Exhaust & Aftertreatment
DEF will freeze at approximately 11° F. In order to keep DEF from freezing all tanks will be heated with engine coolant.
The following schematic shows the routing of these lines. The coolant lines that run to and from the SCR system must not
be tampered with, or used for a source of heat and/or cooling for other components on the chassis. It is critical that the
system is not compromised in any manner.
