Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.

After many hours of testing the cooling system, I tested the heater core for blockage internally, and found the heater core to be almost plugged up. I replaced the heater core and it solved the problem! The heater core was under $100.00, but it took me 15 hours to complete the repair, and I am an SAE certified "Master" mechanic. If you have a repair shop or dealer do the work, it will be expensive.
