Thermostat Repair and Replacement

The thermostat is an important part of your vehicle’s cooling system. Its role is to control the flow of coolant to your engine, keeping the vehicle at its optimum running temperature. The thermostat measures the temperature of your engine, opening and closing to allow / restrict the flow of engine coolant. Over time, the thermostat can break and malfunction, directly affecting the flow of coolant to your engine.

Thermostat stuck closed

The thermostat may become stuck closed, restricting the flow of coolant to your engine. This can cause the engine to quickly overheat. If your temperature gauge is reaching a critical level, it is best to pull over and let your vehicle cool down. Overheating can seriously damage your engine and result in a huge repair bill.

In this case it is far more cost effective for you to call a breakdown service such as the AA, or a friend to help you, rather than risk multiple thousands of dollars worth of damage to your engine from overheating.

 

Thermostat stuck open

The thermostat can also become stuck open, providing your engine with an ongoing flow of coolant. This will cause your engine to never reach its optimum temperature, resulting in:

  • decreased performance (power) from your vehicle
  • increased exhaust emissions (green house gasses)
  • increased fuel consumption and fuel costs
  • This will also cause the oil to never reach its optimum temperature, increasing wear on your engine over time.

 

Signs of a damaged thermostat

  • The temperature gauge takes more than 10 minutes of normal driving to get close to half way
  • The Check Engine light is on
  • The engine is overheating
  • The vehicle is under-performing
  • The output from the heater is not getting warm as quickly as normal (should be fully warm within 5 to 10 minutes normal driving)
