6B – 4 ENGINE COOLING
ANTI-FREEZE SOLUTION
Relation between Mixing ratio and Freezing point
Freezing temperature of the engine coolant varies
with the ratio of anti-freeze solution in water.
Proper mixing ratio can be determined by refering
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.
Calculation of mixing ratio
Mixing ratio (%)
=Anti-freeze solution (Lit/qt.)
100
Anti-freeze solution (Lit/qt.) + Water (Lit/qt.)
For example
In case total coolant capacity = 10
It is necessary to mix about 35% anti-freeze
solution at ambient temperature minus 20°C.
Capacity of anti-freeze solution:
35
10 = 3.5 100
Water capacity: 10
– 3.5 = 6.5
Therefore, you prepare the water 6.5 and anti-
freeze solution 3.5
, then mix them to get total
10
coolant.
Mixing ratio
Check the specific gravity of engine coolant in the
cooling system in temperature ranges from 0° C to
50° C using a suction type hydrometer, then
determine the density of the coolant by referring to
the table at below.

ENGINE LUBRICATION 6G – 3
To meet a newly adopted electronically controlled fuel
injection system using engine oil two oil pumps have
been provided to increase circulating oil capacity.
The first oil pump serves mainly to lubricate the engine
parts, while the second mainly serves the fuel injectors
and partially cools the pistons.
The oil cooler is provided on the first oil pump side and
uses engine coolant.
