temperature of 20°C (68°F).
Caution
1. If the concentration of the coolant is below
affected. In addition, if the concentration is above
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain the
concentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.
