Duramax Diesel Exhaust Fluid DEF Heater 12-16 Chevy Silverado GMC Sierra 2500 3500HD 6.6L. Diesel exhaust fluid reservoir is a reductant heater that enables the SCR (Selective Catalytic Reduction) to function at low temperatures. DEF freezes easily and needs to be melted in the shortest possible time for the SCR to reduce the amount of Nitrogen Oxides and release them into the exhaust system lowering the concentration of nitrogen oxide in the diesel emissions from the engine.

If your diesel vehicle is confined to a limited speed, or in power reduction mode, a common culprit may be a failed DEF heater. Our DEF heater includes all necessary components for a complete repair and quality tested for a trouble-free performance and longer service life.

Features:

  • Exact Fit for Easy Installation
  • Includes all necessary gaskets and O-rings needed for a complete replacement
  • Quality tested to ensure trouble-free installation, performance, and durability
  • Properly functioning DEF heaters are required in most states for vehicle inspection
  • High-quality plastic construction for added durability
