Troubleshooting Test Steps Values Results
1. 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.
C. Check the cooling system for combustion gases.
Coolant Level
Result: The coolant level is correct.
Proceed to Test Step 2.
Result: The coolant level is not correct or combustion gases are present.
Repair: Determine the cause of the low coolant level. Refer to Troubleshooting, "Coolant Level Is Low" and Coolant Temperature Is High. Verify that the problem has been corrected.
2. Check the Cooling System Hose Routing
A. Check the cooling system clamps and hoses to make sure that they 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 3.
Result: The coolant clamps and hoses are not installed properly.
Repair: Repair or replace the damaged cooling system component. Verify that the problem has been corrected. Return
