'01 F150 XL 4.2 ----heater core test
Only cold air inside cab with temp selector on Hot.
Ran engine till temp was hot.....felt both heater core hoses and were barely warm/cool.
Disconnected both heater core hoses from engine.....pressured inlet with water hose ....not much water coming out of outlet??
Appears clogged?
Can i flush out core?
