This bulletin applies to 2013-2018 Ram 2500/3500 4500 vehicles equipped with a 6.7L Cummins Diesel engine where the DEF (diesel exhaust fluid) injector encounters freezing issues.

The warning light (MIL) may be on accompanied by diagnostic trouble code (DTC) P218F (reductant no flow detected) and/or P202E (diesel exhaust fluid reductant injector performance). Chrysler now offers a DEF insulator cover kit (thermal protective cover) that covers the DEF injector to reduce the chances of this concern. The kit is available as P/N 68564806AA.
