Coolant MOTUL AUTO COOL OPTIMAL ULTRA 1L

MOTUL AUTO COOL OPTIMAL ULTRA is a long-life concentrated coolant that must be mixed with demineralised water; based on monoethylene glycol, with organic acid inhibitors (OAT), designated as ‘Organic Tech’. Particularly recommended for any cooling system: passenger cars, heavy vehicles, construction and agricultural vehicles, gardening, boats, stationary engines, etc.

Excellent protection of cooling systems against freezing and metal parts against corrosion. OAT coolant technology provides excellent heat exchange and therefore improves engine cooling efficiency. This organic technology provides anti-corrosive properties that remain effective at high temperatures. Reduced consumption of corrosion inhibitors allows for extended change intervals. Protection of water pumps, prevents cavitation. Compatible with gaskets, hoses, pipes and plastic components.

Do not use the product undiluted.

Mix with demineralised/distilled water, according to the required frost protection. 

To maintain anti-corrosion properties, do not dilute below 33%. Water for dilution: If possible, use demineralised/distilled water: Maximum hardness of 35°F and maximum chloride and sulphate content of 500 ppm.

Drainage intervals: Consult the manufacturer's recommendation.

Warning: only check or drain the coolant when the engine is cold. Do not mix with non-organic products (IAT). This product must not be used to protect drinking water systems against freezing. Dangerous. Follow the recommendations for use and handling.
