Rislone Radiator Stop Leak
The Rislone Radiator Stop Leak is a professional-grade solution designed to stop minor cooling system leaks and drips caused by normal wear and age. It helps maintain optimal engine temperature and performance while reducing the risk of coolant loss and overheating.
Ideal for automotive, marine, and diesel applications, this product works with all types and colours of antifreeze coolant and can also be used with water, making it a versatile and reliable solution for leak prevention and repair.

Description:
Rislone Radiator Stop Leak is specially formulated to locate and seal minor leaks within the cooling system. It effectively seals leaks in radiators, gaskets, heater cores, and freeze plugs, helping restore system integrity without the need for immediate mechanical repairs.
The formula circulates with the coolant and reacts at leak points to form a durable seal. It is safe for the entire cooling system and does not clog when used as directed, providing both immediate results and ongoing protection.
Specifications:
- Works with all types and colours of antifreeze coolant or water
- Suitable for petrol and diesel engines
- Compatible with radiators, heater cores, gaskets, and freeze plugs
- Non-clogging formula for safe system operation
- Easy pour-and-use application
Key Features:
- Stops and seals minor coolant leaks and drips
- Helps prevent overheating and coolant loss
- Safe for full cooling system components
- No need for draining coolant before application
- Provides continuous protection when left in the system
Applications:
- Automotive cooling systems (cars, vans, trucks)
- Light-duty and heavy-duty diesel engines
- Marine engine cooling systems
- Fleet maintenance and emergency repairs
Usage:
Ensure the engine is completely cool before opening the radiator or coolant reservoir cap.
Opening the cooling system while the engine is hot may cause severe burns.
Shake well before use. Pour Rislone Radiator Stop Leak directly into the radiator. If direct access is not available, add it to the overflow or reservoir tank. Fill the radiator and reservoir to the proper level and reinstall the cap.
Start the engine and allow it to idle or drive for 15 to 30 minutes to circulate the product throughout the cooling system. If the leak continues, a second application may be required or mechanical repair may be necessary. Leave the product in the system for continued protection.
Dosage:
Passenger cars & light trucks – Use one bottle for 6 & 8 cylinder engines, and half bottle for 4 cylinder engines
Heavy-duty equipment – Use one bottle for every 15 liters of coolant capacity
Small systems – Use approximately 20 mL per liter of coolant capacity
Note: Cooling systems that are dirty or partially clogged should be flushed before use. Protect product from freezing.
Using a high-quality radiator stop leak helps reduce coolant loss, prevent overheating, and extend engine life, making it an essential solution for both preventive maintenance and quick repairs.
