Are You in Need of Diesel Truck Repair? A Closer Look

Diesel-powered vehicles are popular worldwide. This makes sense if you think about it.

Diesel engines are more fuel-efficient and have more low-end torque than other engines. This makes them ideal for use in trucks and large vehicles.

If you use a diesel engine, you expect them to work as hard as you do, and for the most part, the engines don’t let you down. Even though they are durable and tough, you may need diesel engine truck repair at some point.

It’s important to get to know the signs you are dealing with a broken truck or that you need truck repairs. Keep reading to learn what these signs are.

A Loss of Power

One of the main reasons diesel trucks require repairs is because of a loss of power. In most cases, this is caused by a problem with fuel delivery.

It is an issue that can occur if the fuel filter bowl isn’t drained on time. Another potential cause is if the main fuel filter is damaged or malfunctioning.

Overheating

If you have a diesel truck that starts running too hot, it can cause serious damage to the components in the engine and the body of the truck.

Several things cause the problem, but it is something you need to watch for and handle right away.

When your truck’s engine overheats, it’s a good idea to call for a professional repair service to find the issue and fix it.

Oxidized Oil

Some diesel trucks have issues related to oxidized oil. This occurs if the engine sits for long periods of time without being started.

If oxygen gets into the oil, it will create bubbles that impact the lubrication the oil should provide. Without proper lubrication from the oil, damage can occur to the various engine components, and repairs will be needed.

If your diesel truck has remained idle for a long time, it’s a good idea to change the oil before you use it again or start the engine.

Increased Fuel Consumption

Another indication that diesel truck repair is needed is if you notice an increase in total fuel consumption. If you have noticed that your truck will not go as far as it used to on a tank of gas or that you are stopping to refuel more often, you should schedule an inspection with a mechanic.

This problem will likely only get worse if you don’t seek repairs. In the end, it will cost you even more.

Contaminated Diesel Fuel

The viscosity of diesel fuel is much higher than gasoline. That means it is easier for diesel fuel to become contaminated compared to other fuel types.

Some of the contaminants you should watch for include:

  • Glycol
  • Dilution
  • Water
  • Soot

Catching the presence of these contaminants early will help you avoid expensive repairs. If you do find contaminants in the fuel tank, be sure to purge and clean it well.

If you don’t purge the tank, it can cause significant damage to the engine.

Oil Sludge

Oil sludge is grime and wasted oil that is mixed with the oil supply. Over time, the sludge can change the oil thickness.

If you discover oil sludge, it’s a sign that some of the engine components are not being lubricated properly. It’s a good idea to schedule engine service right away.

Blue Smoke

This is a sign of a problem you don’t want to ignore. The burning will cause blue smoke caused by an oil chamber overfilled, a serious oil leak, or worn cylinders.

Hard Starts

You should pay attention to how your diesel truck handles.

Have you noticed that the truck is suddenly lurching forward rather than accelerating gradually? If so, it’s a sign of a serious problem that needs to be addressed right away.

Black Exhaust

If your truck is producing black exhaust, it means there is something wrong. Usually, it is a sign that the air and fuel in the engine aren’t properly balanced.

In most cases, black smoke occurs if there is too much fuel and insufficient air present. It’s important to note that black exhaust smoke is full of all types of dangerous toxins and chemicals. This makes it a safety hazard and a nuisance to other people on the road.

However, excess black smoke may result in fines from the police.

Several components may cause black exhaust smoke. One is a broken or malfunctioning fuel pump. Another potential reason this occurs is due to clogged air filters that aren’t allowing the right amount of oxygen to get into the engine.

If the truck’s turbocharger has gone bad, this may produce black exhaust smoke too.

While it may be difficult to tell what color the exhaust smoke is while you are driving, you need to pay attention to any changes. If you put off repairs, it will only result in bigger, more expensive issues down the road.

Now You Know When to Seek Diesel Truck Repair

As you can see from the information above, there are several signs you need to seek diesel truck repair. Be sure to pay attention to any changes in your truck’s handling to ensure that you take action in a timely manner.

Seeking repairs from a professional mechanic will help mitigate the problem and ensure it does not get worse or cost more than it should to repair.
