Keep Your Diesel Truck Breathing Easy in November

Did you know it only roughly eight ounces of dirt to destroy a diesel truck engine? This fact underscores the importance of filtration systems, which means putting off checking, cleaning and replacing your filter sets you up for potentially bad scenario.

November marks a significant transition to colder weather, so now is the time to go over some important details about air filtration and ensure air quality and engine health keep your truck in great shape.

Many diesel truck components are impacted by dirt, including these:

  • Cooling system
  • Turbocharger
  • Rings
  • Pistons
  • Fuel injectors
  • Mass airflow sensor
  • Intake manifold


While the overall performance of the engine will suffer, drivers also notice fuel economy taking a nosedive. You might also notice your diesel truck failing to start as smoothly as it once did, as well as hear various noises coming from the engine, like popping sounds. Excess vibration is also a symptom of a truck with bad filtration. Finally, if you have black smoke or even flames coming out of your exhaust pipes, this is a clear sign your filtration system has failed.

Cleaning Your Filter

You can save money by using the right filter cleaner and clearing your filter of dirt. First, ensure the filter is worth cleaning by looking for damage in the interior and exterior of the filter. Be careful as you remove the filter from its housing that you don’t knock off loose contaminants back into the housing.

Next, use a brush or cloth to release contaminants. You can also use a soft-bristled attachment on a vacuum cleaner to pull off the dirt.

What does your filter’s manufacturer say about using water to clean it? Most oiled filters will not recommend using water, however, you can soak a dry filter in water, which should free it of dirt. Rinse it thoroughly to get rid of any soap residue. When the filter is completely dry, you can reinstall it.

When should you replace your filtration system? Most are good for 10,000 to 15,000 miles, but if you drive a lot of dirt or gravel roads, you should be much more mindful of filter maintenance and more frequent replacement.

Cabin Filters Matter, Too

It’s important to be mindful of your diesel truck maintenance in the month of November, as bitter cold months ahead are known for a higher concentration of particulate entering the cabin, which also has an air filter, some of which can filter particulate as small as a micron. Most particulate eliminating from diesel trucks range from 2 microns to 10 microns.
