Nural- 70 Auto Coolant Circuit (8 Liter Can)

Nural- 70 Auto Refrigerant Circuit (8 Liter Can).
- 8 litre can.
- Protects against oxidation and corrosion, preventing the formation of lime scale and lubricating the water pump. Repairs internal leaks (towards the combustion chamber or to the oil through the cylinder or sleeve, cylinder head gasket, etc.) and external leaks (through the radiator, heater, block, cylinder head, hoses, etc.).
- With the engine stopped, add Pattex Nural 70 through the radiator cap, or if there is none, through the expansion tank, allowing all the solid granules to fall out. If the granules are too hard, you can soften them by adding a little water and grinding them. Run the engine until it warms up (minimum time: 30 minutes) and allow the product to circulate through the entire circuit, radiator, block and heating, opening the latter for a few minutes.
- It is recommended to clean the circuit beforehand 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 pipes larger than 0.5 mm in pitch.
- Pattex Nural 70 is not suitable for repairing leaks larger than 0.8mm in pitch. For any special use, please consult Henkel beforehand.
