- Temperature inconsistency during cold-weather driving
Installation Notes and Tips
Verify vehicle fitment by year and model before installation. The heater core is located within the HVAC case, so access typically requires disassembly of interior heating and air conditioning components. Inspect coolant condition, hoses, and seals during replacement, and flush the cooling system if contamination is present. Confirm the included pipes match the original configuration on the vehicle before assembly.
