Trooper S 4WD V6-35L (2002) Maintenance: Coolant Specifications
Coolant: Description and Operation
Anti Freeze Solution
Relation between the mixing ratio and freezing temperature of the Engine Coolant varies with the ratio of anti-freeze solution in water. Proper mixing
ratio can be determined by referring to the chart. Supplemental inhibitors or additives claiming to increase cooling capability that have not been
specifically approved by Isuzu are not recommended for addition to the cooling system.

Calculating mixing ratio
Notice: Antifreeze solution + Water = Total cooling system capacity.
Mixing Ratio
Check the specific gravity of engine coolant in the cooling system temperature ranges from O°C to 50°C using a suction type hydrometer, then
determine the density of the engine coolant by referring to the table.
Notice:
1. Even in the areas where the atmospheric temperature is higher than 0°C, be sure not to use antifreeze solution at a mixing ratio lower than 20% so
that the inside of the engine may not be corroded.
