Signs Your Diesel Truck Needs Maintenance

by | Nov 15, 2022

Whether you already own a diesel-powered truck or you’re thinking of purchasing one in the near future, it’s important to know when your diesel truck needs maintenance. After all, even though many diesel engines can go longer between services than their gas counterparts, that doesn’t mean they don’t need service at all.


If you’ve owned gas-powered cars or trucks prior to this, you’re probably already familiar with our preventive maintenance philosophy: Following a regular maintenance schedule can help you catch small problems before they become bigger, more expensive ones. The same advice holds true for diesels. Give them the care and attention they deserve and they’ll often last longer and have fewer problems along the way.

How do you know when your diesel truck needs maintenance?

We’ve already established that regular maintenance is a good thing. Now, we need to talk about when that maintenance should be done.


First, follow the preventative maintenance schedule recommended by your owner’s manual or trusted diesel mechanic. While your owner’s manual can provide you with general guidelines for when your diesel truck needs maintenance, your local diesel mechanic can often give you more specific details. That’s because they will have a better understanding of factors such as your climate and typical driving conditions that can significantly impact when service should be completed.


Beyond that, it’s important to recognize other signs and symptoms that could indicate a problem with your vehicle.

Your diesel truck needs maintenance if you notice:

  • Slow acceleration even when the gas pedal is fully depressed
  • Reduced engine power
  • An engine that steams, sputters, or stalls
  • Strange smells or sounds being emitted by the engine
  • Evidence of leaking fluid underneath your truck


A foreign smell or sound might make you call your local diesel repair shop as soon as possible. But other symptoms, such as reduced power or slow acceleration, could be easy to ignore. If you don’t think it’s an urgent problem, you might be tempted to delay a visit to your diesel mechanic. It’s important to remember, however, that any of these signs and symptoms indicate that your diesel truck needs maintenance now … not later. If you wait too long to schedule service, individual parts may break, vehicle performance may become impaired, and the engine may experience a build-up of debris inside.
