Mishimoto Racing Thermostat for 1987-2006 Jeep Wrangler YJ/TJ

Upgrade your Jeep Wrangler’s cooling system with the Mishimoto Racing Thermostat, engineered specifically for 1987-2006 Jeep Wrangler YJ and TJ models. Designed for enthusiasts who demand reliable performance, this thermostat opens at a lower temperature (180°F / 82°C) compared to the factory unit (195°F / 90.5°C), allowing coolant to circulate through the engine sooner. The result is reduced and stabilized engine temperatures, which helps decrease engine wear and improve long-term reliability—especially important for Jeeps driven in warm climates, under heavy loads, or during off-road adventures.
