A thermostat opens to allow coolant flow when what component of the thermostat has expanded?

The wax or gas element inside the thermostat expands in response to the increasing engine temperature, causing the thermostat to open and allow coolant flow to regulate the engine temperature.


What causes the thermostat to open?

The thermostat opens in response to the engine reaching a certain temperature. It is designed to regulate the flow of coolant through the engine to maintain optimal operating temperature.


What happens when thermostat fail?

When a thermostat fails, it may not regulate the temperature correctly, leading to the heating or cooling system running non-stop or not at all. This can result in uncomfortable temperatures, higher energy bills, and potential damage to the heating or cooling system. It is important to have a faulty thermostat repaired or replaced promptly to maintain a comfortable and efficient indoor environment.


What happens to the mercury in a thermostat that results in the heater turning on?

When the temperature drops, the mercury in the thermostat contracts, causing it to tilt and complete an electrical circuit that turns on the heater. This circuit allows electricity to flow through the heating system, activating it and raising the temperature in the room.


What is a thermostat jiggle pin?

The Jiggle pin allowes any trapped air behind the thermostat to pass through. Without this the engine could overheat. The thermostat uses engin coolant to melt a wax capsule and allow coolant to pass. The engin could be at operating temp and the thermostat would not open due to air being in contact with the capsule instead of the actual coolent. This would most likely lead to an overheating engin, and damage.

Can an automobile thermostat stick open?

Yes they can stick open or closed. An automobile thermostat is just as likely to stick open as it is to stick shut. Symptoms of a stuck open thermostat are slow to reach normal operating temperature and only warm air blowing from the heater. Symptoms of a stuck closed thermostat are engine over-heating and radiator boil-over.
