When properly maintained the Jeep Grand Cherokee has proven to be an extremely reliable platform with a bulletproof engine and drivetrain. Proper maintenance of the cooling system is necessary for extended engine life and dependability. A failed thermostat can lead to overheating, accelerated engine wear, and potential internal engine damage. The Mishimoto Jeep Grand Cherokee Racing Thermostat is precision engineered to provide your vehicle with years of reliable service and optimal cooling efficiency even in the most demanding environments. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (180°F) compared to standard thermostats (195°F). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto thermostats are digitally calibrated, utilize high-quality wax to ensure precise and consistent opening temperatures, and include a gasket for seamless, leak-free installation. Whether you use your Jeep for general commuting or for weekend trips to the campsite or trail, trust the Mishimoto thermostat to keep your Jeep performing like new! As with all our products, this racing thermostat is guaranteed by the Mishimoto Lifetime Warranty
