Product details
Keep temperatures under control in your Jeep with the Mishimoto Jeep Wrangler JK 3.6L Thermostat with Housing. A faulty thermostat can result in engine overheating and potential internal damage. Protect your ride by upgrading to the Mishimoto low-temperature thermostat, featuring an upgraded aluminum housing and galvanized steel bleeder screw for enhanced durability. This 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 thermostats are constructed using high-quality wax for reliable, repeatable operation. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship. Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit. Thermostat, 180F, w/Housing, fits Wrangler JK 2012-2018
