⚙️ Technical Insights
The 3013591 piston cooling nozzle delivers lubricating oil toward the underside of the piston. Therefore, it helps remove heat from the piston assembly and supports stable operation under high combustion temperatures. Documented parts information identifies this component as a piston cooling nozzle for compatible 855-series diesel engines.
Moreover, correct nozzle positioning and unobstructed oil flow are important for effective piston cooling. A damaged, blocked, or incorrectly installed nozzle can reduce cooling performance and increase thermal stress on internal engine components. For this reason, technicians should inspect the nozzle during piston, connecting rod, or engine overhaul work.
🛠 Application Scenarios
The 3013591 piston cooling nozzle is used in compatible heavy-duty diesel engine applications, with documented fitment in NH and NT855 configurations. It also appears in parts documentation for related 855-series engine assemblies.
It is suitable for piston replacement, engine rebuilding, lubrication-system maintenance, and major overhaul work. In addition, replacing a worn or damaged nozzle can help restore proper oil delivery to the piston cooling area.
📦 Availability
The 3013591 Piston Cooling Nozzle is available as a replacement component for compatible diesel engine applications. Before ordering, please confirm the part number and engine configuration to ensure correct fitment.
For correct fitment, please provide your equipment model, engine model, or existing piston cooling nozzle number. In addition, our support team can help verify the appropriate piston cooling nozzle for your application.
