Why Replace the Secondary Oil Pump?
A failure in the lubrication system can compromise engine operation. Before replacing the pump, identify the cause of the issue: an oil pressure warning alone is not sufficient to conclude that the pump is defective. The following signs warrant an inspection:
- Oil pressure warning or abnormal value observed during diagnosis
- Pump wear or deterioration identified during inspection
- Unusual mechanical noises requiring an inspection of the lubrication system
During maintenance, check the oil level and condition and follow the manufacturer's recommendations. Replace the pump when the diagnosis or overhaul procedure justifies it, without waiting for the fault to worsen.
