Product Details

The Four Seasons Heater Valve line focuses on replacement HVAC temperature-control components for vehicles that use vacuum-actuated coolant routing. Part number 74691 is a non-bypass heater control valve that closes under vacuum, helping regulate heater core flow in the factory-style manner used on many older GM platforms. It is listed as an OE replacement and is built with a steel housing for service in the engine bay.

This part cross-references TYC 30301 and UAC HV1002C for the same application. Common fitment includes 1980-1985 Chevrolet Impala, 1980-1990 Chevrolet Caprice, 1982-1990 Buick LeSabre, 1980-1984 Oldsmobile 98, and 1980-1985 Oldsmobile Delta 88. It also appears in searches for 1980s Buick Regal, Oldsmobile Cutlass, and Pontiac Bonneville heater valve replacement.

What It Helps Address

  • Heater output stuck on or stuck off due to a failed vacuum valve
  • Coolant flow not switching correctly through the heater core
  • Loss of cabin heat control in vacuum-operated HVAC systems
  • Leaking or corroded heater control valve housing
  • Incorrect heater valve operation on OE-style GM HVAC setups

Installation Notes

Verify hose connector size and valve orientation before installation. This valve uses vacuum operation and a non-bypass layout, so confirm the vehicle’s HVAC system is not equipped with Electronic Climate Control (ECC) where exclusions are noted. Fitment notes also call out specific applications such as 2-port vertical water outlet, horizontal water outlet, 90-degree hose routing, and threaded right-angle hose connections on certain vehicles.

Fits 1980-1990 Chevrolet Caprice, N/A; fits 1980-1985 Chevrolet Impala, N/A; fits 1982-1990 Buick LeSabre, N/A; fits 1980-1984 Oldsmobile 98, N/A; fits 1980-1985 Oldsmobile Delta 88, N/A.

Quality Assurance

Four Seasons supplies HVAC replacement components for temperature-control service, and this heater valve is built as an OE replacement part for the listed applications. Part number 74691 is intended for direct replacement use where the original system calls for a vacuum-closing non-bypass heater valve.
