  • EPA regulations require all diesel engines manufactured on or after January 1, 2010 to meet lowered NOx emissions standards
  • Most heavy duty engine (Class 7-8 trucks) manufacturers, have chosen to utilize SCR
  • This Includes Detroit Diesel (DD13, DD15, and DD16 models), Cummins (ISX line), PACCAR, and Volvo/Mack
  • SCR-equipped engines require the periodic addition of Diesel Exhaust Fluid (DEF, a urea solution) to enable the process
  • DEF is available in a bottle from most truck stops, and some have installed bulk DEF dispensers near the Diesel Fuel pumps
  • However, to ensure the proper operation of the SCR system, operators must ensure the DEF in their vehicle consists of a 32.5% Urea/Water solution
  • The OTC 5025 makes this a simple and quick process for an operator or technician
  • Scale: 0.5% line graduations
  • 32.5% Indicated
  • Scale 15-40%
  • Waterline & 20 Degree C
