What It Helps Resolve

• Weak or uneven cabin heat
• Coolant odor inside the vehicle
• Fogging or film on the inside of the windshield from heater core leakage
• Loss of heater performance caused by restricted coolant flow through the core
• Coolant seepage at the HVAC heater core assembly

Installation Notes and Tips

Verify inlet size, core dimensions, and hose routing before installation. Because the pipe position is not adjustable, alignment should be checked against the original unit before reassembly. Flush the cooling system and inspect related hoses, clamps, and the thermostat housing or water outlets if contamination or restricted flow is present.
