Front

1. Remove the front heater core from the front heater unit.
2. Check for cracks, damage, and coolant leakage. If any are found, replace the front heater core.
3. Check for bent fins. If any are bent, use a flathead screwdriver to straighten them.
4. Verify that the front heater core inlet and outlet are not distorted or damaged. Repair by using pliers if necessary.
