Detailed Description

Gates Electric Heater Control Valve EHV101 is engineered for vehicles that use electric coolant valves to manage heater core flow and broader thermal control functions. In BMW applications, it supports cabin temperature regulation by controlling coolant routing through the heater circuit. This part cross-references Four Seasons 74894 for the same application. Compatible BMW applications include 1992-1995 BMW 325i, 1992-1995 BMW 325is, 1992-1998 BMW 318i, 1992-1998 BMW 318is, 1995-1999 BMW 318ti, 1995-1999 BMW M3, 1996-1998 BMW 328i, 1996-1998 BMW 328is, 1998-1999 BMW 323is, and 1999 BMW 323i, 328i, and 328is with E36 chassis notes where listed.

What It Helps Solve

• Inconsistent cabin heat output
• Heater core coolant flow control issues
• Faulty electric coolant valve operation
• Temperature setting response problems in the passenger compartment
• Thermal management faults related to valve wear or electrical failure

Installation Notes and Tips

Verify inlet and outlet sizing, connector style, and vehicle-specific fitment before installation. Confirm the BMW application and any chassis notes listed for your model year, especially on E36 chassis vehicles. Inspect coolant hoses, electrical terminals, and surrounding HVAC components during replacement to help ensure proper system operation.

Quality Assurance

Gates manufactures the EHV101 as an OE Exact heater control valve for direct replacement service in supported BMW applications and other listed thermal management systems.
