Nitrite free / Amine free / Phosphate free / Borate free / Silicate free
Application:
- MOTUL AUTO COOL OPTIMAL -37°C is a ready to use long life cooling liquid, based on monoethyleneglycol, using an Organic Acid Technology (OAT) additivation named Organic Tech.
- Strongly recommended for all cooling systems: passenger cars, heavy duty, construction and agriculture vehicles, gardening, ships, stationary engines etc
Key Benefits:
- Contains a bitterness agent to prevent from drinking: coolants and antifreezes have a sweet taste but are harmful.
- Optimal protection of cooling systems against freezing and metallic parts against corrosion. OAT coolant technology provides an excellent thermal exchange and therefore improves engine cooling efficiency and prevents from boiling.
- This organic technology provides anti-corrosion properties that remain at high temperature and aging.
- Low corrosion inhibitors consumption allows extended drain intervals.
- Water pump protection, avoids cavitation.
- Seals, hoses, pipes and plastic parts friendly.
Recommendations:
- Ready to use, do not add any water.
- Drain intervals: Refer to the manufacturers' recommendation.
- Do not mix with non-organic products.
- This product should not be used to protect drinking water systems against freezing.
- Attention, control or drain the coolant only when the engine is cold.
- Dangerous. Respect the use and handling recommendations.
