Gates EHV144 HVAC Heater Control Valve

Gates Electric Coolant Valve EHV144

The Gates Electric Coolant Valve EHV144 is an OE Performance HVAC heater control valve built for precise coolant flow management in modern thermal systems. It is used on Tesla applications where electric coolant routing helps regulate passenger cabin heat and, on electrified platforms, battery temperature control.

Key Features

• Plastic valve body for lightweight, OE-style construction
• 19 mm inlet port outside diameter
• 19 mm outlet port outside diameter
• Female connector design
• 2-port configuration for controlled coolant routing
• OE Performance grade for direct replacement service
• Brand line: Gates Electric Coolant Valve for thermal management applications

Product Details

Gates EHV144 is an electric coolant valve engineered for HVAC temperature control and thermal management in Tesla vehicles. In Tesla S and Tesla X applications, this valve helps regulate coolant flow through the heater core to manage cabin temperature, while also supporting electric vehicle thermal systems that balance battery heating and cooling. The Gates EHV144 is a direct-fit service part for 2021 Tesla S, 2012-2020 Tesla S, and 2016-2021 Tesla X applications listed in the fitment data.

This part cross-references 600737000B and 600737050E for the same application. Search terms such as Tesla S electric coolant valve replacement, Tesla X heater control valve, and Gates EHV144 coolant valve are commonly used when sourcing this component.

What It Helps Address

• Inconsistent cabin heat from restricted coolant flow
• HVAC temperature control issues in Tesla S and Tesla X models
• Electric coolant routing concerns in thermal management systems
• Heater core flow control problems affecting passenger compartment temperature
• Battery thermal regulation service needs on electrified vehicle platforms

Installation Notes and Tips

Verify the inlet and outlet port size, connector style, and vehicle application before installation. Confirm the valve orientation and coolant line routing against the original part on the vehicle. After replacement, refill and bleed the cooling system according to factory service procedures to remove trapped air and restore proper flow.

Quality Assurance

Gates manufactures OE Performance replacement components for thermal management and HVAC service applications. EHV144 is built to match the functional requirements of the original electric coolant valve used in the listed Tesla fitments.
