Product Details

Gates EHV122 is part of the Electric Heater Control Valve product line, built for vehicles that use electronically controlled coolant routing to manage heater core flow and, in electrified systems, broader thermal control needs. On the Mercedes-Benz C250 and Mercedes-Benz SLK250, this valve helps regulate coolant movement through the HVAC system so the cabin temperature setting can be controlled accurately. The EHV122 part number is also referenced as 2712030164 for the same application.

What It Helps Address

• Inconsistent cabin heat output
• Heater core coolant flow control issues
• Temperature setting response problems in the HVAC system
• Coolant routing faults related to electric valve operation
• Thermal management concerns in select Mercedes-Benz C250 and SLK250 models

Installation Notes

Verify inlet port sizes, connector style, and OE comparison rating before installation. This valve uses a female electrical connector and two inlet ports, so matching the original configuration is important for proper fitment on 2012-2015 Mercedes-Benz C250 and 2012-2015 Mercedes-Benz SLK250. Follow the vehicle service procedure for coolant system service and electrical connection checks.
