Tips To Make Diesel Trucks Last Longer

admin Uncategorized Leave a Comment

If you have a diesel truck or diesel vehicle and you want it to run for a long tie, you’re in the right place. In this guide from Walkers Plant Maintenance, we’ll discuss a few steps you can take to keep your diesel truck running for 30 years or longer. Follow these tips to protect engine components, maximise fuel efficiency, and make sure the diesel engines in your fleet run for as long as possible.

1. Change Engine Fuel Filters Regularly

The fuel system is one of the most important engine components, and is responsible for delivering diesel fuel to the engine. For proper fuel efficiency and long-lasting performance, make sure to change your engine fuel filter frequently.

If you do not switch the filter on a regular basis, the fuel can become contaminated with small particles that may clog up the fuel injection system, leading to poor performance, premature wear & tear, and decreased fuel economy.

Depending on how often you drive, and the conditions in which you drive a diesel truck, you will want to check and swap this filter every 15,000 to 40,000 km.

2. Remove Water From The Water Separator

Diesel oil and fuel absorb more water than gasoline, and this can cause damage to your fuel injectors and lead to premature wear & tear. To prevent this, most diesel trucks have a water separator, which helps separate and drain water before it reaches the engine.

It’s important to regularly check and drain the water separator. If it’s too full, it may allow more water to reach the engine through the diesel injector system, leading to a lower lifespan.

3. Check Fuel Injection Systems

You should usually check your diesel fuel injection systems every 80,000 km. If your vehicle is driven regularly for work, this can sneak up on you faster than you may think. Fuel injectors typically last between 80,000 and 160,000 km.

If you notice bad fuel economy or engine performance, it may be due to a failed injector, or an injector that’s been clogged by engine debris. Swapping the injectors ASAP is the best way to keep your engine running properly, avoid wear, and prolong the lifespan of your vehicle.

4. Warm Up The Engine When You Use The Truck

This is particularly important in cool weather. Short journeys in cool weather mean that the engine may not reach its full operating temperature, and the oil won’t be as effective at protecting engine components.

When you first turn on a diesel truck, avoid running it at high RPM. Drive gently until the engine has warmed up to its operating temperature, and do your best to avoid very short journeys that may not allow your oil to have enough time to warm up to the proper temperature.

5. Change The Engine Oil According To The “Severe Use” Schedule

You should usually be changing the engine oil and oil filter every 5,000 km. This is particularly true if you operate your diesel truck in very hot or cold conditions, or often drive in “stop-and-go” traffic.

In addition, idling is a significant source of wear & tear for diesel trucks. Even if your truck has not been driven 5,000 km, it may be a good idea to change the oil every 3 months if you frequently leave the vehicle idle for long periods of time.

Follow These Tips For A Longer Lifespan For Your Diesel Truck

Diesel engines last much longer than gasoline engines, so with proper care, you can use a diesel truck or another piece of heavy diesel machinery for decades.
