Part #: MMTS-TUN-07

A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 2007-2022 Toyota Tundra 5.7L cooling system with a Mishimoto Low-Temperature Racing Thermostat and housing! This thermostat is designed as a direct-fit replacement for your aged stock unit. The Mishimoto thermostat has a lower activation temperature (71 C/160 F) compared to the factory thermostat (82 C/180 F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces 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 Mishimoto Lifetime Warranty.

Features:

  • Direct fit for 2007+ Toyota Tundra 5.7L
  • Stock-style housing includes pre-installed low-temperature thermostat for easy install
  • The lower activation temperature allows coolant to flow through the engine earlier, which yields and maintains lower engine temperatures (71?C/160?F compared to the factory thermostat at 82?C/180?F)
  • Ideal for use in hot climates, on modified vehicles, or in extreme towing/driving conditions
  • Mishimoto Lifetime Warranty
