Over the past two years I have forward/reverse flushed my heater core
and have seen improvement in my cabin heat. The only problem is that I
have to forward/reverse flush my heater core every couple of months.
Do I need a new heater core? Does it need to be professionally
Recently I noticed the car was losing coolant and found the leak at the
plastic radiator neck. Could the leak in the radiator have caused the
poor flow through the heater core?
Any ideas or similar experiences?
