## Long description

Technicoll T230 Stop Leak is a powdered radiator sealant supplied in an 18.5 g dose for rapid, temporary repair of coolant system leaks. The powder is formulated to mix with engine coolant and form sealing compounds that close small cracks, pinholes and minor gasket leaks in radiators, hoses and cooling circuit connections. It is intended as an emergency or interim solution to restore system tightness and reduce coolant loss until permanent workshop repair can be performed.
Advantages
This powdered sealant dissolves in coolant and is easy to apply without disassembling the cooling system. It provides a fast response to small leaks and helps prevent rapid coolant loss that could lead to engine overheating. The compact 18.5 g dose is convenient to store in a vehicle emergency kit and is compatible with common coolant types used in automotive cooling circuits.
Suitable for
Sealing small cracks and pinholes in radiators and heater cores
Stopping minor leaks at hose joints and clamps
Temporary repair of minor gasket leaks in cooling systems
Emergency roadside fixes and short-term use before workshop repair
Key specifications
Form: powdered sealant in a single 18.5 g dose
Application area: engine cooling circuits, radiators, hoses, heater cores
Compatibility: designed to mix with conventional automotive coolant
Intended use: temporary/emergency sealing of small leaks and pinholes
How to use
Ensure the engine is cool before opening the cooling system. Add the entire 18.5 g dose of the powder to the coolant reservoir or expansion tank according to the vehicle manufacturer’s instructions. Start the engine and allow it to reach normal operating temperature so the powder can circulate and react with the coolant at the leak site. Monitor coolant level and temperature; if leaks persist or the engine overheats, stop driving and seek professional repair.
Usage recommendations
Use Technicoll T230 Stop Leak only as a temporary measure. Do not use it as a substitute for proper repair of structurally damaged radiators or major gasket failures. Store the product in a dry place and follow vehicle manufacturer guidelines for coolant type and maintenance. If multiple applications are required or if the leak is large, consult a workshop for a permanent repair.
