This is to revise and replace ATC1873, dated 22-Feb-17. This revision is to:
1 Add a minor narrative change to the description and part sections.
If additional information is required, please contact your Cummins Warranty Operations Group Leader.
DESCRIPTION:
This ATC is being issued to address clearance issues with coolant hoses on ISL9 CM2350 and ISL G CM2180
engines in certain Gillig Buses. This document authorizes certified repair locations to replace the coolant supply line
connecting the oil cooler top connection to the back of the block, or the water pump inlet, or both. Please refer to the
ESN list for the required replacement parts for each ESN.
ACTION:
In order to qualify for repair under this field action, an engine:
1 will be covered Regardless of coverage status, and
2 must show as OPEN status on QuickServe® Online.
After verifying that the engine meets the above requirements, perform the following actions:
1 Compare the ESN of the engine being repaired against the ESN list, Attachment A, to determine if it is eligible
for hose replacement, water inlet replacement, or both.
NOTE: No replacement parts are covered under this field action. These parts are already at the customer
locations. If necessary, gaskets and O-rings may be claimed in this action.
2 If required, replace the water pump inlet elbow. Please refer to Procedure 008-082 in the appropriate Service
Manual.
3 If required, replace the coolant supply hose to the heat exchanger. Please refer to the first two steps of the
Remove Section and the last two steps of the Install Section of Procedure 008-053.
NOTE: It may be necessary to rotate the heat exchanger inlet fitting so that it is pointing directly vertical. This will allow
for more clearance to the chassis frame and ensure proper hose routing.
MATERIAL DISPOSITION:
Materials removed as a result of this field action must be scrapped.
