Engine Cooling Upgrade. The Mishimoto Racing Thermostat opens at 180°F, significantly lower than the stock thermostat's 212°F, enabling coolant to circulate through the engine sooner. This helps maintain cooler engine temperatures, enhancing performance and reliability under racing or demanding conditions.
Construction and Appearance. Precisely engineered to meet racing specifications, this thermostat is made from high-quality materials that ensure durability and reliability. It features a clean, functional design that directly replaces the factory thermostat, seamlessly integrating with existing cooling systems.
Installation. This direct-fit thermostat installs easily without any modifications or drilling. It replaces the stock thermostat and requires compatible GM housings (part numbers 12657137 or 12671393) for installation.
Warranty. The product includes a lifetime limited warranty.
Application. Designed specifically for 2015-2020 Yukon models with LT1, L83, L86, LV1, and LV3 engines. Intended for racing applications only.
