Medium Duty Truck Maintenance Pro Tips
- Run comprehensive computer diagnostics before beginning service to identify stored codes or system irregularities requiring attention during maintenance
- Use OEM or OEM-equivalent filters for medium-duty trucks as aftermarket filters may not provide adequate protection for commercial-grade engines and systems
- Always use manufacturer-specified torque values for medium-duty components, as over-torquing can damage threads and under-torquing can lead to component failure
- Track fluid analysis results and component wear patterns to predict future maintenance needs and optimize service intervals for specific operating conditions
- Document all service procedures with photos for warranty claims and maintain detailed records for DOT compliance and fleet management analysis
- Schedule maintenance during off-peak hours to minimize commercial vehicle downtime and maximize operational efficiency for your fleet
Optimize Commercial Fleet Performance
Implementing this comprehensive 10,000 Mile Truck Maintenance Procedure is essential for maintaining peak performance, safety, and reliability in medium-duty truck operations.
