Four Seasons 74918 Heater Valve Overview

The Four Seasons 74918 is a single solenoid electronic heater valve built as an OE replacement for HVAC temperature control service. It is used in rear auxiliary heater applications on select Dodge Sprinter vans, where precise coolant flow control is needed for cabin heat management.

Compatible with 2003-2006 Dodge Sprinter 2500 and 2003-2006 Dodge Sprinter 3500, this heater valve supports rear auxiliary heater systems and matches the original equipment application.
