Thermostat
The thermostat is a bypass type and is a wax pellet type
with a air hole (1).
Radiator
The radiator is a flow type with corrugated fins.
Antifreeze Solution
f 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 that have not been specifically approved by
Isuzu are not recommended for addition to the cooling
system.

f 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.
