What It Helps Address

• Loss of cabin cooling from a leaking evaporator core
• Reduced A/C performance caused by internal corrosion or blockage
• Uneven vent temperatures in the HVAC system
• Service replacement for damaged or worn evaporator components
• Restoration of proper refrigerant heat exchange in the dash HVAC case

Installation Notes and Tips

Verify the core width, height, and depth against the original unit before installation. Because evaporator replacement typically requires access to the HVAC case, confirm the vehicle’s refrigerant has been properly recovered and the system is clean before reassembly. Use the exact fitment listing for Ram 1500, Ram 2500, Ram 3500, Ram 4000, Ram 700, and Ram 1500 Classic applications.
