Fellow Ford Drivers,
Around November last year the heater on my 1978 Ford Granada stopped working. I replaced the thermostat, put air through the hose leading to the heater core (no blockage and no leaks), the air flow changed as I moved the lever through the settings, and both the lower and upper radiator hoses were hot. In April I noticed a small leak on the radiator and had to replace my
14 year old Modine with a Visteon. The heater now works so my question is how can a radiator prevent the heater from working? Is this unusual?Thanks for any input
