A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 2007+ Toyota Tundra 5.7L cooling system with a NTCL Low-Temperature Racing Thermostat and housing! This thermostat is designed as a direct-fit replacement for your aged stock unit. The NTCL thermostat has a lower activation temperature (68 degrees) compared to the factory thermostat (82 degrees C/180 degrees F). The lower activation temperature allows coolant to flow through the engine earlier, which yields and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates, on vehicles making more power than stock, or under extreme towing/driving conditions. The stock-style housing will provide a proper seal and installs easily. Like all our Toyota Performance parts, this thermostat and housing includes the NTCL Lifetime Warranty.
