The Mishimoto racing thermostat for the 2009–2020 Nissan 370Z opens at 155°F (68°C) to promote earlier coolant flow and lower stabilized engine temperatures. It’s intended for higher-demand or modified applications where reduced operating temperature improves cooling efficiency. By opening sooner than standard thermostats, this unit helps the cooling system circulate coolant earlier during warm-up, aiding temperature control under sustained or elevated engine loads.
