• Fogging caused by heater core leakage
• Restricted coolant flow through the HVAC heater circuit

Installation Notes and Tips

Confirm vehicle fitment by year and model before installation. Adjustable pipe positioning is not included, so the heater hose connections must align with the factory routing. Because heater core replacement often requires access through the HVAC case, inspect related coolant hoses, clamps, and seals during service. Proper coolant refill and system bleeding are important after installation to restore normal heater performance.
