Winter weather can be tough on commercial trucks, and preparing your vehicle for colder temperatures is essential to avoid breakdowns, increase safety, and protect your business’s bottom line. At Criswell Commercial Trucks in Germantown, MD, we know that proactive winter maintenance helps your commercial vehicle stay reliable and road-ready all season long. Whether you’re headed to job sites in snow, ice, or freezing rain, proper winter maintenance helps protect critical systems and keeps your truck performing when you need it most.
Inspect Tires, Pressure, and Tread for Winter Conditions
Proper tires are one of the most important defenses against slippery winter roads. Cold temperatures naturally lower tire pressure, which can affect handling, fuel economy, and tire wear, so it’s important to check tire pressure regularly and inflate to the manufacturer’s recommended PSI. Inspect tread depth and overall tire condition, as deeper tread provides better traction on snow and ice. In severe conditions, winter-ready tires or tire chains can offer added grip and improved safety.
Check Battery Health and Cold-Weather Starting Power
Cold weather places additional strain on your truck’s battery, reducing its ability to start the engine and power electrical components. Testing the battery for cold-cranking amps, inspecting terminals for corrosion, and replacing older batteries before they fail can help prevent unexpected winter breakdowns. A strong battery is essential for reliable starts and dependable operation during freezing temperatures.
Monitor Coolant, Fluids, and Fuel System Performance
Antifreeze and coolant play a critical role in preventing engine freeze-ups during winter. Coolant levels and freeze protection should be checked to ensure your cooling system is ready for cold conditions. Belts, hoses, and fluid levels should also be inspected, as cold temperatures can cause rubber components to become brittle. For diesel trucks, winterized fuel and anti-gel additives help prevent fuel from thickening or gelling, which can restrict fuel flow and impact performance.
Test Brakes, Lights, Heating, and Defrost Systems
Winter driving requires dependable stopping power and clear visibility. Brake inspections should include pads, rotors, and brake lines to ensure they are in good condition for slippery roads. All exterior lights should be tested to maintain visibility during snow, fog, and shorter daylight hours. Heating and defrost systems should also be checked to keep drivers comfortable and windshields clear during winter operations.
