Description

Hold your engine at its designed operating temperature with the AISIN Engine Coolant Thermostat THN006, a direct-fit replacement thermostat assembly for a wide range of Infiniti and Nissan applications. It fits many vehicles, among them the 1995-2001 Nissan Maxima 3.0L, 2009-2020 Nissan 370Z 3.7L and 2014-2018 Infiniti Q50 3.5L. See the "Vehicles it fits" section for the full list.

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.
Exact 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.
