Product Details

Gates EHV149 is part of the Electric Coolant Valve line, a product line focused on electronically controlled coolant routing for modern thermal management systems. In vehicles such as the Chrysler Pacifica and Chrysler Voyager, this valve helps direct coolant through the heater core so the cabin temperature setting can be controlled accurately. In electrified platforms, similar valves are also used to manage battery temperature as part of the overall cooling and heating strategy.

This part cross-references Dorman - HELP 74931 for the same application. The Gates EHV149 is also referenced by OE numbers 68237835AA, 68237835AB, and 64129153079.

Common Issues This Part May Address

• Inconsistent cabin heat output
• Heater temperature that does not respond correctly to control changes
• Restricted or uneven coolant flow through the heater core
• Thermal management faults related to electric coolant valve operation
• Cooling or heating control concerns in vehicles with electronically managed coolant circuits

Installation Notes and Tips

Verify connector style, port size, and OE reference numbers before installation. Confirm the valve location in the HVAC or thermal management circuit on the Chrysler Pacifica or Chrysler Voyager, and inspect the surrounding coolant hoses and electrical connector for wear, corrosion, or contamination before reassembly.

Quality Assurance

Gates manufactures this valve to OE Exact standards for application-specific fit and function. The EHV149 is built to match the requirements of modern electric coolant valve systems used in HVAC and thermal management circuits.
