Heater Control Valve for 1987-1995 Chevrolet Camaro & More - Four Seasons 74805

Keep cabin heat under control with the Four Seasons heater control valve, part number 74805 — a vacuum-operated valve that regulates the flow of engine coolant to the heater core. It's an application-specific, direct-fit replacement for many vehicles, including the 1987-1995 Chevrolet Camaro, 1989-1996 Chevrolet Caprice and 1991-1994 Chevrolet Commercial Chassis.

• Vacuum controlled: operates off engine vacuum to open and route coolant to the heater core.
• Non-bypass design: non-bypass style valve with three connectors.
• Temperature tested to 270°F and pressure tested for a leak-free design.
• Plastic construction with an application-specific design engineered for years of trouble-free operation.

The heater control valve meters how much hot engine coolant reaches the heater core, controlling the heat delivered to the cabin. When the valve sticks or leaks, you may notice heat that won't shut off, weak or no heat, or coolant seepage — if a failed valve is the cause, this replaces it. Backed by over 50 years of mobile A/C experience from Four Seasons.
