Thermostat

The Toyota thermostat in the engine acts as a regulation valve that controls the flow of coolant. It is imperative that the engine is allowed to reach a specific temperature before coolant is sent to it. The thermostat controls the amount of coolant going to the radiator and makes it run efficiently, so it's definitely not a part to ignore if there are issues. If your OEM thermostat is going bad, you will see several warning signs. You might notice a high-temperature reading that jumps up within the first fifteen minutes of starting the car. This is known as being in the "red zone" and should be taken extremely seriously. There could also be a low-temperature reading resulting in an underheated engine. Watch for the temperature changing erratically or coolant leaks that signify a problem. If you ignore these signs, you might end up stranded on the side of the road with an engine that isn't working properly. To keep your Toyota's engine running smoothly, you want to replace the defective part with an OEM replacement thermostat. Only OEM thermostats are going to fit the make and model of your vehicle perfectly and allow you to be confident during the installation process.
