The First Mustang

Have to admit to being a little entranced with some of the Mustang myth and mystique that has been reported during this year’s celebration of the 50th anniversary of the Pony’s introduction. There’s an article we read recently on the Henry Ford Museum blog detailing the history behind the first serialized Mustang (100001) and its accidental original owner, Captain Stanley Tucker, a Canadian airline pilot. 

POA Valve Q and A

Vintage air conditioning systems in most mid 1960’s to mid 1970’s GM vehicles and some 1970’s Fords include a POA valve.  POA – an abbreviation for Pilot Operated Absolute – valves are suction valves used to prevent the AC system’s evaporator from getting so cold that it freezes. In some air conditioning systems, this function is handled by a thermostat. In most mid 60’s to mid 70’s GM vehicle air conditioning systems and on some 70’s Ford systems a POA valve was used. Frigidaire and Delco were the primary manufacturers of these valves.

Auto Air Conditioning Evacuation: Not Just Testing For Leaks

One of our favorite “Go-to-a-licensed-professional-for-AC-system-charging” stories involves a guy we spent more time than we care to admit troubleshooting before it became apparent that he was releasing the vacuum before charging. His thinking: “I checked for leaks, now I’m moving on to the next step.”  He was not only evacuating and charging without a license but without any understanding of what he was doing. Please, if you are not a licensed AC professional, do not evacuate/charge on your own. Go to a licensed professional. It’s worth it to get it done right.  That said, we’ve run into many experienced car guys who don’t really understand evacuation and decided a quick summary would be helpful to even licensed AC professionals.

Six-Steps – Hand Charging A Fixed Displacement Compressor with 134a

Last month we covered charging stations. This month, it’s hand charging. Commercial installers of our kits as well as professional, licensed air conditioning repair facilities have asked, so we have developed a six-point checklist for hand charging a FIXED-DISPLACEMENT COMPRESSOR (Sanden style) system with 134a refrigerant canisters.

My mechanic says I need to replace my AC filter drier. Do you agree?

Question: My mechanic told me my compressor is locked up and it needs to be replaced on my 1965 Mustang.  He also told me I need to replace the filter-drier and flush the system at the same time in order for him to warranty his work. Why must I change my drier if all I need is a compressor?

Answer: Think of the filter-drier like you do the oil-filter for your engine; anytime you do an oil change you also change the filter.  The same rule applies for any air-conditioning system.

Let’s back up a moment and explain the functions of a filter drier.

8-Steps – Charging A Fixed Displacement Compressor with 134a

Commercial installers of our kits as well as professional, licensed air conditioning repair facilities have asked, so we have developed a procedure and an eight-point checklist to be followed for charging a FIXED-DISPLACEMENT COMPRESSOR (Sanden style) system with 134a REFRIGERANT from a CHARGING STATION.  (Note: procedures are different if you are HAND CHARGING with individual refrigerant canisters or if you are NOT using 134a refrigerant).

Why does my A6 compressor keep leaking & slinging oil?

We get a lot of questions regarding General Motors’ A6 “long-style” air conditioning compressor and leaks.  We are focusing on the A6 because it is notorious for leaking, but our advice here applies to any vintage air conditioning compressor system.  We last wrote about the issue of A6 compressors leaking oil from the shaft back in 2011 so it is probably time to revisit the issue.

A customer recently described his specific situation like this: “Over the last 5 years, I’ve replaced three rebuilt long style compressors on my 69 Chevelle.  I only drive my Chevelle a couple hundred miles a year, and it seems that every time I drive it, the compressor pulley ends up slinging oil under the hood and leaking refrigerant at the shaft seal.  I finally decided “to heck with it,” and replaced it with a new one, only to find the same problem.  Why can’t I find a decent A6 compressor, either new or rebuilt?”
