As winter approaches and holiday demand ramps up, fleet managers face the challenge of keeping vehicles safe and operational in freezing temperatures. Preventive maintenance is the key to avoiding costly breakdowns and ensuring on-time deliveries. Here are six critical areas to focus on for winter fleet maintenance:
1. Batteries & Charging Systems
Cold weather strains batteries and they are crucial to starting a truck in the winter temperatures. Perform load tests, clean terminals, and verify charging systems to prevent no-start issues.
2. Air Dryer System
Commonly overlooked in the warm months, air dryers prevent moisture-related failures in air brake systems. Inspect for leaks, drain tanks regularly, and follow OEM maintenance guidelines.
3. Cooling System
Check antifreeze levels for proper freeze protection, maintain a 50/50 coolant mix, and inspect belts, hoses, and block heaters.
4. Cab & Driver Safety
Ensure wipers, washer fluid, heated mirrors, and safety kits are ready for winter conditions. Nothing is more important than the safety of your driver, and it starts with the equipment they are operating.
5. Fuel Treatment
Prevent fuel gelling with blended fuels or additives. Check fuel heaters and prepare for varying climates.
6. Tires
Monitor tire pressure and tread depth—cold temperatures cause pressure drops, impacting traction and safety.
