As the seasons change, it’s the perfect time to give your truck a thorough inspection. Whether recovering from a bitter-cold winter or preparing for a brutally hot summer, being proactive with preventative maintenance keeps your truck road ready and helps you avoid unnecessary component breakdowns.
Spring is the perfect time to address wear and tear from winter conditions and get ready for warmer weather. From tips on improving your cab’s air quality to replacing worn components, we’ve highlighted some of the best truck parts to help you tackle spring maintenance.

Spring Maintenance Tips
Tip #1: Replace your air filter with an OEM-approved filter to ensure better airflow. Air filters typically need to be changed every 15,000 to 30,000 miles. Although, this can vary based on factors such as driving conditions, the environment, and the type of work the truck is doing. Regularly inspect your air filters, especially if you experience reduced engine power, higher fuel consumption, or unusual engine sounds. For the most accurate guidance, always refer to your manufacturer’s maintenance schedule.
Tip #2: Get a Federal DOT inspection done by a trusted local dealer, like Coopersburg & Liberty Kenworth. Our expert Service Department is staffed with certified technicians who know trucks inside and out. They’ll ensure that your inspection is done thoroughly, efficiently, and in full compliance with federal regulations.
