Failure Symptoms

The first indication of a failing oil pump might be a fluctuating or low oil pressure reading on the gauge. If ignored, the pump can fail to supply adequate lubrication, leading to increased friction, overheating, and significant internal engine damage. Continued operation without proper lubrication risks catastrophic engine failure.

Installation Tip

Ensure the oil pickup tube screen is clean and properly seated before installing the new oil pump. Prime the new oil pump with clean engine oil before installation to ensure immediate lubrication upon startup.

Service Note

Inspect the engine oil pan, pickup screen, and crankshaft for wear when replacing the oil pump.
