What happens when the thermostat is closed on a radiator?
If the thermostat flap remains closed, no coolant can escape to the radiator. The coolant inside heats up and begins to convert to steam, while the coolant inside the radiator remains unchanged. So if you see the temperature gauge rise and the radiator tank is filled with water, you most likely have a problem with the thermostat.
Can a bad thermostat cause an engine temperature to go up?
If the timing is not correct, the engine temperature will fluctuate, and the temperature gauge will respond abnormally. This can also be caused by an electrical failure or air in the coolant system, but you should never exclude a thermostat failure from the equation.
How does the thermostat affect the cooling system?
Minor thermostat problems can mimic more serious issues with the HVAC system and directly impact cooling system performance and comfort. When thermostat problems develop, they are rarely dramatic events with sparks flying, or where smoke alarms sound.
Is there a problem with my air conditioner thermostat?
Any change in air conditioner performance is worrisome, but before calling a cooling expert, check the thermostat. Minor thermostat problems can mimic more serious issues with the HVAC system and directly impact cooling system performance and comfort.

What causes the radiator on a car to overheat?
14 – A Collapsing Radiator Hose Will Shut Down Your Cooling System. A collapsing radiator hose is usually caused by vacuum and is a sign of cooling system blockage or a bad radiator cap. A collapsing radiator hose will prevent coolant from moving through your cooling system and will quickly cause engine overheating.
What happens to the coolant level in a radiator?
You’ll observe the coolant level drop as the air is cycled out, and see air bubbles escaping from the radiator, and perhaps hear it gurgle. Observe the temperature gauge as this is happening. The gauge should decrease to normal or close to normal.
