SERVICE AND MAINTENANCE
- 5–10 -
CAUTION
Replace the engine coolant
periodically.
If the engine coolant is not replaced
periodically, rust is generated due to
degradation of the engine coolant,
which may cause a failure such as
water leakage or clogging of the
radiator or heater core.
NOTE
Engine coolant is fluid which is made
by mixing coolant and water (distilled
water or deionized water) at an
appropriate concentration.
Preparing engine coolant
To prevent the engine damage due to
freezing of the engine coolant and to
protect the cooling system from corrosion,
mix the Isuzu recommended coolant and
water (distilled water or deionized water)
to be at 50% concentration.
For other than Isuzu genuine coolant
(Arteco/BASF/Total, etc.), it is
recommended to use directly "50/50 Pre-
diluted" product which is already diluted
to 50% concentration.
Refer to "RECOMMENDED FLUIDS,
LUBRICANTS AND DIESEL FUELS" in
this section for Isuzu recommended
coolant.
CAUTION
• Isuzu does not guarantee the use of
the engine or vehicle at the outside
temperature of -30°C (-22°F) or
below.
• However, if the engine or vehicle is
used at the outside temperature of
-30°C (-22°F) or below, the coolant
concentration of 55% is
recommended.
