DD13 EGR COOLER CLEANING PROCEDURE TO REMOVE EXCESS FUEL FROM COOLER AFTER
ENGINE BRAKE SOLENOID FAILURE
Check as follows:
NOTICE:
This procedure must be followed after replacing an engine
brake solenoid due to any failure that could cause high DOC
temperature codes, excessive fuel, oil, or coolant to enter the
exhaust system. Failure to perform this procedure could cause
severe engine damage.
1. Remove the marmon clamps (2) and EGR hot pipe (3) and inspect for any signs of liquid
or moisture. The EGR hot pipe (exhaust pipe) and EGR cooler inlet (1) should have
a black dry soot residue inside.
[a] If liquid or moisture is present in the pipe, go to the next step.
[b] If there is no sign of liquid or moisture in the pipe or EGR cooler (1), install the
hot pipe. No further action is required.
All information subject to change without notice.
