What is the function of thermostat in engine cooling system?

The thermostat is like a valve that opens and closes as a function of its temperature. The thermostat isolates the engine from the radiator until it has reached a certain minimum temperature. Without a thermostat, the engine would always lose heat to the radiator and take longer to warm up.

What is the engine cooling thermostat?

What Does a Thermostat Do? Your car’s thermostat is a vital component that is actually pretty simple. It’s a valve located in your car’s cooling system. Its job is to regulate the amount of coolant that is recirculated back into the engine and how much is cooled via the radiator prior to being recirculated.

What are the functions of the thermostat?

Functions of Thermostat

The primary function of a thermostat is to control the working temperature of the engine.
With the component, the engine is prevented from overheating and excess cooling.
At cold start, thermostat blocks the coolant to flow.
Also, it ensures coolant absorbs heat before entering the radiator.

How does a cooling system thermostat work?

An engine cooling system thermostat is designed to stop the flow of coolant in the cooling system when the engine is cold, this is done to help the engine warm up to optimum operating temperature which improves efficiency and emissions output. Once the engine heats to 195° F or 96° C it will open allowing…

Where does coolant go when the thermostat is opened?

Coolant will remain inside the engine block until the engine reaches a predetermined temperature that opens the thermostat. This allows hot coolant to flow through the radiator for cooling and cycled back through the engine block.

How big is the thermostat on a liquid cooled car?

Any liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. The thermostat in most cars is about 2 inches (5 cm) in diameter.

Why is the thermostat important in a BMW?

The cooling system on any BMW is critical to maintaining performance and longevity of your engine. Poor cooling maintenance will result in overheating and potentially do permanent damage to your vehicle. The thermostat is a critical part of engine cooling system.

What makes up the cooling system of an engine?

The cooling system is composed of six main parts—an engine, a radiator, a water pump, a cooling fan, hoses, and a thermostat. During the combustion process, some of the fuel energy is converted into heat. This heat is transferred to the coolant being circulated through the engine by the water pump.
