Coolant: Description and Operation

ANTIFREEZE SOLUTION
- Relation between mixing ratio and Freezing temperature of the engine coolant varies with the ratio of antifreeze solution in water. Proper mixing ratio can be determined by referring to the chart. Supplemental inhibitors or additives claiming to increase cooling capability/hat have not been specifically approved by Isuzu are not recommended for addition to the cooling system.





- Calculating mixing ratio

NOTE: Antifreeze solution + Water = Total cooling system capacity.

- Total Cooling System Capacity 5.7 Lit (1.50 U.S. Gal)





- Mixing ratio
Check the specific gravity of engine coolant in the cooling system temperature ranges from 0°C to 50°C using a suction type hydrometer, then determine the density of the engine coolant by referring to the table.
