Selection Of Coolant: Coolant
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
Relationship between Coolant Concentration and Specific Gravity
CAUTION:
- If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely affected. In addition, 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 a mixture of different brands of anti-freeze.

Example
The safe operating temperature is -15°C (5° F) when the specific gravity is 1.058 at the coolant temperature of 20°C (68°F)
