Whether your Avenger is stock or modified, you need a dependable cooling system. An unreliable and inefficient setup can lead to overheating, accelerated wear, and potential internal engine damage. The Mishimoto Dodge Avenger Racing Thermostat is precision engineered to provide your Dodge with 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 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. As with all our products, this racing thermostat includes the Mishimoto Lifetime Warranty
