Kansas City Diesel Exhaust Fluid

Has your Diesel Exhaust Fluid (DEF) light come on and you don’t know what to do? DEF issues can be complicated and require special tools to service. Luckily, the auto mechanics of I-70 Auto Service of Kansas City have the tools, experience, and training to handle your Diesel Exhaust Fluid troubles.

Diesel Exhaust Fluid is a smelly mixture of 32.5% urea and 67.5% deionized water. The solution is sprayed into the Selective Catalytic Reduction (SCR) system of diesel vehicles to reduce dangerous emissions into the atmosphere. When operating correctly, the SCR manages the flow of DEF into the exhaust system and alerts the driver to issues with the SCR via dash light.

The SCR is also designed to ensure that a vehicle will start and operate correctly if the diesel exhaust fluid freezes, which is vital in our frigid Kansas City winters. DEF freezes when temperatures drop below 12ºF, causing the DEF to crystallize, which may also cause the DEF light to come on. The SCR is designed to keep DEF from freezing and, if freezing does occur, will de-thaw the system while the vehicle is idling.

If the DEF light comes on and your DEF tank is full, this could indicate a problem. If this happens, it is possible that DEF fluid has crystallized in the lines, causing them to clog and restrict flow, or it may indicate another malfunction in the SCR.
