AISIN Engine Coolant Thermostat P/N:THN-006

Description

Hold your engine at its designed operating temperature with the AISIN Engine Coolant Thermostat THN006, a direct-fit replacement thermostat assembly for a long list of Infiniti and Nissan V6 (and one L4) applications. It drops in on the 2009-2020 Nissan 370Z [V6-3.7L], 1995-2001 Nissan Maxima [V6-3.0L] and 1996-2001 Infiniti I30 [V6-3.0L], plus a wide range of Infiniti models including the 2014-2018 Q50 [V6-3.5L], 2014-2018 Q70 [V6-3.5L], 2009-2013 G37 [V6-3.7L] and 2014-2017 QX60 [L4-2.5L] — see the Buyer's Guide tab for the full list of 22 applications.

A thermostat stays closed while the engine warms up, then opens to route coolant to the radiator, regulating flow to keep temperature in the intended range. If a thermostat stuck open (slow warm-up, low temp) or stuck closed (overheating) is the cause of your trouble, this replaces it.

OE-engineered assembly: built as an exact-replacement thermostat assembly for OE form, fit and function.
Calibrated opening temperature: designed to open at the exact temperature to maintain cooling system performance.
Temperature control: helps keep coolant within the optimal temperature range.
Country of origin: Japan.
