Preparing Your Heavy Haul Truck for Winter: Maintenance 101

Winter can test even the most robust heavy haul trucks. Preparing your vehicle for cold weather ensures safety and minimizes downtime. Here’s our in-depth guide to winterizing your truck.

Inspect the Battery and Electrical System

Cold temperatures can drain battery power, raising the risk of a truck breakdown. Test your battery's charge and consider replacing older ones. Clean terminals and ensure all connections are tight and corrosion-free. Inspect wiring for damage and check that your alternator is charging correctly, as a fully functional electrical system is essential for powering critical components.

Optimize Tires and Chains

Tires are your lifeline in icy and snowy conditions. Check tread depth—most experts recommend at least 6/32” for winter driving. Maintain proper tire pressure, as fluctuations in temperature can cause deflation. Inspect sidewalls for cracks or bulges. Always carry tire chains and ensure they are the right size for your truck’s tires. Regularly practice installing them to ensure quick readiness during adverse weather.

Maintain the Cooling System

Extreme cold doesn’t negate the need for a functioning cooling system. Inspect your radiator, hoses, and clamps for leaks or wear. Test your antifreeze mixture—most manufacturers recommend a 50/50 blend to prevent freezing. Flush and refill the coolant if it’s due for replacement.

Prepare the Fuel System for Freezing Temperatures

Diesel fuel can gel in sub-zero temperatures, leading to costly delays. Add a quality anti-gel additive at every fill-up. Drain the fuel-water separator daily to prevent ice buildup. Ensure all fuel filters are clean and consider carrying a spare in case of clogging.

Test Brakes, Lights, and Wipers

Winter driving requires peak performance from your brakes. Check for air leaks in brake lines and ensure all components are properly lubricated. Replace worn wiper blades and refill washer fluid with a winter formula to prevent freezing. Confirm all lights are working and clear for maximum visibility in snow or fog.

Stock Emergency Supplies

Prepare for the unexpected by packing an emergency kit. Include essentials like warm clothing, a blanket, non-perishable food, water, a flashlight, extra batteries, road flares, jumper cables, and a first-aid kit. Carry extra fluids such as engine oil, antifreeze, and windshield washer fluid.
