Product Description
AUTO COOL OPTIMAL (formerly Inugel Optimal)
Antifreeze, radiator coolant, engine coolant
Inugel Optimal is a ready-to-use coolant based on monoethylene glycol. Free from nitrates, amines, phosphates, borates, and silicates. Thanks to a special organic additive technology, engine temperatures are reduced while ensuring optimum performance.
Specifically developed for all-aluminum cooling systems (engine, radiator, etc.).
Does not form a rust-protection film inside the cooling system, resulting in improved heat transfer and significantly better cooling efficiency.
Protects aluminum components against oxidation.
We recommend a complete coolant change when switching to this product. In most cases, approximately 15 liters (3 x 5L) are required.
To fully replace the coolant, the drain at the bottom of the radiator as well as both engine block drains located in the lower area of the block (next to the freeze plugs, on both sides) must be opened.
Only a complete refill with this coolant provides full frost protection and, most importantly, complete corrosion protection.
Not suitable for mixing with other coolants!
Also suitable for modern gasoline and diesel engines.
Freeze protection down to -37 °C.
