REPAIR INSTRUCTIONS, PART 1
EGR Cooler Cleaning
Prolonged idling can cause carbon buildup and
blockage in the core and should be avoided.
Although there are no prescribed service
intervals for cleaning the EGR cooler, it should be
cleaned whenever it becomes restricted.
Driveability concerns and logged faults in the
V-MAC IV would be evidence of this type of
restriction (e.g., the code appears for EGR High
Temperature).
The EGR cooler cannot be disassembled and
reconditioned.
