Great Material: This product is made of ABS. This material offers uniform structural strength and stable physical properties, making it resistant to deformation caused by normal external forces. It maintains its shape over the long term, making it suitable for replacing coolant system components and meeting long-term usage requirements without concerns about material stability.
Application: This product has an outer diameter of 1.46 inches, an inner diameter of 1.16 inches, and a height of 0.41 inches. The product is compatible with the 2011–2025 Altima, 2011–2023 Maxima, 2025 Murano, 2013–2025 Pathfinder, 2013–2016 JX35, and 2014–2018 QX60. It serves as a direct replacement for OEM part number #21712-ZN50A.
Easy Installation: Before installation, thoroughly clean the coolant reservoir opening and ensure the surface is smooth. Align the cap horizontally with the opening, then screw it in smoothly and evenly. Keep the cap perpendicular to the opening throughout the tightening process to prevent tilting or jamming. Finally, tighten until it is fully seated against the reservoir opening and confirm there is no play.
Sealing Performance: This product creates a uniform and consistent seal on the coolant reservoir opening, effectively reducing coolant evaporation and leakage, and preventing coolant loss caused by poor sealing. Stable sealing performance ensures the basic operational condition of the coolant system and reduces the likelihood of system malfunctions caused by insufficient coolant.
Secure Fixation: This product features a screw-on design that forms a tight and secure connection with the reservoir opening when tightened, reduce the possibly of loosening or detachment caused by vehicle vibrations during operation. The threaded design prevents shifting once tightened, ensuring the cap remains firmly in place—even on rough roads—and maintaining a stable installation.
