1975 Pontiac Grand Prix Compressor Upgrade Kit Includes

• Modern, rotary compressor
• Compressor mount brackets
• Suction (from Compressor to VIR) and Discharge (from Compressor to top fitting on Condenser) Compressor hoses (Supplied with one end open on each, along with appropriate ends or hose openings. Trim to fit and either clamp or crimp new fittings on locally or send to us and we'll crimp and return them for free)
• O-rings
• Hardware
• VIR Rebuild Kit w dessicant bag (If converting to 134a Refrigerant, consider our VIR Eliminator Kit)
• All the tech support you need

Essentially everything air conditioning related in the engine compartment except for evaporator, liquid hoses, pulleys, condenser, safety switch, and VIR.

The factory system did not have a safety switch, relying instead on a discharge outlet on the stock A6 compressor. The compressor included with this kit does not have a discharge outlet and so we strongly recommend adding a 1975 Safety Switch.

We recommend that as part of your air conditioning system repair, you convert to a 134a refrigerant system although that is not required. If you do convert to 134a, we recommend our VIR Eliminator Kit.

The VIR (Valves-in-Receiver) combines the Expansion Valve, POA Valve and accumulator (which substitutes for the Filter-Drier) in one valve. On the 1975 Pontiac Grand Prix’s, the VIR is mounted to the Evaporator unit on the passenger side firewall.

While the VIR systems function well with the old R12 refrigerant they were designed for, the inability to adjust their calibration makes them marginal at best for use with 134a refrigerant. Our VIR Eliminator Kit replaces the VIR with the Accumulator equipped cycling-clutch-orifice-tube (CCOT) used on modern GM vehicles.

Excellent attention to detail makes for a very attractive under-hood appearance and an easy installation on your 1975 Pontiac Grand Prix. Call or email us to find out how to upgrade your 1975 Pontiac Grand Prix.

Note: Our 1975 Pontiac Grand Prix Compressor Upgrade Kit was engineered for stock, factory air applications. If the engine or air conditioning of your 1975 Pontiac Grand Prix has been modified, we'll need to talk to you about a custom solution. Call or email us.

This Compressor Upgrade Kit also works for the Late 1973 Pontiac Grand Prix, the 1974 Pontiac Grand Prix, and the 1976 Pontiac Grand Prix.

1975 Grand Prix Condenser

The Condenser on a factory air 1975 Pontiac Grand Prix is the radiator-like device mounted in front of the radiator in the engine compartment.

The factory air Condenser in a 1975 Pontiac Grand Prix was a tube and fin Condenser.

We offer reconditioning services for your original 1975 Pontiac Grand Prix Condenser. We can even make a new one using your original as a sample. Give us a call or email and let’s discuss the best options for your situation.

A/C INFO:

Car air conditioning is nothing more than continuous heat transfer by two heat exchangers. One heat exchanger, the Evaporator, absorbs heat from the passenger compartment. The other heat exchanger, the Condenser, dissipates that heat into the outside air. All other things being equal, size matters. A larger Evaporator and a larger Condenser exchange more heat than smaller ones and allow the air conditioning system to cool better.

CONDENSER MAINTENANCE TIP:

Try to keep your Condenser as clean and free of bugs and debris as possible. The Condenser's ability to transfer heat is based on air flow. When the Condenser air flow becomes obstructed, it becomes a less efficient heat exchanger.

On a factory air 1975 Pontiac Grand Prix, the Evaporator housing is located in the engine compartment on the passenger side firewall.

We offer reconditioning and rebuilding services for your original 1975 Pontiac Grand Prix Evaporator. Give us a call or email and let’s discuss your situation.
