Air Conditioning VIR Eliminator Kit

The 1973 Pontiac Grand Prix came in two versions in terms of factory air conditioning. Production began with a Filter-Drier/Expansion/POA Valve system but later models used a Valves-in Receiver (VIR) system.
The VIR combines the Expansion Valve, POA Valve and accumulator (which substitutes for the Filter-Drier) in one valve. On the 1973 VIR 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. The kit includes:
- A new Accumulator
- Cycling Switch
- Orifice Valve, and
- Fittings.
Simply install the Accumulator and Orifice Valve in place of the VIR, replace one end of your Suction Hose, and wire in the Cycling Switch.
This kit can also be ordered as part of our Engine Compartment Upgrade Kits, replacing the VIR Rebuild Kit. Call or email us.
