DINGTONG Replacement Engine Thermostat - Keep your car running smoothly.
What Is Engine Thermostat?
A thermostat reduces engine wear, deposits, and emissions by letting the engine warm up quickly.
Designed to monitor and maintain optimal engine temperature, the thermostat in most cars is only about 2 inches (5 cm) in diameter. It may be small, but it plays a vital role in preventing an engine from running too hot or too cold.
Why You Need Change?
A functional thermostat is essential for a number of reasons, including:
- Enhanced performance: By maintaining the engine at its ideal temperature, the thermostat ensures that the engine runs efficiently. This leads to smoother performance and can even boost fuel efficiency.
- Reduced emissions: engines that operate within their optimal temperature range produce fewer emissions.This is because the combustion process is more complete, reducing the release of harmful pollutants.
- Prevention of overheating: Overheating is one of the most common causes of engine damage.The thermostat helps prevent this by ensuring that coolant circulates through the engine when it reaches high temperatures.
- Prolonged engine life: By preventing extreme temperatures, the thermostat contributes to the longevity of the engine and its components. This can save car owners significant money in repair and replacement costs over time.
When Should It Be Serviced?
A malfunctioning thermostat can lead to various issues, including engine overheating, under heating, or erratic temperature fluctuations. Some signs that may indicate a faulty thermostat include:
- Engine overheating
- Engine running too cold
- Fluctuating engine temperatures
- Unusual temperature gauge readings
- Increased fuel consumption
How It's Done?
Every liquid-cooled car engine has a small device called the thermostat that sits between the engine and the radiator. It serves as a valve to control coolant flow, and is designed to open and close at specific temperatures.
When the engine is cold, the thermostat remains closed, blocking the flow of coolant to the radiator, allowing the engine to warm up quickly to its optimal temperature.

Fits perfectly in my 2007 4Runner. OEM quality. Comes with an o-ring gasket. My only concern is it is plastic and wear and tear it may not hold up.

I got this thermostat to replace the original OEM one in the course of routine maintenance. This part matched the OEM thermostat. It comes with the o-ring gasket. After installing and testing, the engine stayed within its normal operating temperature range. The time it took to warm up was normal. The housing of this thermostat is plastic, though the build quality appears to be good. My only concern is how it will hold up over time. Of course, I can't know this until it either fails or when it's time to change it out again, whichever comes first. As of now, this product performs as it should.
