5 reasons why your truck may need a diesel mechanic
#1 Engine overheating
This is one of the biggest and most common issues that a diesel truck experiences. This issue is usually caused by operators of the vehicle pushing it past its limit which ends up either overheating the engine, distorting the cylinder heads, expanding the pistons or damaging the crankshaft.
Though overworking the engine is one of the most common reasons, overheating can also be caused by anything that interferes with the cooling system such as:
● Coolant leaks
● Clogged diesel injectors
● Faulty cooling fan
● Damaged thermostat
#2 Engine oil oxidation
A diesel truck, like any other vehicle, cannot be left for a long period of time without the operation of the engine. If this occurs, then air gets into the oil and creates bubbles which interfere with the lubrication ability. Many parts of an engine require lubrication to function properly. These air bubbles rupture the thin oil layers that provide lubrication and cause it to rust or experience friction. Over a short period of time, this will end up damaging the engine’s parts.
#3 Black exhaust
Black exhaust is not a problem, however, it certainly is a symptom of problems that should be identified. Bear in mind that usually, diesel trucks produce smoke that is darker than other vehicles, however, it should never be black.
If your vehicle produces black exhaust, then it's a sign that you may have a problem with your engine. This symptom can indicate that you may have a faulty injector pump or an issue with your injector, turbocharger, EGR valve or air filter.
Black exhaust can be extremely harmful to you and your employees if breathed in over a long period of time, so ensure that you get that fixed immediately.
#4 Contaminated fuel
Compared to gasoline, diesel has more viscosity, meaning that it can be more easily contaminated which paves the way for a number of problems. Diesel is commonly contaminated with water, soot and glycol. Contamination is not the end of the issue. These contaminants are very dangerous. If they enter the fuel pump or injector, your truck’s engine can experience a number of serious issues including engine disruption.
#5 Lack of power
Who would have thought robust diesel engines (they are more powerful than gasoline engines!) would have an issue with power? The power of diesel engines is one of the reasons why heavy vehicles and trucks for construction business use them, however, they can falter for a number of reasons. The lack of power is most noticeable when you start the engine or when accelerating and can be a result of the following issues.
● Dirty oil filters
● Malfunctioning fuel injectors
● Clogged fuel delivery lines
● Too much or not enough lubrication
● Loose throttle linkage
As you can see, the majority of these issues can be a result of poor or negligent maintenance which is why it is important to ensure that your vehicle is properly taken care of.
