This is the genuine Nissan thermostat and housing assembly, designed as a direct replacement for the Nissan Navara D23 NP300 fitted with the M9T or YS23 2.3L twin-turbo diesel engine. As a critical component in the cooling system, this assembly regulates engine temperature by controlling the flow of coolant. It is a complete unit that includes the thermostat, housing, and water outlet.
Located at the front of the engine where a primary radiator hose connects, this assembly is designed to replace the original unit which can fail over time. The factory plastic housing can become brittle from constant heat cycles, leading to cracks and coolant leaks. Internally, the thermostat can fail by sticking open, preventing the engine from reaching optimal temperature, or sticking closed, which can cause rapid overheating. Replacing a faulty unit is essential for maintaining engine health.
Replacement is a moderate workshop job that requires the cooling system to be drained before installation. While replacing the housing, it is highly recommended to inspect the connecting radiator hoses and clamps for any signs of perishing or wear. You will require fresh engine coolant to refill the system once the new assembly is fitted.
