Spring Maintenance Tips for CDL Vehicles: Prepping for warmer weather.

As winter fades and warmer weather approaches, it’s essential for commercial drivers and fleet operators to conduct thorough spring maintenance on their vehicles. Harsh winter conditions can take a toll on trucks and buses, and proper inspections and maintenance ensure safety, reliability, and compliance with DOT regulations. Here are key areas to focus on as you transition into spring driving conditions.

1. Inspect and Service the Braking System

Cold temperatures and road salt can cause corrosion and wear on brake components. Conduct a full brake inspection to check for:

• Uneven brake wear or reduced stopping power

• Corrosion or rust buildup on brake lines

• Air brake system leaks or issues with air pressure

2. Tire Inspection and Rotation

Winter driving conditions can be tough on tires, leading to uneven wear and potential damage. As temperatures rise, check:

• Tread depth to ensure compliance with safety standards

• Sidewalls for cracks, cuts, or bulges

• Tire pressure, as fluctuating temperatures can cause changes

• Consider rotating tires for even wear and longer lifespan

3. Battery and Electrical System Check

Cold weather puts a strain on batteries and electrical connections. Perform a battery test and inspect for:

• Corroded or loose terminals

• Proper charge levels and cranking power

• Faulty wiring or electrical shorts

4. Fluid Levels and Cooling System Maintenance

Warmer weather means increased engine workload. Make sure to:

• Check and top off fluids, including coolant, transmission, and power steering

• Inspect hoses and belts for cracks, leaks, or wear

• Flush and replace coolant if needed to prevent overheating

5. Suspension and Alignment Check

Potholes and icy roads can cause alignment issues and suspension damage. Conduct:

• Alignment tests to ensure even tire wear and smooth handling

• Inspections of shocks, struts, and leaf springs for signs of wear

• Greasing of moving parts to prevent wear and tear

6. Undercarriage and Frame Inspection

Road salt and winter grime can cause rust and structural damage. A thorough cleaning and inspection should include:

• Checking for corrosion on the frame, axles, and suspension

• Ensuring mud flaps, fenders, and splash guards are secure

• Cleaning and lubricating moving parts to prevent long-term damage

7. HVAC and Air Filtration System Maintenance

With warmer weather approaching, ensure driver comfort and air quality by:

• Testing the AC system for proper cooling

• Replacing cabin and engine air filters

• Cleaning out vents and air ducts to remove dust buildup

8. Lights, Wipers, and Visibility Checks

Spring showers and longer daylight hours mean visibility is key. Ensure:

• All lights are working properly, including headlights, brake lights, and signals

• Windshield wipers are in good condition and washer fluid is topped off

• Mirrors and windows are clean and free of cracks
