Product Details

The Gates Electric Heater Control Valve line addresses modern thermal management needs in both electrified and internal combustion vehicles. In applications such as the Dodge Sprinter 2500, Dodge Sprinter 3500, Mercedes-Benz Sprinter, and Mercedes-Benz SL600, this valve regulates coolant flow to the heater core so the passenger compartment can reach and maintain the selected temperature. The EHV118 is also used in systems where electric coolant valves support broader vehicle thermal control functions. This part cross-references 5103770AA and 0018300684 for the same application.

Common Issues This Part May Address
