This is the complete thermostat and housing assembly for the Nissan Navara D23 NP300 fitted with the M9T 2.3L twin-turbo diesel engine. The thermostat is a critical component of your cooling system, regulating engine temperature by controlling coolant flow to the radiator. The original plastic housing can become brittle with constant heat cycles, leading to cracks and coolant leaks. The thermostat itself can also fail, either sticking open and preventing the engine from reaching operating temperature, or sticking closed and causing rapid overheating. A leaking housing or failed thermostat can lead to catastrophic engine damage, including warped cylinder heads, if not replaced promptly.
