Gates EHV126 HVAC Heater Control Valve

Gates EHV126 Electric Heater Control Valve

The Gates EHV126 is an OE Exact electric heater control valve built to regulate coolant flow through the heater core and support thermal management in modern vehicles. It is a direct-fit solution for select Ford and Lincoln applications, including Expedition, Navigator, and F-150 models.

Gates Electric Heater Control Valve products are engineered for vehicles that rely on electric coolant control for passenger cabin temperature management and, in electrified platforms, broader thermal control functions. The EHV126 follows the same OE-style layout and connection points used in the original system.

Key Features

• OE Exact comparison rating for direct replacement fit
• Electric coolant control valve for heater core flow regulation
• Plastic/steel construction for underhood durability
• Male electrical connector type
• 1 inlet and 1 outlet with 0.75 in. / 19 mm outside diameter
• Contents: coolant control valve

Detailed Description

This Gates EHV126 heater control valve is used to manage coolant flow through the HVAC heater circuit, helping the system deliver the requested cabin temperature. It is designed for vehicles that use electric coolant valves as part of their thermal management strategy, including applications where precise coolant routing supports both comfort and efficiency. Compatible With 2018-2021 Ford Expedition, 2018-2021 Lincoln Navigator, and 2018-2020 Ford F-150 heater control valve applications, this part number is a direct OE-style replacement for the original component. This part cross-references Ford service numbers JL3Z 18495 A and JL3Z 18495 E for the same application.

What It Helps Solve

• Inconsistent cabin heat output
• Coolant flow not switching properly through the heater core
• Temperature control that does not respond correctly to HVAC commands
• Faults related to an electric heater control valve in the cooling circuit
• Replacement needs after valve wear, sticking, or electrical failure

Installation Notes and Tips

Verify inlet and outlet size, connector style, and vehicle application before installation. The EHV126 uses a male electrical connector and 19 mm (0.75 in.) inlet and outlet dimensions, so matching the original valve configuration is important for proper fitment. Confirm the vehicle’s HVAC or cooling system diagnosis before replacing the valve, and inspect surrounding coolant hoses and connectors for wear or contamination during service.

Quality Assurance

Gates manufactures the EHV126 as an OE Exact replacement part for select Ford and Lincoln heater control valve applications. The design reflects the original equipment style used in modern thermal management systems, including electric coolant flow control for passenger compartment heating.
