SHIM (.015" Thick) 2D6361 - Caterpillar

Use this procedure in order to troubleshoot high coolant temperature or use this procedure if one of the following event codes is active. Refer to Troubleshooting, "Event Codes" for information about event codes. Access the engine monitoring system on Caterpillar Electronic Technician (ET) in order to view the current trip points for these codes. For information on the engine monitoring system, refer to Troubleshooting, "Engine Monitoring System".
Table 1
Event Code
Code and Description Conditions which Generate this Code System Response
E361(1) High Engine Coolant Temperature The engine coolant temperature is above the trip point temperature for the programmed delay time. The code is logged.
E361(2) High Engine Coolant Temperature The code is logged.
Engine power is derated.
E361(3) High Engine Coolant Temperature The code is logged.
The engine is shut down.
4193-0 Engine Coolant Pump Outlet Temperature : High - most severe (3) The engine coolant temperature is above the trip point temperature for the programmed delay time. This code is generated by the Temperature Control Module (TCM) (MID No. 094). The code is logged.
The TCM commands the valve to open fully. If the engine is shut down due to a high coolant temperature, the power to the ECM must be cycled before the engine is restarted.Probable Causes
Cooling system leaks
Heat Exchanger
Coolant temperature sensor and/or circuit
Faulty temperature regulator
Faulty coolant pumpRecommended Actions

Troubleshooting Test Step Value Result
1. Check for Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Determine if the diagnostic trouble code that directed to this procedure is present.
D. Look for active diagnostic codes that are associated with the system for the event code that directed to this procedure.
E361 or E4193
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: An E361 or E4193 code is present.
Proceed to the next step.
Result: No active codes
STOP
2. Low Coolant Level
A. Inspect the coolant level. If necessary, add coolant.
Level
Result: The coolant level is OK.
Proceed to the next step.
Result: The coolant level is NOT OK.
Repair: Add coolant. Check for leaks.
If the problem is not resolved, proceed to the next step.
3. Check the Cooling System for Leaks
A. Inspect the coolant for presence of bubbles.
Level
Result: No evidence of coolant leaks is discovered..
Proceed to the next step.
Result: Combustion gasses have been discovered in the cooling system..
Repair: Inspect the cylinder liners for cracks.
Perform any necessary repairs.
If the problem is not resolved, proceed to the next step.
2. Check the Heat Exchanger for Problems
A. Check the cooling fins on the heat exchanger for dirt and/or for debris.
B. Check for sufficient flow and temperature of the cooling water through the heat exchanger.
Heat Exchanger Result: The heat exchanger is OK.
Proceed to the next step.
Result: A problem with the heat exchanger has been discovered.
3. Check the Coolant Temperature Sensor and/or the Circuit
A. Check the reading of the coolant temperature on Caterpillar Electronic Technician (ET). The temperature should rise steadily as the engine is warmed. Ensure that the
