Antifreeze & Coolant WG12 Concentrate – is a concentrate based on 1.2-ethanediole (mono-ethylene glycol), radiator protection and heat exchanger agent for operation both, summer and winter with permanent frost and rust protection (for all-season use).

Antifreeze & Coolant WG12 Concentrate – has been developed with high quality corrosion additives for motor and cooling system, and meets the current standard in the developement of engine-building.

Antifreeze & Coolant WG12 Concentrate – is free of nitrides, amines, phosphates and silicate.

Wolver Antifreeze WG12 Concentrate is excellently suitable for motors being made of cast iron, aluminium or of a combination of both the metals and at cooling systems being made of aluminium or copper alloyage. 

Wolver Antifreeze WG12 Concentrate is especially recommended for light run motors where a special aluminium protection at higher temperatures is required. 

Recommended working concentration 50 % Wolver Antifreeze WG12 Concentrate and 50% water, radiator protection up to -37 °C can be achieved. Antifreeze protection down to -68 °C is possible with a maximum of 69% Wolver Antifreeze WG12 Concentrate and 31% water. 

Commercial vehicles to 500.000 km (ca. 8.000 hours) 
Passenger cars to 250.000 km (ca. 2.000 hours) 
Stationary engines to 32.000 hours (or 5 years) 

It is recommended, the coolant of radiators, to change all 5 years at the earliest, or if necessary with the achievement of the named stand-times.

Wolver Antifreeze WG12 Concentrate can be mixed with the most of the coolants based on ethylene glycol. 

To achieve an optimal corrosion protection and to avoid sludge formation it is recommended to use pure Wolver AntiFreeze WG12 Concentrate. For the preparation of mixtures softened water should be preferred.
