WHAT ENGINES DO THE COMPRESSOR BRACKETS FIT?

  • This kit is designed for use with the newer 134a refrigerant, though we may be able to provide an R12 version of this kit if desired. Please CLICK HERE for information on converting R12 systems to 134a

  • Stock Small or Big Block Chevy V8 with short water pump and compressor mounted on passenger side (right-hand) of the engine.

  • PLEASE MAKE SURE THE ENGINE FITS WITHIN THE GUIDELINES LISTED ABOVE.
  • UNSURE? Please call or EMAIL with questions.

  • ENGINE BEEN MODIFIED? Please call or EMAIL with details before purchasing


    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. Hose Crimping instructions can be downloaded by CLICKING HERE.

  • Other than crimping one end of the hoses and charging the system, no other specialized tools or knowledge is required for installation of parts.

 

  • This kit is designed for use with the newer 134a refrigerant. It is important to make sure the evaporator, condenser and liquid line/hose are either changed or flushed and clean of contamination before installation and charging of the system.

 

 


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.
  • Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

 

1962-66 Models with Suction Throttling Valve (aka STV)

The suction throttling valve is installed on the evaporator, near the firewall.(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)
