If you have a diesel vehicle, then it’s possible that you may run into DEF problems in the future.

Protect and prepare yourself by reading the guide below on DEF fluid troubles. From explaining the DEF mechanism to troubleshooting the most common problems, we can help you prevent any future problems that you may incur.

Diesel Exhaust Fluid Troubles

Use this guide to manage and treat diesel exhaust fluid troubles.

What is DEF?

Diesel Exhaust Fluid (DEF) is a solution made up of 32.5% urea and 67.5% de-ionized water that is added to a tank separate from the diesel fuel tank.

It is added to diesel vehicles to help them break down harmful emissions into nitrogen and water, through a Selective Catalytic Reduction system.

Due to EPA regulations, vehicle manufacturers have had DEF measurements in place for diesel vehicles since 2010, to help protect the environment and achieve fuel savings for drivers.

When to Add DEF

Make sure you pay attention to the alerts that arise on your dashboard. If a low DEF warning appears, make sure you add fluid as soon as possible.

When the DEF level drops below 10%, an amber warning will appear. At 5%, it will start flashing. If it falls below 2.5%, the engine power will be reduced and the vehicle speed will be stuck at 5 mph until you refill the DEF tank.

To prevent that mess, make sure you fulfill preventative care of your DEF tank and fill up as needed.

Common Mistakes & How to Fix Them

Of course, mistakes can occur when you’re taking care of a vehicle. Educate yourself and make sure you stay on top of preventing mistakes to help you survive future problems.

The top 3 DEF troubles arise from:

1. Putting DEF into Your Diesel Tank

Since DEF is made up of urea and water, putting it into your diesel tank can cause serious problems. That liquid combination can cause engine problems like causing fuel injector tips to explode or cause immediate cooling.

If you made this mistake, follow this protocol:

  • Shut off the engine and contact your engine service provider.
  • Drain the diesel tank and dispose of the fuel.
  • Drain the diesel fuel conditioning module.
  • Flush the fuel system.
  • Replace all filters.

2. Ignoring the Warning Signals for DEF

Again, if you ignored the warning signals for DEF that meant it was time for you add fluid, you will be in trouble.

Warnings traject from Exhaust Fluid Range to Exhaust Fluid Low-Speed-Limited Soon to Exhaust Fluid Empty-Refill Now. Each warning is important as it denotes when it is time to refill.

If you missed these warnings, your car will be limited to 5 mph so make sure you fill up immediately.

3. Putting Contaminated DEF into the System

Contaminated DEF can also create problems, most likely resulting from improper storage.

Symptoms of fuel contamination include:

  • an engine cranking, but won’t start
  • engine runs rough
  • low power
  • engine knocking
  • exhaust smoke
  • FRP slow to build

Contaminated DEF can cause severe damage to the fuel system, so the most recommended repair is to replace the entire fuel system, which can be a very expensive.

What are the Health Qualifications for CDL Truck Drivers?

Health Qualifications for CDL Truck Drivers

Driving trucks may not be for everyone. But you, after months, or perhaps years, of saving for truck driving school, are sure that driving trucks is what you want to do with your life right now.

Unfortunately, however, your desire to drive trucks won’t be enough to guarantee that you’ll land a job as a truck driver. As it turns out, there is a whole host of health qualifications that you must meet before you are allowed to get behind the wheel of a truck, and for good reason.

So what are these health qualifications?

Follow along as we briefly cover the basics.

Physical Capabilities

There is nothing unexpected about the physical requirements for being a truck driver. Simply put, you need to have a full set of fully functional limbs, no impairments that affect your ability to grip objects, the ability to see well enough to drive, and good hearing.

Keep in mind that you will be tested for most of these things.

Diseases & Disorders

Unsurprisingly enough, most jobs require that you are not too ill to perform the duties that are expected of you on the job, and this job is no exception. Though some of the following requirements may not seem entirely reasonable or fair, there are, in fact, good reasons for imposing such rules on aspiring truck drivers:

Though some of the following requirements may not seem entirely reasonable or fair, there are, in fact, good reasons for imposing such rules on aspiring truck drivers:

  • If you are diabetic and rely on insulin to manage your condition, you are not currently eligible to become a truck driver, primarily because insulin can have serious side effects that affect people’s ability to operate vehicles.
  • If you have a respiratory problem that could possibly impair your driving, you are not allowed to become a truck driver. Your medical examiner will determine whether or not your respiratory issues are too serious to take on the work.
  • People with high blood pressure are also weeded out of the pool of candidates.
  • Joint or muscular problems such as arthritis are not acceptable since they can affect your ability to drive.
  • Candidates with some form of heart disease are perceived to be dangerous on the road due to the fact that their heart conditions could lead to crashes.
  • If you have a psychiatric disorder or anxiety, you’re not permitted to become a truck driver. There are also other mental conditions that will disqualify you.
  • You can’t have epilepsy or any similar condition which might affect your driving.

Drug Use

The expectations for drug use are standard, so you probably already have some idea about the substances that will affect your ability to become a truck driver. That said, we’ll quickly touch on what those substances are and how you are permitted to use them.

As you no doubt know, you are not allowed, under any circumstances, to use illegal substances, and this stipulation holds for any job that you apply for.

The rules surrounding the use of legal substances such as prescription drugs, however, are a bit more complicated. While you may use legal substances, the catch is that those drugs cannot affect your mental and physical capabilities. You are usually required to get the opinion of a medical examiner before you are cleared to work while you are taking certain drugs.

You are also allowed to consume alcohol during your free time, but you cannot currently be an alcoholic.

Conclusion

You should be aware of the fact that driving trucks can bring on certain health problems. Common concerns are bodily aches (especially back pain), sleep deprivation, and weight gain as a result of leading a sedentary lifestyle.

If you’re willing to take those risks, take a look at what CDL Truck Driver Training School has to offer aspiring truck drivers. After all, there is no reason to delay your dreams.
