Yes, a broken AC compressor can contribute to a car overheating. When the compressor fails, it can place additional strain on the engine, particularly if the drive belt is affected. Moreover, if the cooling system is not functioning properly due to a malfunctioning compressor, it can lead to insufficient cooling of the engine, resulting in overheating. Regular maintenance and prompt repairs are essential to prevent these issues.
It most certainly could. Most new cars use a single belt to run the "accessories" like the alternator, AC compressor, power steering and...the water pump. With no belt, no coolant is flowing through the engine and into the radiator and the car will quickly overheat.
If it's a creaking noise then it is most likely that your compressor is broken.
drive it without coolant
yes
Try changing the themometer
Yes
Not likely but possible.
No. It actually must remain in the car, because it is on the serpentine belt.
Not unless you loose enough oil to cause a lack of lubrication.
no but if you try to run the car with the water pump out you could overheat your engine
Unplugging an a/c compressor shouldn't effect the heating and cooling system what so ever the only tie it has to that system is the comperessor makes the fan come on when you engage the a/c switch
Not long, combustion gases (hot) generally enter the cooling system and cause the engine to overheat.
