Replacing PACCAR DEF Doser

PACCAR DEF Doser is failed. Here is my quick procedure for removal and replacement.
I used my access to PACCAR service diagnostic information to troubleshoot and determine failure of my Dosing Module. In some cases, you will need DAVIE service tool to clear fault codes and complete repair.

Hello,
If you don’t mind asking, what code you had that make you replace the doser? Also noticed that had coolant corrosion around the injector of the doser?
