The Buick Rainier Thermostat by Mishimoto is designed specifically for the 2004-2006 models and is a racing low-temperature thermostat set to activate at 160°F. This high-performance thermostat is the perfect upgrade for automotive enthusiasts looking to enhance their vehicle's cooling system and maintain optimal engine performance.

This Mishimoto thermostat is engineered to open at a significantly lower temperature than standard thermostats, which typically begin operation at 186°F. By initiating coolant flow earlier, it ensures cooler engine temperatures, reducing the risk of overheating that can lead to engine damage.

The low-temperature functionality is especially beneficial for high-performance driving, providing additional temperature control and stability.
