Product Overview

This piston cooling nozzle Part No.6151‑22‑1810 is an essential engine lubrication and cooling component specially designed for Komatsu S6D125 and 6D125 diesel engine. It sprays pressurized engine oil onto the bottom of piston during engine operation, effectively dissipates high heat generated by piston combustion, reduces piston operating temperature, prevents piston overheating, scuffing and cracking, and extends service life of piston, cylinder liner and other key engine parts. Our replacement piston cooling nozzle is strictly manufactured according to OEM technical standards for direct replacement.
