(03-19-2018 )serv Wrote: We recently had a truck losing coolant and found a coolant leaking into the exhaust in the after treatment system. I want to say it was at the def doser. It’s probably not hard to check. We found it by accident. We also found this while we were in there. No codes or check engine lights.

This is not a coolant. This is DEF drying before decomposition tube what they call "volcano"
Coolant will be brown/reddish in color.
Cummins has procedure for cleaning. If DPF/SCR soaked with coolant it need to replaced or mr Haggai is savior.
