Stuck thermostat, clogged radiator, low of coolant, defective water pump, defective cooling fan, blown head gasket, cracked head, just to name the obvious.
There are several common heater problems for a 1997 f150. A stopped up or leaking heater core, bad thermostat or clogged up blower fan housing all can cause heat problems.
if the engine is knocking you could have bad support bushings for the mouter mounts or your engine could be warped do to excessive heat wear
I would definently think that the cause of heat illness would be, I don't know,...HEAT!maybe. I would definently think that the cause of heat illness would be, I don't know,...HEAT!maybe.
The gauge does not cause the heat; it only shows what it is.
Yes, but it would have to be defective already (which, at 12 years old, fits).
I have a 1997 Ford Taurus that would only blow cold air, I replaced the thermostat and no heat. We flushed the system from a ford dealer no heat. Had to replace the heater core plenty of heat now. Other possibilities are: * a malfunctioning temperature blend door * Plugged heater core See "Related Questions" below for more
No , if you were to bypass the heater core , you would have no heat
Not unless your heater core leaks.
a bad water pump could cause low heat. The heater uses the coolant from the pump to generate heat.
Sounds like it is low on coolant.
No.
