Manufacturer's description
Divinol Radiator Leak Stop (Art-Nr. 61990) is an optimisation product that helps with leaks in the cooling circuit of vehicles. It seals small cracks in the cooling system, such as at seals and hose materials, the cylinder head, the water pump or heat exchangers, and can be used in all vehicles with water-cooled engines. The product combines active ingredients that provide reliable, lasting sealing performance. It does not harden inside the coolant itself, only at points where it comes into contact with ambient air, so it protects against corrosion, remains compatible with normal coolant fluids, and can be flushed out of the cooling system again if needed. To use, shake the can and add the contents to the coolant, for example via the expansion tank, then check the coolant level. With the engine warm and the heater valves open, add the product directly, or let it be drawn in via the expansion tank, then check the coolant level again and drive the vehicle for 10-15 minutes. One 250 ml can is sufficient for approximately 12 litres of coolant.
Applications
- Seals the cooling circuit against small leaks and cracks to prevent coolant loss
- Suitable for all vehicles with water-cooled engines
Performance & benefits
- Reliable, lasting sealing effect from an optimal combination of active ingredients
- Hardens only where it contacts ambient air, not inside the coolant
- Protects against corrosion
- Compatible with standard coolant fluids
- Can be flushed out of the cooling system again
