INSPECTION AND MAINTENANCE
Coolant
The coolant is a type of fluid which is made by mixing tap water and the long-life
coolant "BESCO LLC SUPER TYPE E or BESCO LLC SUPER TYPE AS" with an
appropriate ratio. It has the function of cooling off the heat generated by the engine.
Periodic Inspection and Maintenance
List → Refer to Page 5-36
WARNING
Inspection, adding or replacement of the coolant should be performed when
the engine has cooled down sufficiently.
Do not loosen or remove the cap of the radiator or reserve tank when the
temperature of coolant is still high. Hot vapor or boiling water may burst out
and cause a burn. Cover the cap with a cloth, etc. and remove it gradually
when the engine has cooled down sufficiently and the temperature of the
coolant has dropped.

ADVICE
Replace the coolant periodically.
When the coolant is not replaced periodically, rust may be generated due to
degradation of the coolant, which may cause a water leakage or clogging of
the radiator or heater core.

Handling the Long-life Coolant
To prevent the engine damage due to freezing of the coolant and to protect the
cooling system from corrosion, mix the Isuzu specified long-life coolant (LLC) and tap
water with an appropriate ratio.
