Keep temperatures under control in your rock-crawling JK with the Mishimoto Jeep Wrangler 3.6L Racing Thermostat. A faulty thermostat can result in engine overheating and potential internal damage. Protect your Pentastar by upgrading to the Mishimoto low-temperature thermostat. This thermostat opens at a lower temperature (180 degree F) compared to the stock unit (203 degree F), which allows coolant to flow through the system earlier. By doing so this thermostat will reduce and maintain lower engine coolant temperatures, making it ideal for use in warm climates or under extreme driving/towing conditions. All our thermostats are constructed using high-quality wax for reliable, repeatable operation. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty.
