The Gates electric heater control valve for 2011–2015 Chevrolet Volt applications is a coolant control valve specified for the Volt's electric heater system. Provided for these model years, the valve routes coolant under electrical control to support battery or HVAC thermal management as described, helping restore proper heating and coolant routing when the original valve fails.
