• OE-spec replacement needs for Nissan and INFINITI cooling systems

Installation Notes and Tips

Verify the thermostat temperature specification and housing style before installation. This unit uses an O-ring seal and includes gasket/seal components where applicable, so clean the sealing surfaces thoroughly before assembly. Confirm the bypass diameter, flange dimensions, and OE temperature requirement for the vehicle application before replacing the thermostat. For Nissan Rogue, Rogue Select, and X-Trail applications, review the vehicle notes carefully because some fitments use thermostats located at the water inlet and outlet.
