Radiator Leak Stop (13 oz)

DVX Radiator Leak Stop is a sealing treatment developed to help stop small leaks in automotive cooling and heating systems. It helps seal cracks and small openings that may cause coolant loss while supporting reliable operation of the cooling system.

The formula is suitable for cooling radiators regardless of their construction material and can be used in both engine cooling radiators and interior heating systems. It works with both water and antifreeze-based coolants and is designed to help protect the system against corrosion.

In addition to sealing small leaks, the formula helps prevent clogging in radiator waterways and temperature sensors, lubricates the water pump seal, and supports coolant electrolysis control.

Applications

Suitable for:

• Engine cooling radiators
• Vehicle interior heating radiators
• Water- and antifreeze-based cooling systems
• Cooling systems with small cracks, holes, or leaks causing coolant loss
• Cooling systems requiring additional corrosion protection

How to Use

1. Shake the container thoroughly before use.
2. Do not open the radiator cap while the radiator or cooling system is very hot.
3. For vehicles with a cooling system capacity of 2 to 18 liters, use 1 container (300 ml).
4. For vehicles with a cooling system capacity greater than 18 liters, use 2 to 3 containers.
5. Add the required amount of product to the cooling system.
6. Turn on the vehicle's heater.
7. Run the engine for approximately 10 minutes to allow the product to circulate throughout the cooling system.
