Failure Symptoms

Early signs of a failing oil pump include fluctuating or low oil pressure readings on the dashboard gauge. If ignored, the engine may start to produce knocking or grinding noises due to inadequate lubrication, and the oil warning light may illuminate. Continued operation without proper lubrication can lead to severe internal engine damage.

Installation Tip

Always inspect the oil pickup tube and screen for obstructions or damage before installing the new pump. Do not reuse the old gasket or seal; always use a new one.

Service Note

When replacing the oil pump, it is advisable to inspect the engine's oil pan, pickup tube, and oil filter for any debris or sludge.
