Failure Symptoms

A decrease in system pressure or flow rate is often the first indication of a failing pump. If ignored, the pump may begin to leak or produce excessive noise, leading to insufficient lubrication or cooling. Continued operation risks severe engine damage due to lack of essential fluid circulation.

Installation Tip

Prime the new pump assembly with clean system fluid before installation to ensure immediate lubrication upon startup. Avoid forcing the pump onto its drive shaft, as this can damage the shaft or the pump coupling.

Service Note

Inspect the drive coupling and related fluid lines for wear or damage when replacing the Pump G assembly.
