Chevy G-Body OEM Air Conditioning – A Failure Corrected

July 15th, 2014

The factory R4 compressor that was originally used in the 1978 through 1988 Chevrolet model years (affectionately referred to as G-Body cars) has proven to be notoriously unreliable and is frequently cited by mechanics and seen by CAA technicians first hand as a common cause of A/C component failure in GM G Bodies. Upgrading to Classic Auto Air’s direct fit rotary compressor will solve this likely reason your A/C is inoperable. The direct fit rotary compressor will also reduce horsepower draw, and allow for operation at up to 6,000 RPM. Even if your current compressor is still holding on, the OEM condenser design and R12 refrigerant are significantly out-of-date; upgrading to Classic Auto Air’s high performance direct fit condenser not only makes converting to 134a easy, but drastically improves your overall system performance.

Do I Need To Add Oil To My Air Conditioning Compressor?

July 15th, 2014

Customers often ask whether or not they need to add oil to an air conditioning compressor they purchase from us. This question comes up because people want to avoid poor cooling or failure problems resulting from improper oil levels. Fortunately most people realize the harm to the system and potential danger of running an AC compressor with no oil. Read the rest of this entry »

AC Installation Tips – Loose Fit FIRST!

July 15th, 2014

From our mailbag – here’s a recent email from Ray:

I just installed my new rotary compressor using the York to Sanden compressor & u-shaped idler adapter brackets you supply in your kit. I attached the adapter bracket to the mount and tightened the compressor to the adapter bracket, then tried to install the u-shaped idler adapter bracket. I could not seem to line up the mount holes on the stock idler bracket to the new compressor. What am I doing wrong or do I have the wrong adapter mount?

Your wish is our command!  With the success of all of our D.E.R.

Turn Of The Screw – Adjusting Tecumseh Or York Compressor Service Valves On Your Car’s AC

April 20th, 2014

Working with vintage air conditioning systems is a labor of love for us and we like to share tips and tricks-of-the-trade for maintaining these old systems.

A recent customer of ours purchased a compressor and installed it on his 70 Ford Maverick and brought the car to his a/c mechanic to have the compressor charged with refrigerant.  Shortly after, he called us in a panic when the pressure relief valve on the Maverick’s compressor opened during the charging of the air-conditioning system, spraying oil & refrigerant throughout the car’s engine compartment.

Two Icons Meet Again in New York City

April 8th, 2014

mustang-empire_state__64Later in the month of April, I’m heading to New York City to see two icons brought together who haven’t met in decades. No, I’m not talking about seeing Rocky meet up with Apollo Creed on Broadway! (Although I may take in that show also.) I’m heading to NYC to see the brand new Ford Mustang at the top of the Empire State Building. And this 2015 Mustang will be brought up the same way it was in 1965 – piece by piece in an elevator.

Replacement Aftermarket A/C Defrost Duct for Chevelle Years 1970, 1971, 1972

March 26th, 2014

Chevelle Aftermarket Replacement AC Defrost DuctWalls Are Twice as Thick as Original GM Part# 3963756

Question: What do you get when you mix thin gauge plastic with radical temperature shifts from hot to cold and back again? Answer: Warping and cracking!

In the auto restoration industry, there has been a history of scrapping OEM air conditioning ductwork in vintage ’70-’72 Chevelle, Monte Carlo and El Camino models because the duct had snapped off flimsy mounts, or developed cracks. So our engineers decided to develop our own replacement duct and while we were at it, figured we could address the hot/cold warping issue head-on. Read the rest of this entry »

Air Conditioning Upgrades for Mopar B Body Cars – 1968 – 1970

March 19th, 2014

Can aftermarket air conditioning components improve on OEM design?  Factory original purists may balk, but sometimes original dashboard designs can be improved upon. A case in point is our in-dash air conditioning and heater controller for B Body Mopar cars built in the years 1968, 1969 and 1970. As with all CAA vintage air conditioning aftermarket products, we pay close attention to the details of the original design. It is part of what has made Classic Auto Air the aftermarket air conditioning leader for over 40 years. Read the rest of this entry »

1969 GTO Upgrade: Cable-Free Electronic Air Conditioner Controls Now Available

March 5th, 2014

The 1969 Pontiac GTO has gotten its own Perfect Fit air conditioning system with DER – Fully Electric Controls. Pontiac enthusiasts everywhere will be cheering the fact that the previously inaccessible blower switch has been completely replaced so that no modifications to your firewall are needed. In the 1969 Firebird and 1969 GTO, Pontiac mounted their air conditioning / heater blower switch in the in a location that was inaccessible and you literally could not replace with an aftermarket style switch. Without a blower switch, there was no way to control your blower speed!  Because of the original General Motors design, like most cars of the era used a metal-sheathed cable to mechanically operate the air diverter doors. After roughly 50 years of use these cables rust and stiffen it becomes quite impossible to operate commonly breaking a lever in the control head itself. Read the rest of this entry »

Should I Update Air Conditioning Components or Restore My Classic Car’s Factory Original A/C?

December 20th, 2013

When it comes to classic cars, original only happens once and there is something to be said for maintaining and refurbishing factory assembly line original components. Yet
upgrades to improve performance, and driver comfort may make more sense depending on the condition of your vehicle and how (and if) you drive it. This debate has no right or wrong answer, but at the end of the day, the decision to restore factory original AC components or install a new air conditioning system depends on a variety of factors, including resale value and use of the vehicle.  Read the rest of this entry »
