a restriction somewhere in the cooling system maybe the fan
No, a clogged heater core will not make it overheat. A leaking heater core will.
To make sure the water heater is always supplied and don't run dry, which could cause it to overheat.
o speed up the particles of the silver fork you could hang onto it (your body temperature is higher than the temperature of the fork) so you will cause the warmer particle movement from your hand to heat up the fork.
The antifreeze level could be low, or the thermostat may need to be replaced, or the antifreeze line might need to be blead to get all the air out, the air in the line will make it overheat.
First check the truck for coolant leaks, make sure the coolant level is o.k. If it is there could be a blockage in the radiator or hoses if you have no idea what you are doing take it to an automotive repair facility an overheat could cause severe engine damage
no but if you try to run the car with the water pump out you could overheat your engine
The thermistat could be bad, check to make sure the fan is kicking on.
No, not an alternator itself. A slipping belt driving the alternator and the water pump could though.
Yes, it could even make it completely ineffective. If it is in a car it can ruin gaskets, seals, or make your car overheat. Which can warp your the pistons in you car.
drive it without coolant
yes
Try replacing radiator cap Is cooling fan working? Make sure radiator is not plugged or dirty Check coolant level water pump
