3342-1
Engine Coolant Pump Differential Pressure : Low - most severe (3) E1599 (3)
Low Engine Coolant Pump Differential Pressure The pressure differential across the water pump is lower than expected for the current engine operating conditions.
To clear an E1599 (3) code, the problem causing low-pressure differential across the pump must be fixed, the engine RPM must be raised above 1600 rpm for approximately two minutes (time may vary based on conditions).
3342-17
Engine Coolant Pump Differential Pressure : Low - least severe (1) E1599 (1)
Low Engine Coolant Pump Differential Pressure The pressure drop across the water pump is lower than expected for the current engine operating conditions.
3342-18
Engine Coolant Pump Differential Pressure : Low - moderate severity (2) E1599 (2)
Low Engine Coolant Pump Differential Pressure The pressure drop across the water pump is lower than expected for the current engine operating conditions.
5708-15
Engine Coolant Pressure #2 : High - least severe (1) E1601 (1)
High Engine Coolant Pump Intake Pressure The coolant system pressure is higher than expected for the current engine operating conditions.
5708-17
Engine Coolant Pressure #2 : Low - least severe (1) E1600 (1)
Low Engine Coolant Pump Intake Pressure The coolant system pressure is lower than expected for the current engine operating conditions.
To clear an E1600 (1) code, once cooling system pressure is released, the coolant temperature must be allowed to cool down. Pressure in the cooling system is built by fluid expansion due to the coolant heating. Allowing the coolant temperature to increase from 50° C (122° F) to 90° C (194° F) when the coolant is full will build more than 60 kPa (9 psi) of system pressure, which will clear the E1600 (1).

Troubleshooting Test Steps Values Results
1. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Look for active codes that are associated with the system for the event code.
Codes
Result: An associated code is active.
Troubleshoot any associated codes before continuing with this test.
Result: An E1600 (1) / 5708-15 code is active or logged.
Proceed to Test Step 2.
Result: A coolant pressure code that is not E1600 (1) / 5708-15 code is active or logged. Proceed to Test Step 3.
2. Verify that the Low Coolant Intake Pressure is Not Caused by Intentional Release of Cooling System Pressure
A. Check with customer to understand if cooling system pressure was released while the coolant temperature was still warm (radiator cap removed, hose disconnected, coolant system leaks, and more).
Note: An SOS coolant sample should be taken using the SOS coolant port, not by removing the radiator cap. Refer to machine OMM for procedure. Removing the radiator cap while coolant is hot allows the cooling system pressure to escape and will trigger the E1600 (1) code.
Once cooling system pressure is released, the coolant temperature must be allowed to cool down. Pressure in the cooling system is built by fluid expansion due to the coolant heating. Allowing the coolant temperature to increase from 50° C (122° F) to 90° C (194° F) when the coolant is full will build more than 60 kPa (9 psi) of system pressure, which will clear the E1600 (1) / 5708-15 code.
Cooling system pressure released while the coolant temperature was still warm
Result: The cooling system pressure was not released while the coolant temperature is still warm (radiator cap removed, hose disconnected, coolant system leaks, and more).
Proceed to Test Step 3.
Result: The cooling system pressure was released while the coolant temperature is warm (radiator cap removed, hose disconnected, coolant system leaks, and more).
Repair: Allow the engine coolant temperature to cool below 50° C (122° F). Fix any stream leaks, if applicable. With radiator cap installed, start engine and allow coolant temperature to increase to 90° C (194° F). When the pump inlet pressure remains above 60 kPa (9 psi) for longer than one minute, the E1600 (1) / 5708-15 code will clear.
Proceed to Test Step 13.
3. Verify the Coolant Level
A. Verify that the coolant is filled to the correct level.
If the coolant level is too low, air will get into the cooling system. Air in the cooling system will cause a reduction in coolant flow and pressure.
B. Check the cooling system for coolant leaks.
Coolant Level
Result: The coolant level is correct.
Proceed to Test Step 4.
Result: The coolant level is not correct.
Repair: Determine the cause of the low coolant level. Refer to Troubleshooting, "Coolant Level Is Low" for additional information.
Proceed to Test Step 13.
4. Check the Cooling System Hose Routing
A. Check the cooling system clamps and hoses to make sure that the clamps and hoses are installed in the proper location and the clamps are tight.
B. Ensure that there are no kinks or tight bends that may cause excessive restriction.
C. Check to make sure that the hoses are routed correctly.
Leaks or Kinks
Result: The coolant clamps and hoses are installed properly.
Proceed to Test Step 5.
Result: The coolant clamps and hoses are not installed properly.
