Performance Jeeps deserve Jeep performance parts. Keep temperatures under control in your rock-crawling 2012–2018 Jeep Wrangler JK 3.6L with the Mishimoto 2012–2018 Jeep Wrangler JK 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 2012–2018 Jeep Wrangler JK 3.6L thermostat opens at a lower temperature (180°F) compared to the stock unit (203°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 2012–2018 Jeep Wrangler JK 3.6L thermostats are constructed using high-quality wax for reliable, repeatable operation.
