Specific Gravity Test

1. Measure the specific gravity of the coolant with a suitable hydrometer.
2. Measure the coolant temperature, and calculate the concentration from the relation between the specific gravity and temperature. Use the following table for reference.






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, adversely affecting the engine.
- For these reasons, be sure to maintain the concentration level within he specified range.
- Do not mix brands of coolant.

RECOMMENDED COOLANT
Ethylene Glycol Base For Aluminum
Mixture ratio of anti-freeze in coolant
Except tropical areas, 50%
Tropical areas, 40%
