  • Direct fit for the 1970-1973 Datzun 240Z
  • Lower activation temperature allows coolant to flow through the engine earlier, maintaining lower temperatures (Mishimoto thermostat activates at 167F vs. stock 180F)
  • Mishimoto Lifetime Warranty


The Mishimoto racing thermostat for the 70-73 Datsun 240Z will promote greater cooling efficiency in your stock or modified 240Z. Once the engine is fully warmed up, Mishimoto's Datsun 240Z racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures. The Mishimoto 70-73 Datsun 240Z racing thermostat is the perfect addition to your street or track 240Z and is a direct replacement for the stock thermostat. This thermostat includes the signature Mishimoto Lifetime Warranty.
