Heater Core Replacement near Lenoir City, Tennessee

This can be a labor-intensive repair, as the dashboard must be removed from the vehicle in most cases to access the heater core. Once engine coolant lines are removed and the heater core is accessed, the new heater core will be installed. After everything is put back together, the heater core is connected to the hoses, and the engine coolant is topped off and bled of air.

Sticking to the car's maintenance schedule is the best way to prevent heater core problems. The engine coolant used in the vehicle should be the type recommended by the manufacturer. Quality replacement heater cores have excellent anticorrosive protectants applied inside and outside, and should not need another replacement if the cooling system is maintained.

Because of the amount of disassembly required, and the fact that airbags often have to be removed, this job is best left to a professional.
