How Diesel Truck Service Differs From Standard Service

Updated: May 16

You might be wondering how getting your diesel truck serviced differs from standard vehicle maintenance. Diesel engines have some unique needs, and getting the right diesel truck service can extend the life of your truck. Here's a quick guide on what to expect.

The Types of Fluids

When you take your diesel pickup in for service, the shop will check and change several different fluids. This includes the engine oil, which needs to meet specifications for diesel trucks. The oil helps lubricate and cool critical components. Diesel truck service also involves replacing the fuel filters, which remove debris from the diesel fuel, as well as the transmission fluid. Technicians will also check your coolant or antifreeze. Making sure it's at the proper level and concentration is essential to prevent overheating. And don't forget the diesel exhaust fluid.

Unique Engine Components

Some parts of your diesel engine have special maintenance needs as well. For example, diesel truck service involves cleaning the particulate filter, which removes soot from the exhaust. The technician will also check the EGR valve, which helps lower NOx emissions by recirculating small amounts of exhaust gas back into the cylinders.

During service, checking the turbocharger is critical. This component helps boost power by forcing extra compressed air into the engine. Making sure the turbo fins are clean and that there are no oil leaks or play in the bearings helps this important part last.

The Service Schedule

When planning out your diesel truck service, follow the recommendations in your owner's manual. Most experts advise more frequent oil changes, somewhere between 5,000 to 8,000 miles, depending on driving conditions, versus 10,000 miles for standard vehicles. Fuel and air filters also need replacement about twice as often. Topping off the DEF tank should be part of your regular fill-up routine to keep your truck running at peak efficiency. Going to a shop that specializes in diesel engines for periodic service helps spot potential problems early too.

While diesel truck engines are known for their unmatched durability and torque, they still need special care and maintenance. Finding an experienced diesel technician you trust is key to keeping your truck on the road for years to come. According to IBISWorld, as of 2023, in the United States, there are 281,434 auto mechanic businesses in the U.S. as of 2023. Sticking to the recommended diesel truck service schedule helps avoid costly repairs down the line.
