The Mishimoto racing thermostat for the 1970–1973 Datsun 240Z is designed to improve cooling efficiency on stock or modified setups. Once the engine is fully warmed, it opens at a lower temperature than a standard thermostat to start coolant flow sooner, helping reduce and maintain cooler engine temperatures.
