Managing a fleet of trucks is no small task—balancing costs and ensuring safety can be challenging. At the end of the day, your business might be 100% dependent on your trucks staying on the road day in and day out. However, regular fleet maintenance is the key to keeping operations seamless.
If you’re looking to optimize your fleet’s performance and extend the lifespan of your vehicles, partner with NWD Performance as your northwest diesel specialist in the Marysville and Everett area.
Why Preventive Maintenance Matters
If your trucks are not on the road, then that is going to be lost revenue. The overall goal is going to help reduce downtime.
A proactive approach helps you catch minor issues before they become major, unplanned repairs. Proper fleet maintenance prevents expensive part replacements and emergency breakdowns. And of course, regular checks will help ensure your vehicles meet industry regulations and safety standards.
Key Components to Inspect Regularly
There are some important aspects that can be done weekly by anyone that is routinely driving a fleet truck to help prevent any early issues from popping up.
Engine Health is always going to be the primary concern for fleets that are continually raking up miles or spending large amounts of time idling. Just like any car, ensuring oil levels are proper and filters change intervals are done on time to prevent sludge buildup and maintain lubrication. For diesel fleets, pay attention to glow plugs, fuel injectors, and turbo components.

Maintain proper tire pressure and tread depth to improve fuel efficiency and reduce wear.
Inspect suspension systems to ensure a smooth ride, especially for long-haul or heavy-duty operations. Schedule brake inspections to replace pads, rotors, or hydraulic components before they fail. In heavy trucks, robust braking systems are essential for safety, especially when towing or hauling.
Check coolant levels and hoses to avoid overheating, a leading cause of engine damage.
Keep exhaust systems in good shape—especially important in diesel engines for emissions compliance.
Scheduling for Maximum Uptime
Trucks and anything in your fleet being down unexpectedly is a worst-case scenario. For that reason, we recommend building out a maintenance calendar. NWD Performance can work with you on that front, creating a clear, consistent schedule for oil changes, inspections, and part replacements ensuring project timing can be built around your windows. One thing to keep in mind is the need for seasonal adjustments. For us here in the Pacific Northwest, trucks should be prepared for colder, wetter weather by adjusting fluid types and inspecting battery health.
Cost Benefits of Regular Fleet Maintenance
Well-maintained engines—especially diesel powertrains—run more efficiently, can help create a bit of saving on long-term fuel costs. The real benefit of keeping a well-maintained fleet of diesel trucks is in extending the truck’s lifespan. This pays off by pushing the need to purchase new or replace trucks, but also can delay the need for costly major repairs of high mileage components.



Unexpected failures and trucks being down for unplanned maintenance needs can also hurt your bottom line since jobs would need to be delayed or cancelled. Proactive checks limit unexpected failures, minimizing unplanned expenses and protecting your diesel fleet through fleet maintenance management.
