The thermostat's role is to control temperature; thus, the engine stays cool. Liquid-cooled engines are affordable, with a thermostat between the engine and the radiator, ensuring the engine cools at an optimal temperature.
How it works
The thermostat checks the temperature as it blocks the flow is of cooling effect to the radiator. Whenever the coolant is cold, the coolant won't flow via the engine. The coolant's water pump pushes its temperature lower from the radiator up to the engine. The thermostat helps in minimizing engine wear, releasing unnecessary emissions and deposits.
Due to the practical design of the thermostat, they are successful. A small cylinder located within the engine's sides suffused with a wax that melts it slowly. The center of the valve is a rod connected that presses the wax to melt; this allows it to expand; thus, the coolant flows the rod out. As the wax expands powerfully, it goes from a solid to a liquid state, ineffective in inflating the heat.
The problem is to tell when the thermostat has a problem, and here is how to tell when the vehicles thermostat is stuck open or closed position:
- Stuck open-when a thermostat is in an open position. A perennial flow of coolant into the radiator compels the engine to run the more emotionless, unluckily no supercooling machines, resulting in increased fuel consumption. Engines with higher emissions increase fuel consumption on engine components.
- Stuck closed-in this position. The coolant is blocked in an entire circulation preventing it from reaching the radiator to be cooled, resulting in sweltering engine temperatures, which causes the vehicle to overheat.
Car Thermostat Trouble Symptoms
Thermostat replacements are not very expensive to repair compared to its cost when replacing an engine; excessive heat and repeated overheating causes damage to the engine.
The three common symptoms that you may experience in your vehicle are:
- The temperature gauge reads high-after a few minutes; when running your engine, you will notice the engine indicating the rise of temperature into the red zone. This leads to a dysfunctional thermostat.
- Temperature changes erratically-as the gauge indicates that the temperature is abnormal due to fluctuations in temperatures leading to poor engine performance.
- Coolant leaks - you can notice the leaks in several locations found in the thermostat housing.
You can see the car thermostat is small, but it's very mighty in its performance to ensure the engine's proper temperature. If you need cooling system repair, we invite you to bring your vehicle into our auto repair shop today!
