COOLANT M3.1 on an ethylene glycol basis offers outstanding protection against freezing, corrosion, limescale and overheating in state-of-the-art engines, especially highly stressed aluminium engines. The inhibitors used effectively prevent corrosion and deposits in the key components of the cooling system, such as cooling channels in the cylinder head and engine block, cooler, water pump and heat exchanger.
Field of application
COOLANT M3.1 Concentrate is recommended by notable vehicle manufacturers. Thanks to its optimum inhibitor technology, the coolant offers reliable protection for the entire cooler system.
