Description

A piston cooling nozzle, also known as a spray jet, part 405325 3959291 4937305 4944337 4987915 is a component found in diesel engines that sprays oil onto the underside of the pistons. This helps to cool and lubricate the pistons, which can reach extremely high temperatures during engine operation. The nozzle is typically located in the engine block and sprays oil directly onto the piston skirts. The spray pattern and flow rate of the nozzle are carefully designed to ensure proper cooling and lubrication without compromising engine performance. A faulty piston cooling nozzle can lead to overheating, increased wear on engine components, and reduced overall efficiency of the engine. Replacement parts should always be sourced from reputable manufacturers to ensure proper fitment and performance.
