Customer Questions & Answers

  • Question: What is K-Seal ST5501 and how does it work?

    Answer: K-Seal ST5501 is a multi-purpose, one-step permanent coolant leak repair solution designed to seal leaks in your vehicle’s cooling system. It works by utilizing a unique blend of ceramic and metallic compounds that flow to the leak and bond with the existing materials. This creates a permanent seal without the need for complicated procedures, making it ideal for quick repairs. For instance, if you notice coolant dripping under your car, simply pour K-Seal into the radiator, and it will mix with the existing antifreeze, sealing the leak effectively.
  • Question: Can I use K-Seal ST5501 with all types of antifreeze?

    Answer: Yes, K-Seal ST5501 is compatible with all types of antifreeze, making it versatile for various vehicles. It mixes seamlessly with both conventional and organic acid technology-based coolants, ensuring that it won’t cause any chemical reactions. By using K-Seal, you can fix leaks in different vehicles without worrying about the coolant type. This is especially useful for multi-vehicle households or workshops that service diverse engine types.
  • Question: How do I apply K-Seal ST5501?

    Answer: Applying K-Seal ST5501 is simple and straightforward. Just shake the bottle well, then pour the entire 8-ounce content directly into the radiator or overflow tank. There's no need for flushing or draining your system beforehand. Once added, the product immediately begins to work to seal leaks, making it a hassle-free solution for sudden coolant loss. This method is perfect for those who want to avoid complex repair processes and save time.
  • Question: Is K-Seal ST5501 permanent?

    Answer: Yes, K-Seal ST5501 is designed to provide a permanent solution to coolant leaks. Unlike temporary fixes like sealing tapes or stop-leak products that may wash out, K-Seal forms a strong bond within the leaking areas of your cooling system. Once applied, it remains effective and durable, even under high pressure and temperature conditions. It’s an excellent choice for anyone looking for a long-term fix to their vehicle’s coolant leak issues.
  • Question: What types of leaks can K-Seal ST5501 repair?

    Answer: K-Seal ST5501 can repair various leaks in the cooling system, including those found in radiators, water pumps, head gaskets, and heater cores. Its specialized formula allows it to seal cracks and holes effectively, preventing coolant loss. For example, if you notice your vehicle overheating due to a small leak, using K-Seal can swiftly address the issue without the need for extensive repairs, making it a reliable emergency solution.
  • Question: Can K-Seal ST5501 be used in both cars and trucks?

    Answer: Absolutely! K-Seal ST5501 is suitable for use in both cars and trucks, regardless of size or engine type. Its formulation is designed to handle the different pressures and requirements of various cooling systems, making it a universal choice for all vehicles. If you own multiple types of vehicles, K-Seal can serve as a valuable addition to your tool kit for quick and efficient coolant leak repairs.
  • Question: How long does it take for K-Seal ST5501 to work after application?

    Answer: K-Seal ST5501 starts working immediately after application. Once you pour it into the cooling system, the compounds will begin to flow and bond to the leak sites almost instantly. However, it is recommended to run the engine for at least 15-30 minutes to allow the product to circulate and fully seal the leaks. This quick activation makes it ideal during emergencies when immediate action is needed.
  • Question: Is K-Seal ST5501 safe for my vehicle’s cooling system?

    Answer: Yes, K-Seal ST5501 is safe for all vehicle cooling systems. It is non-toxic and will not harm engine components. The formulation is specifically designed to be effective without causing damage to rubber, metal, or plastic parts commonly found in cooling systems. This makes it a reliable option for those concerned about long-term effects on their vehicles after applying a leak sealant.
  • Question: What should I do if K-Seal ST5501 doesn’t stop the leak?

    Answer: In cases where K-Seal ST5501 does not stop the leak, it is advisable to consult a professional mechanic for further inspection. While K-Seal is highly effective, some severe leaks may require more extensive repairs. However, if you follow the application instructions carefully and still have issues, there may be underlying problems within the cooling system that need professional assessment. Always check for signs of other issues such as overheating or persistent coolant loss.
