Engine Coolant
2. RELATIONSHIP OF SUBARU COOLANT
CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of the SUBARU Genuine Coolant is shown in the
diagram. Measuring the temperature and specific
gravity of the coolant will provide this information.
[Example]
If the coolant temperature is 25°C (77°F) and its
specific gravity is 1.054, the concentration is 35%
(point A), the safe operating temperature is −14°C
(7°F) (point B), and the freezing temperature is −
20°C (−4°F) (point C).
3. PROCEDURE TO ADJUST THE CONC
ENTRATION OF THE COOLANT
To adjust the concentration of the engine coolant
according to temperature, find the proper fluid con-
centration in the above diagram and replace the
necessary amount of coolant with an undiluted so-
lution of SUBARU Genuine Coolant (concentration
50%).
The amount of coolant that should be replaced can
be determined using the diagram.
[Example]
Assume that the engine coolant concentration must
be increased from 25% to 40%. Find point A, where
the 25% line of the engine coolant concentration in-
tersects with the 40% curve of the necessary the
engine coolant concentration, and read the scale
on the vertical axis of the graph at height A. The
quantity of the engine coolant to be drained is 2.12
(2.2 US qt, 1.8 Imp qt). Drain 2.12 (2.2 US qt, 1.8
Imp qt) of coolant from the cooling system and add
2.12 (2.2 US qt, 1.8 Imp qt) of the undiluted solu-
tion of SUBARU Genuine Coolant.
If the engine coolant concentration of 50% is need-
ed, drain all the coolant and refill with the undiluted
solution only.
