3. Cylinder Head
A. Check for cracks in the cylinder head. Perform a leak test on
the cylinder head. Refer to System Operation, Testing and Ad-
justing, "Cylinder Head - Inspect" for the correct procedure.
4. Cylinder Block
A. Inspect the top face of the cylinder block for faults and signs
of leakage.
Refer to Systems Operation, Testing, and Adjusting, "Cylinder
Block - Inspect" for the correct procedure.

Coolant Level Is Low

Note: On engines equipped with a Diesel Exhaust
Fluid (DEF) system, the DEF tank requires coolant
flow around the tank. The coolant diverter valve will
turn the flow to the DEF tank on or off. If the coolant
system is filled when the coolant diverter valve is
CLOSED , the coolant level will drop when the
coolant diverter valve is opened. This situation does
not necessarily indicate a fault.
Inspect the cooling system for leaks. Refer to
Systems Operation, Testing and Adjusting, "Cooling
System - Test" for the correct procedure.
