Installation Notes

Confirm vehicle fitment by year, make, and model before installation. Because heater core replacement often requires access through the HVAC case, inspect related hoses, seals, and coolant condition during service. Adjustable pipe positioning is not included on this part, so verify the original pipe orientation against the replacement before assembly. Use the vehicle service procedure for coolant draining, system refill, and air bleeding after installation.
