Diesel is less dense than DEF, so it will float on the DEF. The DEF tank should be drained and thoroughly cleaned with deionized water before refilling. DEF is very easily contaminated—just one teaspoon of a foreign substance will contaminate an entire tanker load of DEF.
How do you clean a contaminated DEF tank?
There is no way to clean out the drum after the Diesel Exhaust Fluid has been contaminated without compromising the integrity of any remaining product. Drums are the easiest to get contaminated, simply because anyone can open and close them. Drums are one way systems, and should be thrown out after each use.
How do you dissolve DEF crystals?
Premium Member. The crystals dissolve almost instantly with water. You may want to use distilled water for cleaning that spill cup. Then if any leaks into the tank it won't be a big deal.May 2, 2016
Can DEF fluid crystallized?
Yes, DEF can crystallize in the tank if it is low and left sitting.
How do you clean a DEF tank?
If you spill a small amount of Diesel Exhaust Fluid (DEF), it can be washed away with water or wiped up. If you leave it to dry it will turn into white crystals. These can be washed away with water. If you spill a large amount of DEF then contact your DEF supplier for advice.
How do you clean a DEF container?
DEF jugs and containers are one-time use vessels. Period. They need to either be thrown away, recycled or replaced. They cannot be cleaned using chemicals or products such as nitrogen fertilizer, and the one safe exception deionized water (DI water) is not advised.Nov 6, 2018
Is there a DEF system cleaner?
Dura Lube DEF Reducer is a combustion fuel catalyst that allows the fuel to burn clean and efficiently with minimal soot and contamination. This drastically reduces the need for regenerative burn cycles that lead to downtime and other excessive costs. DIRECTIONS: Treats up to 40 gallons of Diesel Fuel.
How do you keep DEF fluid from Crystalizing?
How do you prevent "DEF creep"? Make sure all fittings that come in contact with DEF are tight and proper seals are used. Try minimizing breaking connections and wipe down any urea crystallization as soon as it forms. Water can be used to easily wash off urea that has crept onto the truck, tank or dispensing equipment.
Can you replace DEF fluid with water?
Subject: RE: Anyone replace DEF with water? Water won't hurt the system but it will de-rate you pretty quick. ECM compares NOx values pre/post, if conversion is low it will start throwing codes and will eventually derate.Apr 4, 2016
What breaks down DEF fluid?
Diesel Exhaust Fluid (DEF) uses automotive-grade urea which has a much higher purity than fertilizer urea. Using a lower-quality fertilizer urea will cause degradation of the Selective Catalytic Reduction (SCR) system, eventually causing the truck to break down.
How do you keep DEF fluid from freezing?
Storing your truck in a heated or insulated garage during cold periods can help prevent your DEF from freezing. Likewise, an insulated tote blanket can help prevent freezing.
What do I do if I put DEF in my gas tank?
If DEF is accidentally put into the fuel tank, you MUST call for service immediately! Do NOT start the engine. The truck should be looked at immediately by a certified mechanic if you believe DEF has been added to the fuel tank. Starting the engine could result in MAJOR repair costs.
What can you substitute for DEF?
DEF is urea or otherwise known as aqueous ammonia. Windshield washer fluid that contains ammonia will do in a pinch.
What causes DEF pump failure?
Dirt / Metal Contamination: Contaminated DEF can cause abrasion of the DEF pump. Dirt, rust or tank scale can occur with improper of DEF storage or handling (e.g. res-using disposable DEF containers). UREA Concentration (Dilution): Diluted DEF (too much water) reduces its NOx neutralization effectiveness.
How do you get rid of contaminated DEF fluid?
What should I do if I spill DEF? If DEF is spilled, contain the spilled liquid and absorb it with an inert, non-combustible absorbent material, such as sand. Shovel the material into a suitable container for disposal. Spills into a drain should be avoided.May 7, 2014
What cleans up DEF fluid?
If you spill a small amount of Diesel Exhaust Fluid (DEF), it can be washed away with water or wiped up. If you leave it to dry it will turn into white crystals. These can be washed away with water.
Why does DEF fluid crystallize?
DEF crystallizes when stored for prolonged periods as the water evaporates. At that point, the tank should accept one full 2.5 gallon container of DEF. There is no need to continuously top off the DEF tank. Use the filler tube supplied with the case to avoid spills or splashes.
How do you clean DEF fluid residue?
According to Brad Williamson, manager, Engine and Component Marketing, Daimler Trucks North America, handling DEF is pretty straightforward: store it in its original container; handle it with gloves; and, if spilled, clean it up with soapy water.
Can you reuse DEF containers?
DEF is corrosive to aluminum, so containers made from stainless steel, polypropylene, and high-density polyethylene are preferable options. It is not recommended to reuse DEF containers, due to potential fluid contamination.
Can you use urine instead of DEF?
The urea found in urine is not in the proper concentration needed for DEF, nor is it of a sufficient level of purity, in either urea or water. The bottom line, to spell it out just one more time… urine and DEF = Never. DON'T PEE IN YOUR DEF TANK!
What neutralizes DEF fluid?
If you're thinking, “Urea. But despite DEF earning the nickname “pig urine,” Diesel Exhaust Fluid is actually made of commercial-grade urea—synthetic ammonia and carbon. So, to simplify things: the urea and water in DEF heat up, producing ammonia. This ammonia then breaks down and neutralizes the NOx gases.
Can you use distilled water instead of DEF?
Indeed. Do not run anything but DEF. Sensors will know the water isn't scrubbing NOx and put you in limp mode , then a complete flush of system will be in order.
How much does it cost to replace a DEF pump?
Diesel Injection Pump Replacement Cost - RepairPal Estimate. Labor costs are estimated between $480 and $605 while parts are priced between $1,247 and $1,723. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Can you use water instead of DEF?
If you remove the urea from the DEF -- that is, if you run water through the injectors instead -- it probably won't hurt anything, since you're reducing the level and quantity of corrosive reactants inside the stainless steel SCR system.
Can I use water in DEF tank?
Registered. If you put water in an EMPTY DEF tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate NOX (Oxides of Nitrogen) via the SCR (Selective Catalytic Reducer).Oct 4, 2012
