SERVICE AND MAINTENANCE
WARNING
• Coolant is toxic and must not be ingested. If the coolant is mistakenly ingested,
immediately vomit it and seek prompt medical attention.
• If the coolant gets in your eyes, rinse it off immediately with a large amount of
water for 15 minutes or longer. Also, if still abnormality such as irritation is felt,
seek medical attention.
• If the coolant gets on your skin, rinse it off using a soap with a large amount of
water. Also, if abnormality is seen, seek medical attention.
• For storage, close the cap securely and keep it in a place inaccessible to
children.
• Coolant is flammable, and therefore, it must be kept away from flames and other
heat sources. Coolant also could ignite if it comes in contact with a hot surface,
such as the exhaust manifold. Exercise caution to prevent this from happening.
CAUTION
• Use only an Isuzu recommended coolant.
• Using any coolant other than that Isuzu recommended could cause damage
to the engine, radiator, or heater core. In particular, use of coolants containing
amines, borate salts, or silicates may result in engine or radiator corrosion,
causing engine coolant leaks and other problems.
• Do not use water alone.
ADVICE
• To dilute the coolant, use distilled water or deionized water.
• Do not use the coolant at any coolant concentration other than that specified. If
the coolant concentration is 60% or higher, overheating is likely to occur, while if
it is 30% or lower, anti-corrosion function is not provided sufficiently.
• Using coolant at any coolant concentration other than that specified may reduce
anti-freezing performance, and engine coolant may freeze.
• If the engine coolant decreases rapidly, go immediately to the nearest Isuzu
Dealer for a check or repair.
• Do not introduce additives to engine coolant other than coolant.
