## Long description

IWH K-Seal Universal Radiator Leak Repair 236 ml Cooling System Sealer is a reliable cooling system sealer formulated to permanently stop coolant leaks in vehicle engines. Supplied in a convenient 236 ml bottle, this radiator leak repair sealant is engineered for fast and straightforward application, effectively sealing cracks and leaks in radiators, cylinder heads, and gaskets without clogging the cooling passages.
Advantages
The primary advantage of this cooling system sealer is its ability to provide a permanent repair for multiple components within the cooling circuit, including the radiator and cylinder head, saving time and costly repair bills. Its advanced formulation ensures that it targets the source of the leak quickly without interfering with normal coolant flow or blocking the system, making it a dependable choice for both preventive maintenance and unexpected roadside repairs.
Suitable for
Permanent repair of radiator leaks in cars and other vehicles
Fixing coolant leaks in cylinder heads and gaskets
Emergency roadside repairs when coolant is dropping
Routine vehicle cooling system maintenance
When it may not be suitable
This product may not be suitable for large-scale structural damages, severe mechanical failures, or massive ruptures where coolant escapes too rapidly for the sealant to activate. It is also not intended for systems heavily contaminated with rust or scale that require a complete mechanical overhaul rather than chemical sealing.
Key specifications
Volume: 236 ml
Type: Universal radiator leak repair and cooling system sealer
Application: Suitable for radiators, cylinder heads, and gaskets
Form: Liquid sealant
How to use
Ensure the engine is cool before starting the procedure. Shake the bottle well to mix the contents thoroughly. Remove the radiator cap or coolant expansion tank cap, and pour the contents directly into the cooling system. Top up with coolant or water if necessary, replace the cap securely, and start the engine, allowing it to idle or driving the vehicle for a short period to circulate the product throughout the cooling circuit.
What to consider before purchase
Verify that the cooling system capacity aligns with the 236 ml volume of the bottle
Check that the issue is a minor leak rather than a major mechanical component failure
Ensure the cooling system is reasonably clean and free from heavy blockages
Usage recommendations: For optimal results, follow vehicle manufacturer instructions regarding coolant levels and ensure the engine operates at normal working temperature after application to activate the sealing process effectively.
