Product Details

The Gates Electric Coolant Valve line addresses the growing need for precise coolant routing in both electrified and internal combustion vehicles. In many late-model systems, the valve helps direct coolant through the heater core to control cabin temperature, while in electrified platforms it also supports battery thermal management for efficiency and battery life. This EHV163 valve is an OE Exact replacement for service applications that require the same port sizing, connector style, and material profile as the original component.

This part cross-references 16670F0030 and 16671F2010 for the same application.

What It Helps Solve

• Inconsistent cabin heat output
• Coolant flow control issues in the heater circuit
• Thermal management faults in electrified vehicle systems
• Leaking or sticking electric coolant valve operation
• Fitment problems caused by incorrect port size or connector type

Installation Notes and Tips

• Verify the inlet and outlet port diameter before installation.
• Confirm the female connector style matches the vehicle harness.
• Inspect coolant hoses, clamps, and seals during replacement.
• Bleed the cooling system after service to remove trapped air.
• Use the vehicle-specific service procedure for coolant refill and valve calibration, if required.
