Optima V6-2.7L (2003)
Coolant: Testing and Inspection
SPECIFIC GRAVITY TEST
1. Measure the specific gravity of the coolant with a hydrometer.
2. Measure the coolant temperature, and calculate the concentration from the relation between the specific gravity and temperature, using the
following table for reference.
RELATION BETWEEN COOLANT CONCENTRATION AND SPECIFIC GRAVITY
Example
The safe operating temperature is -15°C (5°F) when the measured specific gravity is 1.058 at coolant temperature of 20°C (68°F).
CAUTION:
^
If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely affected.
^
If the concentration is above 60%, both the anti-freeze and engine cooling properties will decrease, affecting the engine adversely. For these
reasons, be sure to maintain the concentration level within the specified range.
^
Do not use together with another brand.
