The thermostat in your Toyota vehicle has one role, and it does it rather well. It's responsible for regulating the temperature of your engine. It does this in response to coolant temperature changes.

How an Automotive Thermostat Works

The thermostat features a wax that expands when the engine temperature gets too high. That expansion opens a value that allows coolant to flow from the radiator to the engine, where it collects the engine heat. The coolant then returns to the radiator, where the heat is dispersed through the radiator's flat surface into the atmosphere.

How to Spot a Failing Thermostat

Thermostats don't go bad often, but there are signs of failure. These include:

  • The "Check Engine" dash light engages
  • Your engine begins to overheat
  • The engine runs less efficiently
  • You have HVAC problems
