Every day, our country’s diesel operators face challenges with their DEF systems that can lead to downtime and frustrating repeat fixes. While diesel exhaust fluid can handle quite a bit of wear and tear, it should still be monitored to keep your vehicle performance up.
Let’s look at three DEF-related issues that can cause headaches for operators. Don’t let these issues sideline your equipment when simple preventative measures can keep you running smoothly!
Problem #1: DEF Crystallization Is Killing Your Performance
Did you know that the urea in DEF can form solid crystals throughout your SCR system? That can spell trouble quickly.
The microscopic crystals can start blocking injectors, clogging pumps, and triggering dashboard warning lights that lead to reduced power modes.
NuDEF’s Diesel Exhaust Fluid Additive & Stabilizer is specifically engineered to prevent crystallization by maintaining optimal DEF chemistry. This simple addition with each fill-up provides continuous protection against one of the most common and costly DEF issues.
Tip: Temperature fluctuations accelerate crystal formation, so always store DEF in climate-controlled environments whenever possible.
Problem #2: Cold Weather Can Cause DEF to Freeze
DEF begins freezing at approximately 12°F (-11°C), creating serious operational challenges during the winter. But work can’t stop just because the temperatures have dropped.
Frozen DEF doesn’t just delay emissions control – it expands and can damage tanks, pumps, and lines, potentially leaving you stranded when you can least afford downtime.
NuDEF’s formula can lower DEF’s freezing point, which can help provide a higher level of protection during cold-weather operation.
Tip: Topping off your DEF tank at the end of each workday reduces condensation space and minimizes water accumulation that leads to freezing issues.
Problem #3: Contamination Can Happen Faster Than You Think
DEF must maintain a precise 32.5% urea concentration to function correctly. Even minor contamination – which can come from dirt, fuel, oil, or other chemicals – will compromise the quality of DEF and lead to a series of problems throughout your SCR system
NuDEF creates a defensive shield throughout your SCR system, helping guard against contaminants while maintaining optimal DEF performance. This added layer of protection is insurance against the inevitable exposure to environmental contaminants.
Tip: The area around your DEF fill cap is a contamination gateway. Always clean thoroughly before opening to prevent dirt and debris from entering the system.
NuDEF: One Product, Three Problems Solved
Adding NuDEF’s Diesel Exhaust Fluid Additive & Stabilizer into your maintenance routine provides comprehensive protection against all three common DEF headaches.
With one bottle treating up to 25 gallons of DEF, NuDEF delivers cost-effective insurance against the most common and expensive DEF-related problems. The consequences of ignoring these simple preventive measures simply aren’t worth the risk!
FAQs about Tips to Avoid Common Problems with Diesel Exhaust Fluid (DEF)
How can I tell if my DEF system is already experiencing problems?
Watch for warning signs, including increased DEF consumption, check engine lights, reduced power (limp mode), white crystalline deposits around fill areas, or error messages mentioning the SCR system. Don’t ignore these early indicators!
Is it too late to use NuDEF if I’m already having DEF-related issues?
Minor problems can often be resolved by adding NuDEF, which helps dissolve existing crystals and restore proper function. However, significant system damage may require professional service. Prevention is always more cost-effective than repair.
