Introduction
Preventive Maintenance Schedule A is the foundation of successful fleet management, performed every 5,000 miles to maintain optimal vehicle performance and extend service life. This basic maintenance service includes critical tasks such as engine oil changes, filter replacements, tire inspections, and comprehensive fluid level checks that prevent costly breakdowns and ensure safe operation of light and medium-duty commercial vehicles.
Following this Schedule A preventive maintenance checklist as part of your fleet maintenance routine helps identify minor issues before they become major problems, reduces unexpected downtime during critical operations, and maintains regulatory compliance. The checklist aligns with manufacturer specifications, DOT requirements, and industry best practices for fleet vehicle maintenance in delivery, commercial, and utility service applications.

Pro Tips for Schedule A Maintenance
- Timing Matters: Perform Schedule A maintenance within 200 miles of the 5,000-mile interval to maintain optimal engine protection and warranty coverage. Early service is better than late service.
- Quality Parts: Use OEM or equivalent quality filters and fluids that meet manufacturer specifications. Cheaper alternatives may save money upfront but can lead to costly repairs later.
- Documentation: Maintain detailed service records including part numbers, fluid types, and mileage. This documentation is essential for warranty claims and helps identify recurring issues.
- Visual Inspection: While performing routine tasks, always conduct a thorough visual inspection of the vehicle. Many potential problems can be caught early through careful observation.

Detailed Service Procedures
Follow these structured procedures to ensure a thorough Schedule A maintenance service. These procedures should be adapted to your specific vehicle make and model requirements.
Oil Change Procedure
- Warm engine to operating temperature for complete oil drainage
- Position drain pan and remove drain plug with proper tools
- Allow oil to drain completely (15-20 minutes minimum)
- Remove old filter using proper filter wrench
- Clean filter mounting surface and apply thin oil coat to new gasket
- Install new filter hand-tight plus 3/4 turn additional
- Replace drain plug with new gasket, torque to specification
- Add correct oil type and quantity per manufacturer specs
Tire Pressure and Inspection
- Check tire pressure when tires are cold (not driven for 3+ hours)
- Use calibrated pressure gauge for accurate readings
- Inflate to door placard specification, not sidewall maximum
- Inspect tread pattern for uneven wear indicating alignment issues
- Use penny test or tread depth gauge to measure remaining tread
- Check sidewalls for cracks, bulges, or weather damage
- Examine valve stems for cracks and ensure caps are tight
Fluid Level Verification
- Check coolant level in overflow tank when engine is cold
- Verify brake fluid is at maximum line and clear in color
- Check power steering fluid with engine running at idle
- Measure transmission fluid with engine warm and running
- Use dipstick or sight glass for differential oil level
- Fill windshield washer reservoir with appropriate solution
- Document any fluid condition concerns or leaks found
Battery Service Procedure
- Disconnect negative cable first, then positive cable
- Clean terminals with battery terminal cleaner or baking soda solution
- Inspect battery case for cracks or damage
- Load test battery to verify capacity meets specifications
- Check specific gravity if serviceable battery type
- Apply terminal protectant after reconnection
- Reconnect positive cable first, then negative cable
- Verify charging system operation with engine running
