AUTO COOL OPTIMAL

MOTUL AUTO COOL OPTIMAL -37°C is a ready-to-use coolant,

ULTRA

Concentrated coolant

Anti-corrosion and anti-freeze

Technology based on organic acids OAT

Without nitrites, amines, phosphates, borates, silicates

USE

MOTUL INUGEL OPTIMAL ULTRA is a concentrated coolant liquid, based on monoethylene glycol, with

organic type additives (OAT – Organic Acid Technology), to be diluted with water, preferably

demineralized.

Particularly recommended for the cooling circuits of: motor vehicles, heavy vehicles, moving vehicles

land, agricultural, gardening, boats, stationary engines, etc.

PERFORMANCE

MANUFACTURER'S STANDARDS AND APPROVALS: refer to the attached table.

The product is made bitter in order to avoid ingestion. In fact, coolants are harmful in spite of

may have a sweetish taste.

Excellent protection of cooling circuits against freezing and against metal corrosion. There

technology based on organic acids OAT promotes heat exchange allowing effective cooling of the

engine and raising the boiling point.

Organic technology retains its anti-corrosion properties over time and at high temperatures.

The limited consumption of corrosion inhibitors allows longer drain intervals. Prevents the

cavitation phenomenon ensuring a longer life of the water pump.

Compatible with gaskets, plastic parts and sleeves.

RECOMMENDATIONS

Do not use the pure product, dilute in demineralised water with a variable percentage according to the

protection sought, see table. To maintain the minimum anti-corrosion properties, dilute the product at least to

33%.

Dilution water: use demineralised water where possible. Maximum hardness 35°Fr and maximum content of

chlorates and sulphates of 500ppm.

Drain intervals: in accordance with the manufacturers' recommendations.

Warning, check or replace coolant with cold engine.

Do not mix with non-organic products.

Do not use the product for frost protection of potable water supply systems.

Dangerous. Respect the recommendations regarding the use and handling of the product.

PROPERTY'

Does not contain Nitrites, Amines, Phosphates, Borates and Silicates.
