Upgraded VQ40 Thermostat & Housing 170 degree

This is our preferred low temp thermostat upgrade for Nissan VQ40 engines.

This OEM Nissan Thermostat is originally from the 2003-06 Nissan 350Z and features the same fit as as the standard Thermostat for the VQ40 but with a lower opening temp of 170° F compared to the factory VQ40 177° - 182° F opening.

Alternatively a Nismo Thermostat can also be fitted which has an opening temp of 154.4° F, only recommended for use in the most extreme cases, the low operating temp can have a negative impact on power output and fuel economy in many cases.

Mishimoto Low temp thermostats for VQ feature an opening temp of 143.6° F and are also only recommended for extreme cases.

• 2005-2012 Nissan Pathfinder (4.0L V6 VQ40DE)
• 2005-2015 Nissan Xterra
