RAVENOL OTC Org. Techn. Coolant HOT CLIMATE -15°C is a ready-to-use, prediluted with water, eco-friendly 1.2- Ethanediol (monoethylene glycol) based silicate, borate, nitrite and phosphate-free coolant for cooling circuits in combustion engines which provides maintenance-free corrosion and frost protection. This product is formulated based on a proven inhibitor development 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.

RAVENOL OTC Org. Techn. Coolant HOT CLIMATE -15°C protects the cooling system from rust, frost, and in summer, from overheating.

Application Note

RAVENOL OTC Org. Techn. Coolant HOT CLIMATE -15°C is a prediluted coolant with frost and rust protection for year-round use in automotive engines.

Even in summer coolant must contain enough antifreeze to ensure good corrosion and overheating protection.

Instructions: Add RAVENOL OTC Org. Techn. Coolant HOT CLIMATE -15°C to radiator to fill line.
