Information:
Use this procedure in order to troubleshoot low engine coolant pressure. Also, use this procedure if the following event code is active.
Table 1
Event Code
CDL Description Conditions which Generate this Code System Response
E2112(1) Low Engine Coolant Pressure The engine coolant pressure is below the map-based trip point pressure for the programmed delay time. The code is logged.
E2112(2) Low Engine Coolant Pressure
E2112(3) Low Engine Coolant Pressure Probable Causes
Low coolant level
Damaged coolant lines
Radiator blockage
Blockage of the oil cooler heat exchanger
Engine coolant pump outlet pressure sensor
Jacket water coolant pumpRecommended Actions

Troubleshooting Test Steps Values Results
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.
E2112
Result: An associated code is present.
Repair: Troubleshoot any associated codes before continuing with this test.
Result: An E2112 code is present.
Proceed to the next step.
Result: No active codes
STOP

Repair: Repair or replace any damaged piping or boots.
If the problem is not resolved, proceed to the next step.
4. Inspect the Radiator for Blockage
A. Check the radiator for internal blockage.
B. Check the temperature difference between the inlet and the outlet of the radiator.
Blockage
Result: The radiator is OK.
Proceed to the next step.
Result: The radiator is NOT OK.
Repair: Clean the radiator or perform the necessary repairs.
If the problem is not resolved, proceed to the next step.
5. Check if the Oil Cooler has a Blockage
A. Inspect the inlet side of oil cooler for debris and blockage.
Blockage
Result: The oil cooler is OK.
Proceed to the next step.
Result: The oil cooler is NOT OK.
Repair: Clean the oil cooler or perform the necessary repairs.
If the problem is not resolved, proceed to the next step.
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.
