Description
Overview:
Silverhook Radiator Stop Leak 325ml is a liquid cooling-system additive for sealing small leaks in water‐cooled petrol and diesel engines. It is formulated with a balanced blend of surfactants, corrosion inhibitors, and sealing agents that circulate with the coolant to locate and close minor weeps in the radiator and associated pipework. Safe for use with rubber hoses, gaskets, and gasket cements, it helps maintain system pressure and reduce coolant loss. Supplied in a durable plastic bottle for easy pouring, it integrates with standard antifreeze without causing sludge or blockages when used as directed. Suitable for cars, vans, light commercial vehicles, plant equipment, and garden machinery with radiators, such as ride‐on mowers and compact generators.
Key Features:
- Quickly seals small leaks in radiators and associated cooling circuits to minimise downtime
- Formulated with surfactants, corrosion inhibitors, and sealants for reliable, long‐lasting performance
- Compatible with antifreeze/coolant for use in mixed or ready‐to‐use coolant systems
- Helps inhibit rust and corrosion to protect radiators, heater cores, and waterways
- Safe for rubber hoses, gaskets, and gasket cements; non‐abrasive and system‐friendly when used correctly
- Suitable for petrol and diesel engines across automotive, plant, and garden machinery applications
- 325ml bottle is easy to pour and simple to apply during routine maintenance or roadside fixes
- Can be used as a preventative measure to reduce the risk of future minor weeps
Typical Applications:
Ideal for sealing pinhole leaks and small weeps in radiators, heater matrices, hose joints, and core plug areas on cars, vans, light commercial vehicles, ride‐on mowers, compact plant, and stationary equipment using water‐cooled engines. Useful for workshop maintenance or emergency top‐ups to stabilise coolant loss until permanent repairs are practical.
