Whether you have a stock or modified Celica, you need a dependable cooling system. An unreliable and inefficient setup can lead to overheating, accelerated wear, and potential internal engine damage. The Mishimoto Toyota Celica Racing Thermostat set is precision engineered to provide your vehicle with optimal cooling efficiency by significantly decreasing high engine temperatures, even in the most demanding environments. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat opens at a lower temperature (160°F) compared to standard thermostats (180°F). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto thermostats are digitally calibrated and utilize high-quality wax for consistent and precise operation. New seals for leak-free installation are also included. This thermostat also includes the Mishimoto Lifetime Warranty
