Troubleshooting Section
Coolant Level
1.
Inspect the coolant level. If necessary, add
coolant.
2.
Check the cooling system for leaks. Repair any
leaks immediately.
Radiator Cap and/or Pressure Relief
Valve
1.
Pressure test the cooling system. Refer to Testing
and Adjusting, “Cooling System” for the correct
procedure.
2.
Check that the seating surfaces of the pressure
relief valve and the radiator cap are clean and
undamaged.
3.
Check operation of the pressure relief valve
and/or the radiator cap. If necessary, clean the
components and/or replace the components.
Coolant Temperature Gauge
Compare the reading for the coolant temperature
from the electronic service tool to the reading for the
coolant temperature from a calibrated test gauge.
Restriction in the Coolant System
1.
Visually inspect the cooling system for collapsed
hoses and/or other restrictions.
2.
Clean the radiator and
fl
ush the radiator. Refer to
Testing and Adjusting, “Cooling System”.
Water Temperature Regulator
Check the water temperature regulator for correct
operation. Refer to Testing and Adjusting, “Cooling
System” for the proper procedure. If necessary,
replace the water temperature regulator. Refer to
Disassembly and Assembly, “Water Temperature
Regulator - Remove and Install” for more information.
Engine Cooling Fan
1.
Make sure that the engine cooling fan is correctly
installed.
2.
Make sure that the engine cooling fan is being
driven correctly by the drive belt. If necessary,
tighten the drive belt or replace the drive belt.
Refer to Disassembly and Assembly, “Alternator
Belt - Remove and Install”.
3.
Check the engine cooling fan for damage. If
necessary, replace the fan. Refer to Disassembly

to Disassembly and Assembly, “Water Pump -
Remove” and Disassembly and Assembly, “Water
Pump - Install”.
Cylinder Head Gasket
Switch off the engine and allow the engine to cool
to below normal working temperature. Remove
the pressure cap for the coolant system. Start the
engine and inspect the coolant for the presence
of bubbles. If bubbles are present in the coolant,
combustion gases may be entering the cooling
system. Check the cylinder head gasket. Refer to the
recommended action for the cylinder head gasket
within Troubleshooting, “Coolant in Engine Oil”.
Check the cylinder head for
fl
atness. Refer to the
recommended action for checking
fl
atness of the
cylinder head within Systems Operations, “Cylinder
Head - Inspect”. Fit the pressure cap if there are no
bubbles in the coolant.
