Winter brings unique challenges for heavy-duty fleets. Cold weather, road chemicals, and freezing conditions put extra strain on tanks and trailers. Proper winterization is essential to prevent breakdowns, protect equipment, and keep freight moving safely.

Why Winterization Matters
Tank and trailer systems are exposed to the harshest road and weather conditions. Without preparation, fleets risk costly downtime, frozen components, or even compliance violations. Winterizing is not just about safety, it is about extending equipment life, reducing emergency calls, and ensuring on-time deliveries.
Key Steps to Winterize Your Tank and Trailer Fleet
1. Inspect and Protect Braking Systems
Moisture in air lines can freeze and block airflow. Regularly drain air tanks, inspect for leaks, and confirm that valves and fittings are in top condition.
2. Safeguard Fuel and Hydraulic Systems
Diesel fuel can gel in extreme cold. Using a winter-grade fuel additive helps prevent filter clogs. Hydraulic systems should be checked for leaks, and fluids must meet cold-weather specifications to keep pumps and valves moving smoothly.
3. Check Tires and Tread Depth
Traction is everything on icy roads. Ensure proper tread depth, check tire pressure frequently, and consider winter-rated tires for added grip.
4. Maintain Cooling and Heating Components
Inspect radiators, hoses, and antifreeze levels to prevent freezing. For tanker operations, confirm that heater systems are functioning properly to protect sensitive loads.
5. Electrical Systems and Lighting
Cold weather is hard on batteries and wiring. Test voltage, clean connections, and confirm all lights and reflectors are clean and working to improve visibility on darker winter roads.
6. Preventive Cleaning and Lubrication
Salt and road chemicals accelerate corrosion. Washing trailers regularly and applying lubrication to moving parts, such as landing gear, hinges, and suspension components, helps prevent costly wear.
Added Protection with Emergency Prep
Even with the best maintenance, winter emergencies happen. Equip every unit with an emergency kit that includes warm gear, fluids, lighting, and tools to keep drivers safe while waiting for service.
