System which removes excess heat from liquid cooled internal combustion engine. It also helps maintain the engine temperature at a consistent level. The cooling system encompasses the radiator, water pump, thermostat, hoses, heater core, overflow reservoir, and anti-freeze (or coolant).
How does the heater core work? What are the inputs to the system? What are the outputs of the system? What are some common ways that it can fail?
2003 ford exp xlt overheating. replaced t-stat and dumped & refilled coolant. Still over heating bad when on the highway at about 65 mph.
