Proper maintenance of your cooling system is essential for optimal performance and extending the life of your engine. A failed thermostat can result in overheating, accelerated engine wear, and potential internal engine damage. The Mishimoto Pontiac 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 have a classic GTO or Firebird, trust Mishimoto to keep your Poncho on the road and out of the shop! This thermostat is applicable for most V8 Pontiac engines from 1964 to 1989; for more information check out our application guide! As with all our products, this racing thermostat is guaranteed by the Mishimoto Lifetime Warranty
