K2 – Liquid additive to stop leaks 400ml

Liquid sealant to stop leaks for the radiator and other elements of the cooling system.

Fills cracks and remains elastic.
It doesn't clog the system.
Compatible with any type of coolant.
Effectively counteracts corrosion.

Radiator Stop Leak 400ml is a fast-acting, effective and safe liquid sealant for radiators.

Thanks to the unique aluminum microparticles contained in the product, the Stop Leak radiator detects at lightning speed the smallest leak in the radiator and closes it effectively and safely. The preparation does not affect the circulation of antifreeze, so the heat effect of the radiator is not disturbed.

It is safe for all types of radiators. It can be used in combination with all antifreezes.

Application:

Radiator Stop Leak should be shaken well before use.
If the engine is cold and off, open the expansion tank or, if not available, the coolant filler neck.
Caution: a hot radiator should never be opened as this can cause serious burns.
Start the engine and allow it to idle. Wait until the cooler warms up a bit.
Then pour the liquid into the radiator or expansion tank filler hole and then close the radiator or expansion tank.
When this is done, run the engine at 2500-3000 rpm for about 15 minutes so that the sealant is distributed evenly.
If the cooler continues to leak after this, you will likely need to have the radiator completely rebuilt at a service center.
After treatment, Radiator Stop Leak protects the radiator from current leaks and prevents further leaks from forming in the radiator.
