If the coolant levels are ok, check to see if the fan spins, and see if there's a blockage in the radiator hose
No
Mazda used the ford ranger body but used the Mazda engine.
Not necessarily. It depends on what you mean by a bad heater core. The core will either be leaking or stopped up. If it is leaking, then it can cause the engine to overheat and the only fix is to replace it. A clogged or plugged heater core can sometimes be fixed by flushing it. You can also temporarily bypass the heater core until you can get it fixed. Just connect the inlet & outlet heater hoses together.
