Description:
A properly functioning and correct temperature thermostat is critical to ensure your engine not only runs properly, but also efficiently. Too high of a temperature rating (or sticking closed) can lead to performance loss and overheating. Too low (or sticking open) and your engine may struggle to reach operating temperature, resulting in poor fuel economy. Alternatively, higher temperature thermostats can help engines reach operating temperature faster (especially in cold areas) while lower temperature thermostats can help engines stay cooler for longer. While newer engine designs are typically a bit less sensitive to ambient temperature (to a degree), climate, engine conditions, and performance modifications can all change what thermostat temperature is ideal for your Z (high efficiency radiators often work best with higher temperature thermostats when used as a daily driver or in cooler ambient areas, as an example). Gasket and hardware not included; see Related Items.

Temperature & Usage Note:
This genuine, original equipment (OEM) thermostat is designed to open at 76.5°C (~170°F). Unlike early model Z-Cars, Nissan specifies this temperature for all driving conditions regardless of climate. It is suitable for use in just about every application short of forced induction, heavily modified, or racing builds. In these uncommon cases, we recommend consulting your Race Engineer to determine whether a lower temperature thermostat is needed.
