DEF Service and Repair

If you have a diesel truck, you need to know about a critical additive, called Diesel Exhaust Fluid (DEF). It is also called AUS 32 or aqueous urea solution 32% and includes 32.5% urea and 67.5% de-ionized water. DEF is used to devide NOx emissions into less impacting water and nitrogen.

In 2010 the Environmental Protection Agency mandated the use of selective catalytic reduction in diesel engines, so diesel truck drivers had a difficult moment to go through.

We recognize that DEF service is about more than just fixing the equipment. At "Tacoma Truck Repair Center", our specialists offer a superior customer experience for complete satisfaction. We are always ready to handle your DEF repair and DEF maintenance needs, for example, if you just fill the DEF tank but still getting the service DEF system error code on the dash.

From 2010, diesel trucks and equipment are required to have an additional diesel exhaust fluid tank. So, it helps heavy-duty diesel trucks operate within the federal emissions guidelines. At "Tacoma Truck Repair Center", our qualified technicians will monitor your tank to ensure you never run out of fuel, guide you on how and where to store it, fix applications on your vehicle.

How To Understand If a DEF Fluid Is Bad

The easiest way to determine a bad DEF for trucks is to examine it. The fluid is contaminated or aged if it looks cloudy or colored, as it is naturally bright. It will be easy to notice pollutants, including small particles, larger rocks, or dirt. Don't try to use the DEF, if it is not bright.

How Often to Add DEF For Trucks

  • 2.5 gallons of DEF is approximately for 800 miles
  • 1 gallon of DEF is for about 300 to 500 miles

But don’t allow DEF to go completely dry.

If You Run Out of DEF For Trucks, What Happens?

If you have a new vehicle that is equipped with gauges, they will alert you when DEF is low. If you don't replace DEF, and engine speed will be reduced to as little as five miles per hour, so you will notice an emergency light.

To be prepared for such situations - not to get on the shoulder of the highway, carry a bottle in your vehicle. Diesel exhaust fluid is nontoxic, so you can easily replace it, as needed.

What Are The Common DEF System Problems

Diesel Exhaust Fluid quality can be affected by:

  • UREA Concentration - NOx neutralization effectiveness is reduced by diluted DEF.
  • Dirt / Metal Contamination - abrasion of the DEF pump can lead to contaminated DEF.
  • Crystallization occurs in such situations – over-dosing and hard water top ups. If you add too much DEF to the system – it can lead to crystalized deposits in the exhaust or injector nozzle. Over-dosing can result from a partially open DEF injector nozzle, plugged DEF lines or DEF pump issues. Adding water to the system can also result in scale or deposits forming.
  • Cold Weather - DEF may freeze in colder climates preventing engine operation. Don't use additives to thaw DEF because they can throw off the concentration of the fluid.

How To Avoid DEF System Problems in Tacoma

  • Keep temperatures between 40 and 80 degrees to store DEF containers for maximum shelf life. DEF can last for up to two years, if you store them properly.
  • Heat or cold can't damage your DEF system because if not to expose to excessive heat, DEF doesn't dissolve in heat or freeze in your vehicle.
  • Find a reputable source like at "Tacoma Truck Repair Center", because DEF has precise industry requirements. There are many unlicensed sellers who try to skirt regulations.
  • Try to buy DEF that is effective and safe; don’t be fooled by market-cutting low prices.
  • Take a gallon in your diesel truck, so you never get stuck.
