 ounces) are very close. I would go with what Tim said for a slight bit more oil, which IMHO won't hurt anything. Also, drain and refill the compressor once, as Old Air suggested. Based on the ne...

Re: flushing method

John TY for the help, I have not found what is the proper oil and capacity for the compressor Pro6Ten, A6 copy, using 134A I have look but not in the specs I looked at. I can't find that oil spec, either. But I would bet it holds the same amount as the GM A-6...10-11 ounces. You could try calling O...

Re: Need expert help on 1985 Corvette ac overhaul

Corvettes aren't known for outstanding A/C performance, at least the front-engine models. I don't know about the 2020-on mid-engine cars. So IMHO, 47 degrees at the center vent on a hot day seems pretty good.

Re: No oil in the condenser

JohnHere, Many thanks for such detailed answers to my many questions. Unfortunately it is too late to take action on most issues, since in my Civic there is no easy access to many of the AC components, including the compressor. But I'll make sure that the pressures are in spec and that there are no...

Re: Need expert help on 1985 Corvette ac overhaul

Installed Ester oil 3 oz in compressor, 2 ounces in Dryer, 1 ounce in condenser 1 ounce in evaporator Oil amount and distribution sound correct. Not that it won't work, but I'm curious why you decided on ester oil instead of PAG. New equipment/ hoses/Flushed, Dried and Vac. Blew shop air through al...
