Coolant: Testing and Inspection

Inspection

Relationship Of Coolant Concentration And Freezing Temperature

The concentration and safe operating temperature of the coolant is shown in the diagram. Measuring the temperature and specific gravity of the coolant
will provide this information.

^

If the coolant temperature is 25°C (77°F) and its specific gravity is 1.054, the concentration is 45% (point A), the safe operating temperature is -14
°C (7°F)
 (point B), and the freezing temperature is -20°C (-4°F) (point C).

Procedure To Adjust The Concentration Of The Coolant

To adjust the concentration of the coolant according to temperature, find the proper fluid concentration in the above diagram and replace the necessary
amount of coolant with an undiluted solution of genuine coolant (concentration 50%).

The amount of coolant that should be replaced can be determined using the diagram.

^

Assume that the coolant concentration must be increased from 25% to 40%. Find point A, where the 25% line of coolant concentration intersects
with the 40% curve of the necessary coolant concentration, and read the scale on the vertical axis of the graph at height A. The quantity of coolant
to be drained is 2.1 liters (2.2 US qt, 1.8 Imp qt). Drain 2.1 liters (2.2 US qt, 1.8 Imp qt) of coolant from the cooling system and add 2.1 liters
(2.2 US qt, 1.8 Imp qt)
 of the undiluted solution of coolant.

If a coolant concentration of 50% is needed, drain all the coolant and refill with the undiluted solution only.
