Ravenol ETC Concentrate Protect C12evo coolant concentrate

Ravenol ETC Concentrate Protect C12evo is a coolant concentrate for engine cooling systems, class C12evo and G12evo. It is based on 1,2-ethanediol (monoethylene glycol) and uses Si-OAT technology, in which organic acids work together with mineral silicates. It contains no borates, nitrites, phosphates, amines or 2-ethylhexanoic acid (2-EHA).

Its long-term corrosion protection lasts up to 5 years and covers all metals and alloys used in cooling systems, aluminium included. It is compatible with the elastomers used in car radiators and can be mixed with all other types of antifreeze.

Never use the concentrate undiluted: mix it with demineralised or distilled water. The maker recommends a 50:50 mix by volume, and the concentrate share should be between 35% and 60%.

Ravenol is a German lubricant maker from Ravensberg whose range includes gearbox oils and special fluids.
