If you own a diesel truck, you know those diesel engines are hard workers. A well-kept diesel engine is extremely dependable at times when we need them most. Even though they are dependable and tough, a diesel truck needs to be properly cared for to achieve optimal performance and longevity.
It is important to know what to look for when your truck may need repairs or some general TLC. Here are some signs that it’s time to have diesel mechanic perform an inspection before things spiral out of control and cost you valuable time and money.
Loss of Power
Loss of power can happen for a multitude of reasons, but fuel delivery tends to be one of the most common culprits. An easy way to avoid this is to make sure the fuel filter bowl is drained on schedule and to look for signs of a damaged or malfunctioning fuel filter.
Overheating
You don’t want to deal with overheating issues. These can often lead to much bigger and more expensive problems, including significant damage to the engine itself. There are many different causes to overheating so if you are not an experienced diesel mechanic, your best bet is to get your truck scheduled with us right away.
Oxidized Oil
Oxidized oil most commonly occurs when your truck is left dormant for long periods of time without being started or used. When oxygen gets into the oil it creates bubble that negatively impact the lubrication element that the oil is supposed to provide. Without proper lubrication, significant and costly damage to the engine can occur.
If your truck has remained idle for long periods of time, change the oil before starting it again.
Contaminated Diesel Fuel
Diesel fuel contains a high level of viscosity which also increases the chances of contamination. Common contaminates include Glycol, Dilution, Water, and Soot. If you notice any signs of contamination in the fuel tank, purge and clean it thoroughly. If you think there is a chance it may be contaminated but aren’t quite sure, bring it in to us immediately.
Oil Sludge
Oil “sludge” is grime and oil waste that is mixed in with the oil supply. It can sometimes be easily noticed by the change in thickness of your oil. If you notice oil sludge, it is an indication that your engine components are not being lubricated properly. This is another issue that is best to be addressed by an experienced diesel mechanic.
Blue Smoke
This is more of a severe issue so please don’t ignore it. This can be caused by an oil chamber that is over-filled, a serious oil leak, or worn cylinders.
Hard Starts
If you notice that your truck is lurching forward instead of accelerating gradually, this is another sign of a serious problem that needs to be addressed immediately.
Black Exhaust
Black exhaust usually occurs when air and fuel in the engine are not being properly balanced. It’s also important to note that black exhaust is usually full of dangerous toxins and chemicals, making it a danger to you and your family. And of course, excessive black smoke can also lead to a lot of attention from the Police.
Broken or malfunctioning fuel pumps can also cause black exhaust. Clogged air filters don’t allow the right amount of oxygen to get into the engine and can also cause black exhaust. This isn’t an issue that you should take lightly so give us a call if you notice this issue with your truck.
