This Mishimoto racing thermostat fits both the 1989-2002 Nissan RB Series engine and the VG30DE(TT) engine. It is designed to promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.

Mishimoto Thermostat Activates at 68º C (155º F)

OEM Thermostat Activates at 76.5º C (170º F)

Note: This thermostat does not come with a gasket. On the VG30 models, Nissan recommends using Gray RTV around the thermostat housing to properly seal it.
