1966 Pontiac Grand Prix Compressor Upgrade Kit Includes

• Modern, rotary compressor
• Compressor mount brackets
• Suction and Discharge Compressor hoses (Supplied with one end open on each, along with appropriate fittings. 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
• Filter-drier
• Technically correct 180 degree fitting for evaporator so you can connect it to the support bracket just like your factory air conditioning hose

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

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 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'll need to recalibrate (recondition or rebuild depending on condition) your POA valve. The POA valve is a type of suction valve generally used on 1966 - 1974 GM vehicles to regulate air conditioning system pressure. It is mounted on the evaporator's top (suction) outlet.
