Mishimoto 2007+ Toyota Tundra 5.7L Low-Temperature Thermostat

Mishimoto is known for making well-built cooling system parts. If you're looking to keep your engine running cooler, especially in warmer climates or when your vehicle is working hard, this Mishimoto Low-Temperature Thermostat is a solid option. It's designed as a direct replacement for your stock thermostat and housing, making the swap straightforward.

This thermostat opens up at 71°C (160°F), which is notably cooler than the factory thermostat's 82°C (180°F) activation point. By allowing coolant to circulate through the engine earlier, it helps reduce and maintain lower overall engine temperatures. This can be a real benefit if you've added power to your engine, frequently tow heavy loads, or live in a hot region. The housing comes with the thermostat pre-installed, simplifying the installation process.

This part fits a wide range of Toyota and Lexus vehicles with the 5.7L engine, including models like the Toyota Tundra, Toyota Sequoia, and Lexus LX570. It's backed by the Mishimoto Lifetime Warranty, so you can install it with confidence.
