INSPECTION AND MAINTENANCE
Inspecting the Coolant
Inspect the radiator and radiator hose for a crack, damage and water leakage. Also,
check whether water leakage stains have been left on the ground surface where the
machine is set. When a crack, damage or water leakage is found, contact an Isuzu
Distributor.
CAUTION
Running the engine without fixing the water leakage could result in an engine
seizure.

Replacing the Coolant
Clean the coolant passages using a cleaning agent. Also, clean the radiator, radiator
cap, and intercooler.
It is recommended to use the Isuzu genuine radiator cleaner for cleaning of coolant
passages.

ADVICE
After the coolant is discharged, do not start the engine when there is no water
in the radiator. This could cause the engine to seize up.
Hand tighten the drain cock of the radiator. Tightening with pliers or some
other tool could damage it.
Disposal and treatment of the discharged coolant must be conducted in
accordance with the specified procedure.
