Effective sealing of small leaks

Bar's Leaks Radiator Stop Leak Powder is specially developed to quickly and efficiently seal small leaks up to 0.9 mm in the cooling system. Whether it's plastic, aluminum, or metal radiators, this product offers a reliable solution for various materials.

Versatile use

This sealant is not only suitable for radiators, but also works effectively on:

• Heater cores
• Water jackets
• Various gaskets, including the head gasket
• Expansion plugs

Easy to use

For optimal results, pour the powder directly into the radiator or through the upper radiator hose. If direct access is not possible, it can also be added to the coolant reservoir. Then run the engine for 15 to 30 minutes or let it idle to circulate the product through the system.

Prevents blockages

Thanks to its special formulation, Bar's Leaks Radiator Stop Leak Powder does not clog the cooling system. The particles are small enough to circulate freely through the system without causing damage, while effectively sealing leaks.

Preventive action

In addition to sealing existing leaks, this product helps prevent future leaks. It continues to circulate in the cooling system, providing long-lasting protection against new leaks.

Recommended dosage

• 4-6 cylinder engines: use 1 bottle of 25 g
• 8 cylinder engines: use 2 bottles of 25 g

For engines with more than 8 cylinders, it is recommended to use 1 bottle of 25 g per 7 liters of coolant.

Cooling system maintenance

For optimal performance, it is important that the cooling system is clean. If the engine is older than 2 years or has driven more than 40,000 kilometers, it is recommended to clean the system with Bar's Flush before using Bar's Leaks Radiator Stop Leak.
