3155151 Oil Nozzle for Volvo FH16 D16C

What does an oil nozzle do?

This engine oil nozzle is a critical component within the crankcase lubrication system, specifically designed to manage heat and friction. It works by directing a controlled oil spray onto the underside of the piston, which effectively carries heat away from the combustion chamber and helps maintain thermal balance during heavy-duty operation.

Vehicle compatibility and engine fitment

This specific part is engineered for use in Volvo FH16 trucks equipped with D16C engines. It ensures that the piston crown and connecting rod small-end bushing receive adequate lubrication to prevent premature wear under high pressure.

Installation and maintenance

For proper installation, technicians should verify the connection style and ensure that all sealing surfaces are clean. It is essential to check that the nozzle is seated correctly within the block gallery to maintain stable oil pressure across the entire lubrication circuit.

Engine protection and performance

Maintaining this component helps prevent overheating in turbocharged diesel engines and ensures reliable engine performance for fleet managers and workshop technicians.
