Top 5 Maintenance Tasks to Keep Your Diesel Truck in Top Condition

No matter the make or model of your vehicle, maintenance is a fundamental element of responsible ownership. However, diesel truck owners and drivers know diesel maintenance differs from gasoline-powered vehicle maintenance. 

For starters, diesel vehicles do not utilize the same electrical parts in the ignition as gasoline vehicles. At the same time, diesel engines do not have as many movable parts, such as the distributor rotors, that can wear down. These key variances can make it more cost-efficient for diesel engine maintenance. 

Let’s explore some of the top diesel maintenance items you should have to protect your truck and diesel vehicles and ensure their longevity.

1. Oil Changes

Neglecting oil and oil filter changes in a gasoline-powered vehicle can lead to premature engine aging. But for a diesel-powered truck engine, it equates to destruction. Old and dirty oil can clog the engine, causing excessive friction and heat. 

The frequency of diesel engine maintenance service will greatly depend on your manufacturer’s suggested intervals and how you use the truck. And if you need personalized suggestions and guidance, contact the Consolidated Truck Parts & Service experts in Many, LA.

Change Oil Every 7,500 - 10,000 Miles for Regular Diesel Use

If you use your diesel truck under “normal” or light operating conditions, it’s suggested to have maintenance service every 7,500 to 10,000 miles or every 6 to 12 months. This interval is perfect for normal use and newer diesel engines with high-quality synthetic oils and advanced filtration systems.

Change Oil Every 3,000 to 5,000 for Severe Driving Conditions

You operate in severe driving conditions if you drive in dusty environments, tow heavy loads, or frequently travel in stop-and-go traffic. These conditions are notorious for expediting engine wear. 

As such, it’s best to have frequent oil changes and truck maintenance. Most manufacturers suggest having an oil change for diesel engine maintenance every 3,000 to 5,000 miles.

2. Glow Plug Inspections

Proper functioning glow plugs are vital for the health and optimal performance of your truck’s diesel engine. Glow plugs must generate sufficient heat for a successful ignition. It is essential to regularly inspect and maintain your glow plugs, particularly during the winter months when cold temperatures can affect their performance.

3. Monitor Gasket

Diesel truck gaskets are under immense pressure and operate under extreme conditions. As such, your gaskets should be monitored closely. All mounting bolts should be regularly inspected to avoid leaks and other complications. 

If your diesel mechanic does spot a leak, it’s best to replace all gaskets. Why? Because if one gasket is leaking, it’s most likely the others are not too far behind.

4. Clean the Engine

Anytime dirt collects on your engine’s components, it can decrease fuel efficiency and shorten its lifespan. More so, if you live in an area with harsher winters that use road salt, your engine may be more subject to rusting and corrosion. 

Because of this, you must clean your engine. If you want to DIY, consult the owner’s manual before starting. You will most likely need a specialized degreaser, an old toothbrush, and a moist sponge to get started.

5. Engine Air Filter Service

Air filters safeguard your diesel engine from harmful particles and debris. The primary function of air filters is to prevent dangerous particles and debris from reaching sensitive engine components that must remain free from dirt and contaminants. 

However, a dirty and clogged air filter can lose the ability to perform, allowing harmful particles to pass through.

Depending on the driving environment, you may need to change your air filter more frequently to maintain optimal filtration. It’s important to note that attempting to clean and reuse a filter can diminish its effectiveness. Thus, always ensure you use a new air filter to maintain the highest level of filtration and engine protection.
