ENGINE COMPARTMENT UPGRADE KIT

134a

Modern air conditioning systems are more efficient largely because of improved condensers & compressors. Classic Auto Air’s ULTIMATE high performance engine compartment upgrade kit serves as an easy way to replace ALL of your out-of-date, inefficient refrigerant components with modern, highly efficient parts that fit within and connect to your car’s original factory AC system.

 WHY UPGRADE?

  • Stop Annoying Shaft Seal Leaks.The original A6 compressor has a strong tendency to leak at the shaft seal if the air-conditioning is not used on a regular basis; sometimes in as little as two weeks of non-use! This will not be a problem with the modern rotary compressor.

  • Converting to 134a? You get everything needed to convert to 134a except the refrigerant itself. Modern, high efficiency parallel flow condenser AND evaporator, along with a rotary compressor will maximize system efficiency that is lost when converting your system from R12 to 134a.
    (Click here More information is available for converting to 134a)

  • Save Horsepower.Our rotary compressor draws significantly less horsepower of stock A6 compressor; approximately 2-4 horsepower compared with 15-20 horsepower.

  • Increase Fuel Economy. Less horsepower draw means better gas-mileage.

  • Save Weight. The compressor is less than half the weight of stock A6 compressor!!!

  • Have a Lead foot? The compressor can handle 6,000 continuous RPM!

  • NO WORRIES ABOUT FLUSHING ORIGINAL COMPONENTS THAT COULD POTENTIALLY FAIL, SINCE YOU WOULD BE REPLACING EVERYTHING THAT CONTAINS REFRIGERANT ALL AT ONCE!!!

WHAT DO I GET WITH THIS KIT?

  • New Rotary Compressor & Clutch Assembly
  • New Compressor Mount Kit designed for the Chevy V8 engines with the compressor mounted on the driver's side and a long water pump
  • New modern high performance "Parallel Flow" condenser that installs as stock.
  • New modern high performance "Parallel Flow" evaporator that installs as stock

  • New Discharge Hose (from compressor to to pfitting on condenser)*
  • Replacement Filter/Drier
  • Reproduction Filter/Drier Bracket Set
  • Reproduction Condenser Mount Bushings (4)
  • Reproduction Condenser Mount Brackets (4)
  • Replacement Expansion Valve and Refrigerant Tape
  • POA Delete Kit
  • 134a Charge Port Adapter
  • O-ring/Oil Tube Kit
  • ALL THE TECH SUPPORT YOU NEED!!!!

             *Hoses supplied with one end open, along with the corresponding fitting and cutting/crimping instructions. Your local hydraulic shop can provide crimping services, or we can provide the crimping service for an additional fee. Instructions for both options will be included.

WHAT ENGINES DO THE COMPRESSOR BRACKETS FIT?

  • THIS LISTING IS FOR MODELS USING THE STOCK CHEVY SMALL OR BIG BLOCK V8 ENGINES WITH DRIVERS SIDE MOUNTED COMPRESSOR, LONG WATER PUMP AND FACTORY A/C CRANK & WATER PUMP V-BELT PULLEYS

  • DOES YOUR CAR HAVE A DIFFERENT ENGINE? Please contact us for more information.

CAN I INSTALL THESE PARTS MYSELF?

  • The average hobbyist can install without difficulty. General rule of thumb is if you change your own parts, you can change these parts. It is recommended, however, to have the system evacuated & charged by a professional.

  • No other specialized tools or knowledge is required for installation of parts.

  • This kit is designed for use with the newer 134a refrigerant.

CONVERTING GENERAL MOTORS CARS

TO 134a

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement.  Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

 

1955-61 Models with Hot Gas Valve (aka By Pass or Hot Gas By Pass Valve)

The Hot Gas Valve is most often found mounted to the compressor, though some cars have it mounted back near the evaporator. The front half of it looks like a bullet. (Click here for a typical photo)

Minimum Requirements

  • Change or restore the filter-drier.
  • Drain the compressor oil and recharge with 134a compatible oil. (PAG or Ester Oil)
  • Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)
  • Replace or restore all rubber hoses with barrier hose.
  • Rebuild hot gas valve.
  • Install 134a charge port adapters.
  • Charge with 134a between 70-80% of the original R12 charge amount. Note: Hot gas valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.
  • Replace any o-rings with 134a compatible.

Recommended:

  • Install hi/lo pressure switch

HELPFUL HINTS

  • Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.
