Preventive Maintenance Recommendations for Scania DI09
We build maintenance plans around how your vessel actually operates, but as a general guideline:
- Every 100 hours: Oil & filter, visual checks of belts, hoses, coolant, and leaks.
- Every 250 hours: Fuel filters, seawater pump inspection, basic injector and exhaust checks.
- Every 500 hours: Valve adjustment, turbo inspection, full EMS & sensor review.
- Annually: Heat exchanger/charge air cooler cleaning, full system diagnostics, corrosion inspection.
Staying ahead on service dramatically reduces the risk of mid-season downtime and protects your investment.
