If you own a vehicle or plan to own one, a diesel vehicle is ideal if you want to prioritize power and overall efficiency. It’s also suitable if you routinely make lengthy, high-speed excursions out of town. Not only that, due to the increasing gas prices, having a diesel vehicle may be an advantage due to the fuel economy it brings.
Another advantage of using a diesel engine-powered vehicle is that it can function optimally for years when given routine maintenance. In most cases, it’s unlikely to experience downtime or problem points now and then. But sadly, like all other machines, if the time comes when you start to experience issues with your vehicle’s diesel engine, it’ll undoubtedly result in diminished power and efficiency. Due to this, expect periods of downtime, which can be bothersome if you need to be on the road most of the time.
Various reasons can bring about issues with your vehicle’s diesel engine. If you don’t want to make matters worse, identifying the root issue and timely delivery of repairs will minimize downtime. Although repairs will significantly help, there are instances when you need replacement parts for your diesel engine. If you want to find more information, several reliable sources are available online for diesel engine replacement parts.
Some of the usual diesel engine problems you’ll likely encounter over the years will require appropriate measures to get your vehicle back on track. Here are some of its common issues and ways to fix them.
1.Overheating Of The Engine
One of the common issues with a diesel engine is the likelihood of overheating. In most cases, it’s typically due to overburdening or overusing the engine itself. Sadly, it can bring about an array of detrimental effects, such as distortion or breakage of the cylinder, expansion of the pistons, and damage to the bearings, to name a few.†
When your engine is overheating, your initial task is to check the coolant level. A low coolant level allows air bubbles to form in the air-cooling system, negatively diminishing the coolant flow. If the levels are low, replenish the coolant level.
If the cause of your overheating is more complex, getting in touch with a professional is worth considering to ensure proper repairs.
2.Loud Noise From The Engine
If you compare diesel engines with gasoline engines, diesel models are more likely to produce high noise levelsóthat’s just the truth about diesel engine cars. However, it shouldn’t reach a point where it’s excessively loud or accompanied by unusual sounds like a gurgling engine.†
If you notice that your diesel engine is producing noises that are no longer normal, it may be a problem with the fuel system. Essentially, the fuel injectors might require a thorough cleaning job, or there might be a blockage. You can save on costs if you can do the checking and repair yourself. But for a more thorough check and repair, hiring the services of a skilled and knowledgeable mechanic is best.
3.Defective Glow Plugs
A glow plug in a diesel engine works by preheating the engine cylinders to ensure efficient fuel combustion. Generally, they play a crucial role in providing warmth to engine cylinders during cold conditions, especially in winter.
Once it ends up with damage, it can negatively affect your vehicle’s performance, resulting from engine failure. When you have defective glow plugs, expect misfiring of the engine and difficulty starting your car.†
Remember that all diesel engines are equipped with glow plugs since they play a vital role in starting and operating the engine. It may be best to have a professional thoroughly inspect your vehicle if you sense the glow plugs are faltering or if any other warning signs are present.
4.Faulty Diesel Injectors
In a diesel engine, the fuel injection system is one of the crucial elements to pay close attention to. The fuel injectors enhance fuel efficiency, cut down the number of pollutants, and reduce the frequency of maintenance.†††
A standard injector system comprises the injector body and nozzles with a lifespan of up to 100,000 miles. When the time comes when either of the two components starts to malfunction or develop blockages, it can compromise your vehicle’s functionality.
Some indicative signs of a problem with the injectors include difficulty starting your vehicle, misfiring when starting your car, discharge of contaminated emissions, and a significant drop in fuel economy, to name a few. Once you notice any of these issues becoming more frequent, immediately schedule a professional inspection of your vehicle.
The diesel engines in every vehicle are unique, and with this in mind, there’s no one-size-fits-all solution every time you face an issue stemming from the engine. If you experience an issue with your vehicle, make it a priority to determine the root cause and take the appropriate measures. Knowing about these common diesel engine problems will go a long way in helping you figure out if you have issues with your vehicle. Timely repairs will ensure your vehicle gets back on track in no time.
