LOOKING FOR A BOOK, AIR CONDITIONING STRATIGIES

[Bob C.]

Anybody have a copy of "Air Conditioning Strategies fot the 63-82 Corvette" written by Michael J. Davis ?
It is out of print and I have been unable to find a copy.
If you see my posting from @ 10 minutes ago re; my 67 ac problem you can understand why I want a copy so badly.
Would be willing to buy, rent or borrow a copy with a deposit if needed.
THANK YOU.

After reading your earlier posting ... I'm not sure the book will help ... as I remember it ... it wasn't so much about the cooling system as it was about the cooling environment ... duct, flap valves, insulation, etc... but your still welcome to borrow the book if you want.

Bob:

I agree with Mike regarding this book. I remember reading it many years ago, and did not find it particularly useful for solving my air conditioning problems.

Suggest that you go to www.autoacforum.com/ and look through the sections AUTOMOTIVE AIR CONDITIONING FORUM and AUTOMOTIVE AIR CONDITIONING PROCEDURES, TIPS, AND FAQ. Extremely helpful information to anyone with an air car.

Looking at your previous post, it appears to me that you may have a problem with your POA valve sticking, or possibly with some air (non-condensibles) in the system. According to the 1967 GM Service Manual, the POA valve should hold a constant 30 psig on the outlet of the evaporator under most or all conditions. There is a slight correction from this value depending upon elevation. The GM Service Manual has an excellent section on air conditioning and troubleshooting. You should purchase, if you do not already have one.

During the replacement of various ac components, did you add any refrigerant oil to your system? If not, this could be a problem. At one time, my POA valve was sticking and causing me problems, but I was able to get it free by adding one can (2 oz) of refrigerant oil through the POA (and compressor) suction connection. This oil is available in small cans that are pressurized with R12 refrigerant.

Also, many people do not know that the POA valve can be adjusted to optimize evaporator pressure and system cooling. However, this requires that the system is empty and the POA disconnected. Classic Auto Air knows how to reset the POA and has the equipment to test and verify correct operation of the valve. If you continue to experience problems, this may be needed to ensure that it is working correctly.
