Different Types of Car Thermostat Function

A car's engine generates a tremendous amount of heat as it operates. This heat must be regulated to keep the engine at a temperature that is optimal for its operation. The electric thermostat for car is one of the key components in a car's cooling system that helps to regulate engine temperature.


In this article, we will explore the different types of thermostats used in cars and their functions, including Wax Thermostat, Thermostat Housing, Map-Controlled Thermostat, and Heavy Duty Thermostats.


Wax Thermostat Function:


Wax thermostat is commonly used in cars and trucks. They are made up of a wax element that expands and contracts as it heats up and cools down. When the engine is cold, the wax element contracts, allowing coolant to flow freely through the engine. As the engine warms up, the wax expands, blocking the flow of coolant until the engine reaches its optimal temperature.


Wax thermostats are simple and reliable, but they do have a few drawbacks. They can be slow to react to changes in temperature, and they can also become stuck in the open or closed position, causing engine overheating or poor performance.


Thermostat Housing Function:


The thermostat housing is the component that encloses the thermostat and attaches it to the engine. The integrated thermostat housing is typically made of metal and is located on the engine block. It also contains a gasket that seals the housing to the engine and prevents coolant leaks.


In addition to holding the thermostat in place, the housing also directs the flow of coolant to and from the engine. The thermostat housing can also have a temperature sensor attached to it, which sends information to the car's computer to regulate engine performance.


Map-Controlled Thermostat Function:


Map-controlled thermostat is a newer technology that is becoming more common in modern cars. Instead of using a wax element, map-controlled thermostats use an electric motor to open and close a valve that regulates coolant flow to the engine.


These thermostats are controlled by the car's computer and can adjust the engine's temperature based on factors such as driving conditions, engine load, and ambient temperature. This allows for more precise temperature regulation and better engine performance.


Heavy Duty Thermostat Function:


The heavy-duty thermostat is designed for use in high-performance or heavy-duty vehicles, such as trucks or race cars. These thermostats are typically made of stronger materials, such as stainless steel, and are designed to withstand higher temperatures and pressures than standard thermostats.


Heavy-duty thermostats can also have larger valve openings, allowing for increased coolant flow to the engine. This can help to prevent overheating and improve engine performance.


Maintain Car Cooling System


In addition to these different types of the electronic automotive thermostat, there are also a few key things to keep in mind when it comes to maintaining your car's cooling system.


First, it's important to check your coolant levels regularly and top them off as needed. Coolant helps to regulate engine temperature and prevent overheating, so it's essential to keep it at the right level.


Second, it's important to have your cooling system inspected and serviced regularly. This includes checking the thermostat, radiator, hoses, and other components to ensure that they are all in good working condition.


Finally, it's important to address any overheating issues as soon as they arise. Overheating can cause serious damage to your engine and other components, so it's important to take action quickly to prevent further damage.


In conclusion, the thermostat is a critical component in a car's cooling system that helps to regulate engine temperature and prevent overheating. Whether you have a traditional wax thermostat or a modern map-controlled thermostat, it's important to maintain your cooling system and address any issues promptly to keep your engine running smoothly.
