Nural- 70 Auto Refrigerant Circuit (8-liter can).
- 8-liter can.
- Protects from oxidation and corrosion, preventing the formation of lime scale and lubricating the water pump. Repairs internal leaks (to the explosion chamber or to the oil through the cylinder or liner, head gasket, etc.) and external leaks (through the radiator, heater, block, cylinder head, hoses, etc.).
- Add Pattex Nural 70, with the engine stopped, through the radiator cap, and if not, through the expansion tank, making all the solid granules fall. If the granulate is too hard, it can be softened by adding a little water and crushing it. Run the engine until it warms up (minimum time: 30 minutes) and allow the product to circulate through the entire circuit, radiator, block and heater, opening the latter for a few minutes.
- It is recommended to previously clean the circuit with Pattex Nural 1 and renew the coolant before adding a dose of Pattex Nural 70. The product should not be removed after use. Use Pattex Nural 70 in circuits with conduits greater than 0.5mm pitch.
- Pattex Nural 70 is not suitable for repairing leaks greater than 0.8mm pitch. For any special use, consult Henkel in advance.
