It sprays engine oil onto the underside of the piston to carry heat away from the piston crown under load. The nozzle mounts to the block with a separate check valve bolt.

Benefits

Piston cooling matters most when the engine works hard. Heavy towing and high boost put the most heat into the pistons, and a bent, cracked or loose nozzle can't aim oil where the piston needs it. Replace if worn or damaged, and check the nozzles whenever the oil pan or crankshaft is out for a rebuild. The nozzle installs with the Oil Nozzle Check Valve, Duramax | 2001 - 2016, sold separately.
