Everything you need to convert your factory air-conditioned 76-79 F-Series Ford Truck / 78-79 Bronco from the original compressor to an ultra efficient rotary compressor and parallel flow condenser with 134a.
Modern air conditioning systems are more efficient largely because of improved condensers & compressors. Classic Auto Air’s high performance engine compartment upgrade kits serve as an easy way to replace your out-of-date leak-prone compressor & antiquated condenser with an improved high-performance parallel flow condenser and rotary compressor to connect to your car’s original factory AC system.
Stop Annoying Shaft Seal Leaks. The original York & Tecumseh compressors have 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 Sanden-style rotary compressor.
Converting to 134a? You get everything needed to convert to 134a except the refrigerant itself. Highly efficient direct replacement parallel flow condenser, along with a rotary compressor will help with system efficiency that is lost when converting your system from R12 to 134a. (More information is available for converting to 134a. Click on the 134a Info above)
Save Horsepower. Our rotary compressor draws significantly less horsepower of stock compressor; approximately 2-4 horsepower compared with 5-10 horsepower from stock.
Increase Fuel Economy. Less horsepower draw means better gas-mileage.
Save Weight. The rotary compressor is about half the weight of stock compressor/clutch assembly.
Running engine at high RPM? The compressor can handle 6,000 continuous RPM!
WHAT DO I GET WITH THIS KIT?
Sanden-style rotary compressor & clutch assembly.
Compressor Mount Adapter bracket - Designed to allow the new compressor to sit on the original factory A/C Compressor Mount.
High-performance "Parallel Flow" Condenser that installs as original.
New replacement Liquid Line & Hose set (This replacement set does away with the original style sightglass & quick disconnect fittings, which eliminates possible leak points between the line and hose connection).
New Suction Hose with 134a Charge Port (from compressor to to accumulator), including specialized model-specific evaporator fitting*
New Discharge Hose with 134a Charge Port (from compressor to top fitting on condenser), including specialized model-specific condenser fitting*
*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.
New replacement Filter/Drier
O-Rings & oil tube
All the tech support you need!
WHAT ENGINES DO THE COMPRESSOR BRACKETS FIT?
Any stock 302/351/360/390/400/460 engine with the original compressor mount, idler and idler bracket.

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.
Other than crimping one end of the hoses and charging the system, no other specialized tools or knowledge is required for installation of parts.
CONVERTING MY FORD 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.
Systems w/o Suction Valve Minimum Requirements
Systems w/POA Valve (aka Suction Throttling Valve & By-Pass Valve) The POA Valve is installed on the evaporator, near the firewall. (Click here for a typical photo)
Systems w/Accumulator The accumulator is most often installed on the evaporator, near the firewall, but occasionally found in the middle of the suction hose between the evaporator and the compressor. (Click here for a typical photo)
