Mishimoto low-temperature thermostat and housing for 2007–2022 Toyota Tundra 5.7L replaces the stock unit with a lower activation temperature (71°C/160°F versus factory 82°C/180°F) to allow earlier coolant flow. Intended for use in warmer climates, modified vehicles or heavy towing, the thermostat installs in the stock-style housing for correct sealing and easier installation while helping to reduce operating temperatures under demanding conditions.
