Detailed Description

Gates EHV104 is an electric heater control valve engineered for vehicles that use electronically managed coolant flow to control cabin temperature. In the HVAC system, the valve regulates coolant movement through the heater core so the passenger compartment can receive the requested heat output. In electrified vehicle thermal systems, electric coolant valves also support battery heating and cooling functions to help maintain operating efficiency and battery life.

This part number EHV104 is listed for 2003-2008 Jaguar S-Type, 2003-2006 Lincoln LS, and 2003-2005 Ford Thunderbird. It cross-references Four Seasons 74010 for the same application. The Gates EHV104 uses a 1-inlet, 2-outlet layout with 0.75-inch inlet and 0.625-inch outlets, making it a focused OE-style service part for the original coolant control setup.

What It Helps Address

• Inconsistent cabin heat from restricted coolant flow
• Heater output that stays too hot or too cold
• Faults related to an electric heater control valve circuit
• Coolant routing issues in the HVAC temperature control system
• Thermal management concerns in vehicles using electric coolant valves

Installation Notes and Tips

Verify connector style, inlet and outlet diameters, and OE comparison before installation. Confirm the vehicle uses the listed electric heater control valve configuration and inspect adjacent coolant hoses, clamps, and electrical terminals for wear or corrosion. After installation, refill and bleed the cooling system according to the vehicle service procedure to remove trapped air and restore proper heater performance.

Quality Assurance

Gates manufactures this heater control valve as an OE Exact replacement-style component for the listed applications. The EHV104 is built to match original fitment requirements for service on Ford Thunderbird, Lincoln LS, and Jaguar S-Type HVAC systems.
