This is a Genuine Nissan upper radiator cap pipe fitting, designed specifically for the Nissan Navara D23 NP300. Located on the top passenger side of the radiator, it serves as a critical junction, providing the mounting point for the radiator cap and the connection for the upper radiator hose.
Over time, constant heat and pressure cycles in the engine bay cause the original plastic fitting to become brittle and crack. This compromises the cooling system's ability to hold pressure, leading to symptoms like visible cracks, coolant leaks, or engine overheating. Using a Genuine Nissan part is critical, as cheaper aftermarket alternatives often use inferior plastics that can fail prematurely, risking catastrophic coolant loss and severe engine damage.
Replacement is a straightforward job for a workshop or an experienced home mechanic. The process involves partially draining the cooling system to access the fitting, swapping the part, and refilling with fresh coolant. While you have the system open, it is a good idea to inspect the radiator cap, upper radiator hose, and hose clamps for any signs of wear. You will require fresh engine coolant to top up the system upon completion.
