If the chirping noise speeds up as the truck speeds up, check the u-joints in the drive line.
Bad mount on the steers, worn/loose/damaged steering components, axles out of alignment.
Check to make sure the fan clutch is engaging.
Too high a temperature
it is possible for heat from combustion to cause an engine to overheat quickly depending on where the gasket is blown, but i would look for a lack of coolant circulation first. if your coolant is not getting out of the motor and into the radiator it will overheat very quickly.
Brakes, wheel bearing.
A stuck or incorrectly installed thermostat.
It will not cause the engine to overheat. You have another problem.
The heater will stop getting hot when you're low on coolant. If the coolant is low enough the engine will overheat and it will be severely damaged.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
The radiator cooling fan is most likely not working.
Yes it could.
