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
I can only guess that coolant level was too low or the heater core had some
sort of temporary blockage..... however, this is NOT November and, if the
heater core is restricted, it will rear it's ugly head once again come cold
For the other responder.... heater cores and radiators fail in one (or both)
of only two ways..... Flow will be restricted through calcification,
sediment or the addition of some popular stop leak products - or..... the
coolant will fall on the ground. If we apply logical thought process, we can
determine that no fluid conduit can fail in such a way that the inside
diameter is larger than the outside diameter without some sort of visible
