What causes a car to get very hot?
A car’s thermostat is what regulates the circulation of coolant through the cars cooling system – it stays in the closed position when the car is cold and opens as it heats up. As the thermostat ages, it can fail and remain closed which will cause your car to get very hot…quickly.
Why does my car AC keep blowing hot air?
The condenser is the part of the AC unit that’s responsible for radiating or dissipating the heat from the liquid refrigerant coming from the compressor. When this component works as expected, it allows the liquid refrigerant to cool down a bit so it can return to a gaseous state again as it flows back through the rest of the unit.
Why does my car’s radiator run so fast?
I’m not a Benz mechanic so what I’m stating is from an experience I had on my 2008 C300. Two things will make your radiator fan run on fast. Either a signal that the engine is hot or that the air conditioning condenser (located in front of the radiator) is telling it that it’s hot and to run fast to cool it down.
What causes a car to overheat while running?
You may have to flush the system to fix the problem. A malfunctioning thermostat might also be a likely reason for overheating while the car is running at a regular speed. This can also be caused by a damaged radiator, faulty radiator cap, lower level of coolant or a trapped air bubble in the system.

Why does my radiator fan run full speed when I start the car?
Immediately upon starting the car, the radiator fan begins to run full speed, even though the car is stone cold. The AC is OFF. The radiator and condenser are BRAND NEW. This problem existed before and after the radiator was replaced. The fan continues to run at its maxiumum speed, regardless of the engine temperature.
You may have to flush the system to fix the problem. A malfunctioning thermostat might also be a likely reason for overheating while the car is running at a regular speed. This can also be caused by a damaged radiator, faulty radiator cap, lower level of coolant or a trapped air bubble in the system.
What to do if your car is overheating when the AC is on?
Taking off the radiator cap can be very dangerous if the engine is overheated due to the AC. Park the car and put it into neutral. Revving the engine can help you to release some of this excess heat, but don’t do it too much in case there is some other damage to the engine.
