1163254 Jet As- Piston Cooling — Cat 3508 3512

This piston cooling jet is a critical component within the engine's lubrication and cooling system, designed to spray oil onto the underside of pistons. It ensures proper heat dissipation and lubrication, preventing premature wear and thermal damage to engine internals. A failing jet may lead to increased engine oil temperature, knocking sounds, and reduced engine power.

Failure Symptoms

The first sign of a failing piston cooling jet is often an increase in engine oil temperature. If ignored, this can lead to increased engine noise, such as knocking, and a noticeable loss of power. Continued operation without addressing the issue risks severe internal engine damage.

Installation Tip

Ensure all oil passages are clean and free of debris before installing the new jet to prevent immediate blockage. Avoid overtightening the jet, which can damage the threads in the engine block.

Service Note

Inspect the oil pump and oil filter for any signs of contamination or wear when replacing the piston cooling jet.
