Description

In trucks with the AC on, hot engine coolant flows through the heater core, even when air is diverted. This valve automatically shuts off coolant flow to the heater core when the MAX AC setting is selected, resulting in a noticeable decrease in duct temperature. Installation is straightforward, taking approximately 15 minutes with no special tools required, and the kit includes all necessary components and detailed instructions.
