Re: heatercore clogged how to
Check your heater control valve on the collant lines going to the heater core. If working right 1 line going into the heater core should be hot and the sec should be WARM not cold.
I the line comming out of the heater core is cold then its pluged.
Replace it dont use any heavy chemicals because you will NEVER get all that junk out of the coolant system and the chemicals could cause you move problems like water pump and head gasket problems
