Installation Notes and Tips

Verify the vehicle’s year and model before installation. This heater core is listed as a specific fit with no adjustable pipe positioning, so port alignment should be checked against the original unit before reassembly. Because heater core replacement often requires access to HVAC components, inspect coolant condition, hoses, and related seals during service. Fits 2010-2024 Toyota 4Runner, N/A.
