Why Your Fleet Needs a Structured Maintenance Checklist

Implementing a systematic approach to fleet maintenance offers numerous benefits that directly impact your bottom line:

✅ Reduced downtime: Every hour a vehicle spends in unplanned maintenance represents lost productivity and revenue. Regular maintenance prevents unexpected breakdowns that take vehicles off the road.
✅ Extended vehicle lifespan: With the rising costs of new vehicles, extending your fleet’s useful life has never been more important. Consistent care helps vehicles last significantly longer, maximizing your return on investment.
✅ Improved safety: Well-maintained vehicles dramatically reduce the risk of accidents caused by mechanical failures, keeping drivers, passengers, and others on the road safe.
✅ Better fuel efficiency: In an era of fluctuating fuel prices, efficiency matters more than ever. Properly maintained engines, correct tire pressure, and clean filters can significantly improve fuel economy.
✅ Lower repair costs: Preventive maintenance is consistently more cost-effective than reactive repairs. Catching small issues early prevents them from becoming expensive problems.
✅ Enhanced compliance: Transportation regulations continue to evolve and become more stringent. Regular maintenance helps meet regulatory requirements and avoid costly violations and penalties.

• Broken lights or signals
• Windshield cracks or chips

Fluid Levels

Tire Condition:

• Pressure check (including spare) against manufacturer specifications

• Look for unusual tire wear indicating alignment issues
• Inspect bushings for deterioration
• Lubricate all grease fittings

Fuel system maintenance:

• Replace fuel filter according to schedule
• Inspect fuel lines for leaks, cracks, or rubbing
• Check for fuel pump noise or long cranking
• Consider fuel injector cleaning service if performance has decreased
• Test fuel cap seal integrity

Cooling system inspection:

• Pressure test for leaks
• Test coolant freeze/boil protection level
• Inspect water pump operation
• Check radiator and heater core for obstructions
• Verify thermostat operation
• Test cooling fans for proper cycling

---

Semi-Annual Checks

Time: 2h to 3h per vehicle
