This 5257526 Piston Cooling Nozzle is a professional replacement component specifically tailored to fit Cummins ISF2.8 and ISF3.8 series engines, serving as a critical thermal management element in the engine’s piston system. Meticulously manufactured to align with the exact dimensional and functional requirements of target models, it ensures seamless integration and consistent performance in directing cooling oil to key piston surfaces, safeguarding against thermal damage and maintaining optimal engine operating temperatures.
Core Product Specifications
Crafted from premium heat-resistant and corrosion-resistant alloy materials, this piston cooling nozzle boasts exceptional structural durability and pressure-bearing capacity. Its precision-drilled oil passages and optimized spray pattern ensure targeted, uniform oil distribution to the piston crown, skirt, and wrist pin—effectively dissipating extreme heat generated during combustion. The robust material composition withstands operating temperatures up to 220°C and oil system pressures up to 10 bar, resisting deformation, clogging, and wear even under harsh engine working conditions.
Beyond efficient cooling, this nozzle maintains stable oil flow rates to prevent piston scuffing, seizure, or thermal fatigue—key to preserving piston integrity and engine performance. Its compact, lightweight design (only 0.038KG) and standardized mounting structure allow for quick, straightforward installation—no specialized tools or modifications are needed, making it suitable for both professional mechanics and DIY maintenance enthusiasts.
As a cost-effective and dependable maintenance solution, the 5257526 Piston Cooling Nozzle is essential for regular engine servicing, piston system overhauls, or replacement of clogged, damaged, or inefficient nozzles. It meets or exceeds industry performance standards, ensuring consistent thermal management, reduced engine downtime, and enhanced overall reliability for your Cummins ISF2.8/ISF3.8-powered equipment.
