Pro Tips for Medium Duty Truck Maintenance
- Pre-Service Diagnostics: Run comprehensive computer diagnostics before beginning service to identify any stored codes or system irregularities that may require attention during maintenance.
- Filter Quality Matters: Use OEM or OEM-equivalent filters for medium-duty trucks as aftermarket filters may not provide adequate protection for commercial-grade engines and systems.
- Torque Specifications: Always use manufacturer-specified torque values for medium-duty components, as over-torquing can damage threads and under-torquing can lead to component failure.
- Documentation and Trends: Track fluid analysis results and component wear patterns to predict future maintenance needs and optimize service intervals for your specific operating conditions.
