Coolant antifreeze 50% -37º 5L Motul Cool Optimal Yellow

Coolant antifreeze liquid 50% -37º 5L Motul Cool Optimal Yellow

Motul Auto Cool Optimal Yellow -37 °C is a long-life coolant, ready to use, based on monoethylene glycol, using an organic acid technology (OAT) additive called Organic Tech.

Performance:

• Contains a bittering agent to prevent ingestion: coolants and antifreezes have a sweet taste but are harmful.
• Optimal protection of cooling systems against freezing and of metal parts against corrosion.
• OAT coolant technology provides excellent heat exchange and therefore improves engine cooling.
• Efficiency and prevents boiling.
• This organic technology provides anticorrosive properties that are maintained at high temperatures and with aging.
• The low consumption of corrosion inhibitors allows for extended drain intervals. Protection of water pumps, prevents
• cavitation.
• Compatible with seals, hoses, pipes, and plastic parts.

Recommendations:

• Ready to use, do not add water.
• Drain intervals: consult the manufacturer's recommendations.
• Do not mix with non-organic products.
• This product should not be used to protect drinking water systems against freezing.
• Attention, check or drain the coolant only when the engine is cold.
• Dangerous. Follow the usage and handling recommendations.
