Nural 70 Auto

Cooling circuit treatment
Radiator covers that prevent water leakage and engine overheating. Does not obstruct.

▪ Protects against oxidation and corrosion by preventing limescale build-up and lubricating the water pump. Repair internal (combustion chamber, jacket, breech gasket, porosity in block or breech, etc.) and external (through radiator, heating, block, breech, hoses, buffers, etc.).

▪ Lay Pattex Nural 70, through the radiator cap, and if not, through the expansion tank, dropping all solid particles. If the particles are too hard they can be softened by adding a little water and grinding them
▪ Start the engine until it is warm (minimum time: 30 minutes) to allow circulation of the product through the circuit, radiator, block and heating, opening the latter for a few minutes
