The Motul Auto Cool Expert Concentrated Ultra Coolant / Anti Freeze is designed for vehicle owners seeking robust engine protection in extreme temperatures. Its key benefit is providing exceptional freeze and overheat protection down to -37° C, suitable for a wide range of vehicles. A primary consideration is that this product is a concentrate and requires careful mixing with soft water before use, meaning it's not a ready-to-use solution.

Concentrated coolant, like Motul Auto Cool Expert, must be mixed with water (typically 50/50) to achieve its full protective properties. Ready-to-use coolant is already pre-mixed with water and can be added directly to the system.
No, it is essential to use soft water, such as demineralized or distilled water. Tap water contains minerals that can cause scale buildup, reduce cooling efficiency, and lead to corrosion.
OAT stands for Organic Acid Technology, and IAT stands for Inorganic Additive Technology. Motul Auto Cool Expert uses a hybrid formulation combining both for enhanced protection and longevity.
The replacement interval depends on the vehicle manufacturer's recommendations and the coolant's formulation. For Motul Auto Cool Expert, it typically provides protection for 2-4 years or a specified mileage, but always refer to your vehicle's service manual.
Yes, coolant plays a vital role in both preventing freezing in cold weather and maintaining optimal operating temperatures to prevent overheating in warm weather.
It is a universal coolant suitable for all types of cooling systems in cars, trucks, and heavy-duty equipment that use mono-ethylene glycol-based coolants, provided it is mixed correctly.
Ensure accurate measurement of coolant and soft water during mixing. Use a hydrometer or refractometer to verify the mixture's freeze protection level.
Check coolant level, ensure the mixture is correct, and verify the radiator, thermostat, and water pump are functioning properly. Look for any blockages in the cooling system.
Use only soft (demineralized or distilled) water for mixing. Flush the system thoroughly if it contains contaminants from previous use.
While designed for broad compatibility, it's best to flush the system completely before adding Motul Auto Cool Expert if unsure about the previous coolant type.
Setup: This product is a concentrate and must be mixed with soft water before use. The recommended mixing ratio depends on the desired level of freeze protection:
Always use demineralized or distilled water for mixing to avoid mineral deposits that can impair cooling efficiency and cause corrosion.
Compatibility: Motul Auto Cool Expert is designed to be mixed with all mono-ethylene glycol-based coolants. It meets numerous OEM specifications, including VAG TL-774 C (G11), BMW GS 9400, Mercedes Benz MB 326.0 / MB 326.2, and Ford ESD-M97B49-A. Always consult your vehicle's owner's manual to confirm coolant type requirements.
Care: Ensure the cooling system is clean before filling. Flush the system with water if switching from a different type of coolant. Periodically check the coolant level in the expansion tank when the engine is cold. Inspect coolant for signs of contamination (e.g., rust, oil, or sludge) and replace if necessary, typically every 2-4 years or as recommended by the vehicle manufacturer.
