## Long description

K2 Radiator Stop Leak T233 is a 250 ml sealant formulated to stop minor leaks and seepage in automotive cooling systems. Designed for temporary repair, it is suitable for use in radiators, heater cores and various cooling circuit joints where small leaks or weeping occur. The product mixes with common engine coolants and works to reduce coolant loss and lower the risk of overheating until a permanent repair can be performed.
Advantages
The sealant restores system integrity by sealing hairline cracks and small joint leaks without dismantling the cooling system. It is compatible with most conventional and long-life antifreeze formulations and does not require special tools or procedures for application. Because it is supplied in a compact 250 ml container, the product is convenient to store in a vehicle for emergency use and provides a fast, temporary mitigation of coolant loss and temperature rise.

How to use
Ensure the engine is cool before opening the cooling system. Shake the bottle well and add the recommended amount of sealant directly into the radiator or expansion tank according to the vehicle manufacturer’s coolant level. Start the engine and allow it to reach normal operating temperature so the sealant can circulate and act on leak sites. Monitor coolant level and temperature after application and recheck for leaks. This product provides a temporary repair and should be followed by professional inspection and permanent repair as soon as practical.
Usage recommendations
Use only for small leaks and seepage; do not use as a substitute for full mechanical repair. Avoid application to cooling systems with major damage or large holes. Store in a cool, dry place away from direct sunlight and keep out of reach of children. Follow vehicle manufacturer guidelines for coolant type and quantity when adding the sealant.
