SERVICE AND MAINTENANCE
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 intercooler coolant may freeze.
• If the intercooler coolant decreases rapidly, go immediately to the nearest Isuzu
Dealer for a check or repair.
• Do not introduce additives to intercooler coolant other than coolant.
CAUTION
• Use only an Isuzu recommended coolant.
• Using any coolant other than that Isuzu recommended could cause damage
to the radiator or intercooler. In particular, use of coolants containing amines,
borate salts, or silicates may result in engine or radiator corrosion, causing
intercooler coolant leaks and other problems.
• Do not use water alone.
