Signs of a Faulty Car Thermostat

All vehicles have a thermostat as a part of their cooling system. The thermostat plays a vital role in regulating the flow between the coolant, radiator, and engine. Although it is small in size, the job it performs is absolutely necessary to your car's overall performance.


How Does It Work?

As you probably know, coolant will flow through the engine to drive away the engine's excess heat. The thermostat sits between the engine and radiator. When the coolant is too hot, it will move the heat through the radiator. If the coolant is not too hot, the valve will stay sealed, and the coolant will continue to circulate to the block.


What Are Common Causes of a Faulty Thermostat?

Some common explanations for a malfunctioning thermostat include:

  • Coolant leaks
  • Vehicle overheating or underheating
  • Engine temperatures that fluctuate too rapidly
  • Poor engine performances
