Product Details

Gates Electric Coolant Valve EHV147 is engineered as a heater control valve for vehicles that use electric coolant flow management to control passenger compartment temperature. In Mercedes-Benz SL500, SL320, 300SL, 300TE, 300CE, and 300E applications, this valve helps direct coolant through the heater core so the HVAC system can respond correctly to temperature settings. The Gates Electric Coolant Valve line focuses on thermal management components used to control coolant routing in modern vehicle systems, and EHV147 follows that OE-style approach for service replacement.

This part cross-references Mercedes-Benz 0008307284 for the same application.

Common Symptoms Addressed

• Inconsistent cabin heat output
• Heater stuck on hot or cold
• Coolant flow control issues in the HVAC circuit
• Faulty electric valve operation affecting temperature regulation
• Leakage or wear at the heater control valve assembly

Installation Notes

Verify port size, connector style, and mounting location before installation. This valve uses an 18 mm inlet and outlet port outside diameter with a male connector, so matching the original configuration is important for proper fitment. Confirm the vehicle’s HVAC coolant routing and inspect related hoses, seals, and electrical connections during replacement.

Quality Assurance

Gates manufactures thermal management components for OE-style service replacement, and this valve is built to OE Exact specifications for the listed Mercedes-Benz applications. Compatible With 1990-2002 Mercedes-Benz models including SL500, SL320, 300SL, 300TE, 300CE, and 300E.
