Semi Truck Maintenance Checklist

Take good care of your truck and it will return the favor by helping you get the job done without any problems. To keep your truck in good condition, be sure to take the following maintenance steps during the fall season.

Tires

Everything from poor weather conditions and lack of maintenance to sharp objects on the road can cause tires to wear out and even go flat. Once a week, check the tire pressure and once a month, check the tire tread. Replace your tires every three to six years, depending on how much you drive.

Brakes

Brakes on a semi-truck wear out faster than brakes on a passenger vehicle. Heavy loads and tremendous momentum add pressure to the brakes and require frequent replacement. Typically, brakes on a semi-truck last between 250,000 and 300,000 miles before they should be replaced.

Fluids

Engine oil should be replaced every 10,000 to 25,000 miles. However, the following factors can cause engine oil to burn or deplete quicker than usual:

Vehicle age
The type of terrain the truck is driving on
Frequent rapid acceleration
Leaking oil

A good rule of thumb is to inspect the oil level 5,000 miles after it has been replaced.

Fuses

A truck’s electrical system controls many crucial components, including the headlights, flashers, turn signals, brake lights, warning lights, and clearance lights. Run a quick electronics diagnosis at the beginning of the fall season to identify loose or worn out wiring.

Suspension and steering system

The suspension and steering system serves three key functions:

Ensure a smooth ride.
Keep the tires of the truck and trailer on the road and maintain traction.
Make lane changes.

The suspension and steering system should be inspected once a year for signs of potential issues.

Cooling System

The cooling system consists of the radiator caps, coolants, surge tanks, hoses, and oil coolers. The individual parts work together to transfer engine heat and control the temperature of metal parts. Be sure to inspect each of these components for corrosion, defects, and wear and tear.

Windshield Wipers

Old windshield wipers can damage the windshield and make it difficult to see during heavy rain. When blades make a scraping sound going across the windshield, it’s time to replace them.
