3 Common Repairs for Your Diesel Truck

Diesel trucks are the workhorses of the world. These strong diesel-powered machines pull heavy equipment and transport goods across the country with ease. Diesel trucks can also last an extremely long time. 


According to Porch Group Media, people now keep new and used vehicles for 60% longer than they did 10 years ago. Regular diesel truck service can help your truck last as long as possible, old or new.


1. Standard Maintenance


Maintaining your truck properly is crucial to prolonging its lifespan and avoiding costly repairs. Refer to your owner’s manual to determine when your vehicle needs an oil change. 


Diesel engines have some significant differences from gasoline engines. A good example of this is that diesel engines don’t have spark plugs. However, turbochargers and other additions need regular inspections. You’ll also need regular maintenance on your brake system, such as replacing the brake pads.


2. Diesel Engine Repairs For Winter


It’s common for diesel truck owners to head to the shop for diesel truck service before winter. Before winter weather arrives, check your tires and brakes for safety, just like you would with any other vehicle. If you’re a first-time diesel owner, it’s important to understand that fuel gelling is a common problem. 


Diesel fuel can turn into a gel-like substance when the temperature drops. Speak with a local mechanic to determine which additive would be best as a preventative method. Some people add heaters to their trucks to keep the fuel warm. Having your diesel truck serviced prior to the winter months is crucial to avoid mechanical issues in the future!


3. Common Problems


Every type of engine is prone to problems, including diesel engines. Here are a few things to keep an eye on with your diesel truck:


1.   Turbochargers spin at high speeds to pump air into your engine. This is an important part, but it often malfunctions over time because of wear and tear. Properly lubricating turbochargers can extend their lifespan.


2.   Fuel injectors are under more pressure and exposed to higher temperatures in diesel vehicles than gas-powered vehicles. The additional pressure and heat make them prone to wear and tear.

Sometimes, EGR valves that recirculate some exhaust fumes to reduce carbon emissions can become stuck closed. This results in a loss of power and more emissions.


Diesel engines are uniquely impressive. Manufacturers carefully craft them to provide you with the necessary power in a work truck. Working with a company offering reliable diesel truck service will ensure your vehicle lasts as long as possible.
