1974 - 1976 Pontiac Firebird Air Conditioning A/C VIR Eliminator Upgrade Kit

Our valve in receiver (VIR) eliminator kit is a simple, cost-effective alternative to using R12 or a poorly converted 134a system by updating the system to the newer accumulator clutch cycling system that GM converted to in 1977 and continues to use today.

WHY DO I NEED TO ELIMINATE MY VIR?
Unlike nearly every other General Motors designed systems, VIRs cannot be calibrated differently from the factory setting. As a result, VIR equipped cars cannot be adequately converted to 134a.

WILL I NEED TO MODIFY MY CAR OR PARTS?
You will be splicing the cycling switch harness into the compressor power wire. Assuming all components in the system are functional, simply remove the VIR and install this kit. Unlike some similar kits, this kit will not require modification to the car's original hoses.

ON SOME VEHICLES EQUIPPED WITH ENGINE COMPARTMENT SUPPORT BRACKETS, THE BRACES MAY NEED TO BE MODIFIED OR REMOVED IN ORDER TO CLEAR THE NEWLY INSTALLED ACCUMULATOR.
WILL I NEED TO BUY ANYTHING ELSE?

This 74, 75, and 76 Firebird and Trans Am kit includes everything necessary to delete and replace the VIR, converting the system to a clutch-cycling system. Assuming all components in the system are functional, simply remove the VIR and install this kit.

NOTE: Some 1973 and early 1974 models use a POA Valve instead of a VIR. Please double check your application before ordering.
