Diesel Engine Maintenance: Essential Tips for Commercial Truck Owners

As your team is making its way along the Ohio River to various work sites throughout the Queen City, it’s imperative that their vehicles are able to withstand the challenges that lie ahead. From towing heavy machinery to loading up with materials, equipment, and more, commercial trucks must be able to accomplish a lot, and you’re going to need some durable engines beneath their chiseled hoods to be able to keep up with the workload. Fortunately, diesel engines are up to the task. If your fleet of commercial trucks is equipped with diesel, you’ll want to care for them properly. When you’re in need of commercial truck service in Cincinnati, McCluskey Chevrolet has you covered, and we’re the absolute pros at maintaining and repairing these do-anything powerhouses.

Important Diesel Maintenance Services

Diesel engines are durable, efficient, and capable, making them the go-to engines on job sites across Hamilton County and beyond. They’re able to withstand daunting work, tow incredibly heavy loads, and offer you the reliability and quality you need for your business to thrive. This is why it’s so very important to maintain them properly so that you can continue to work confidently and check off items on your to-do list effortlessly. In addition to routine oil and filter changes, as any other engine requires, keeping up with the following services is a great place to start ensuring that your diesel engine is working as efficiently as possible.

Coolant Flushing

As your truck works its way through job sites across Cincinnati, various components will become dirty and unable to do their jobs as effectively, requiring them to be flushed and replaced regularly. This is the case for your coolant, which becomes acidic over time, causing corrosion in surrounding parts of its cooling system. Flushing out the old coolant and replacing it is something that needs to be on your regular maintenance checklist, as is ensuring that there’s enough coolant in your system so that your diesel engine doesn’t overheat while it’s working overtime on the job site.

Fuel Injector Inspection

As you’re well aware, diesel engines take a different type of fuel than traditional gasoline engines. This fuel happens to be more viscous than gasoline, which means that it’s more likely to collect dirt, thus clogging up your fuel injectors. When your fuel injectors are clogged, this can cause your engine to sputter or completely stop, as it’s not getting the right amount of fuel to operate effectively. Regular oil, oil filter, and fuel filter changes can help prevent this, as well as diesel additives that you can include in your regular maintenance practice. It’s important to inspect your fuel injectors regularly because performance will begin to suffer if they become clogged.

Water Separator Cleaning

In addition to ensuring that you’re putting high-quality diesel fuel into your truck, you’ll also want to make sure that its water separator is emptied often so that the fuel stays clean. The water separator filters out water and other debris from the diesel fuel before it even gets to the engine, which allows your truck to run at its peak. Over time, this reservoir gets filled with water and will need to be drained so that it can collect more. Failing to empty the water separator results in more water and contaminants entering your engine, causing corrosion and causing your engine parts to wear rapidly.

Common Diesel Engine Repairs

We see our fair share of diesels for routine maintenance, and there are common repairs that we perform as well. You want to ensure that you’re traveling down I-71 on your way to a job in a truck that you can depend on because if something is amiss, it can wreak havoc on your schedule. Here are some of the issues we see most often.

Glow Plug Replacement

Diesel engines don’t have spark plugs like a gasoline engine. Instead, they have glow plugs, which warm up the combustion chambers before the engine starts to ensure ignition. Over time, these will need to be replaced. A telltale sign of glow plug problems is an engine that is difficult to start. You may also notice more exhaust smoke than usual. Glow plugs will typically need to be replaced at around the 80,000-mile mark or sooner if you notice any of these issues occurring.

Fuel Injector Issues

As we mentioned earlier, your fuel injectors can become clogged, especially if you’ve missed an oil change or need to replace your oil filter. This can cause black smoke to come out of your exhaust, decreased efficiency or performance, hard starting, and rough idling. If you notice any of these problems, you’ll want to check your fuel injectors.

Fuel System Problems

Sputtering, misfiring, or difficulties with starting your engine can all mean that your fuel system is unable to move the diesel fuel through your engine effectively. This could mean anything from a clogged fuel filter to a bad pump, which is why it’s imperative to have this checked by a professional. After all, your engine needs fuel in order to run, so if there’s a problem with fuel delivery, you’re not going to be able to complete your jobs around Cincinnati effectively.

Benefits of Regular Diesel Engine Maintenance

Every commercial truck owner knows that regular maintenance will keep your work truck running properly so that you can get more jobs done without issue and confidently cruise past Mount Adams in a truck you can trust. When you keep up with regular diesel maintenance, you’ll be able to get more done without having to worry about your truck being out of commission for a lengthy amount of time as your mechanic is repairing it. You will also save money by addressing small issues before they erupt into big problems down the road. Ignoring a small problem can end up being an expensive repair the longer you put it off. Do yourself a favor and make sure to listen to your truck and take it in for service if you notice something isn’t quite right.

It’s a great feeling to be able to rely on your diesel truck. By keeping up with routine maintenance, you can expect optimal performance and efficiency from your truck, allowing you to effectively take on your Cincinnati travels and work tasks. Maintaining your diesel engine will also keep you safe on the road, reducing the chances of engine failure on I-471, which can cause an accident.

Ensuring Peak Diesel Performance

As you can see, diesel engines require their own unique set of maintenance services. However, by properly maintaining your diesel, you can ensure unmatched capabilities and performance during any task you attempt. This is why diesels are the tried-and-true engines for Cincinnati commercial truck owners, as they’re able to complete the work that other trucks simply can’t.
