DRIVANO CoolBlue A11

All-season amine and phosphate-free mono-ethylene glycol based coolant with frost and rust protection for Mercedes, BMW, Opel, Saab and General Motors engines. This product is formulated based on a proven inhibitor development by combining silicates with the organic additive technology OAT as an extended life coolant. The quality of an antifreeze is no longer just determined by the antifreeze effect (which automatically exists in an ethylene-glycol based product), but by the rust protection. That is why automakers subject antifreeze to lengthy corrosion and cavitation tests. It protects the cooling system from rust, frost, and in summer, from overheating.
