Gates EHV117 HVAC Heater Control Valve

Electric Heater Control Valve for Ram HVAC

The Gates EHV117 electric heater control valve regulates coolant flow through the heater core to help maintain the requested cabin temperature. It is built for vehicles that use electric coolant valves for thermal management, including applications that manage heat for the passenger compartment and, in electrified systems, battery temperature control.

Compatible With select Ram 1500, Ram 1500 Classic, Ram 2500, and Ram 3500 applications, this valve is an OE Exact replacement with the same 20 mm inlet and outlet port sizing and a male electrical connector.

Key Features

• Gates Electric Heater Control Valve, part number EHV117
• OE Exact comparison rating for direct replacement use
• 2 inlet ports and 1 outlet port
• 20 mm inlet and outlet outside diameter
• Male terminal and male electrical connector type
• Plastic/metal construction for HVAC coolant control service
• Contents: coolant control valve and heater control valve

Product Details

The Gates EHV117 is an electric coolant valve used in HVAC temperature control systems to meter coolant flow through the heater core. In modern Ram truck applications, this type of valve helps the system respond to cabin heat demands by opening or closing coolant passage as commanded by the vehicle’s control strategy. Gates positions the Electric Heater Control Valve line for vehicles that rely on electric coolant management, including internal combustion and electrified platforms.

This part cross-references Mopar 52014892AB and 52014892AC for the same application. If you are replacing a failed heater control valve on a Ram 1500, Ram 1500 Classic, Ram 2500, or Ram 3500, EHV117 provides the correct port layout and connector style for the listed vehicles.

What It Helps Fix

• Inconsistent cabin heat output
• Heater core coolant flow that does not respond correctly
• Temperature control that stays too hot or too cold
• Coolant valve electrical faults tied to HVAC operation
• Thermal management issues in vehicles using electric coolant valves

Installation Notes

Verify the inlet and outlet port diameters, connector style, and OE part number before installation. Inspect the surrounding coolant hoses, electrical connector, and sealing surfaces for wear or contamination before installing the new valve. After installation, refill and bleed the cooling system according to the vehicle service procedure to remove trapped air and confirm proper heater operation.

Quality Assurance

Gates manufactures the EHV117 as an OE Exact replacement part for the specified Ram applications. The Electric Heater Control Valve product line is engineered for modern coolant control systems used to manage passenger compartment heating and, where equipped, broader thermal management functions.
