One product that has stood out to me is the K Seal Heavy Duty Permanent Coolant Leak Sealer ST5516. In this buying guide, I will share my first-hand experience and provide all the necessary information to help you make an informed decision when purchasing this product.
What is K Seal Heavy Duty Permanent Coolant Leak Sealer ST5516?
K Seal Heavy Duty Permanent Coolant Leak Sealer ST5516 is a unique formula designed to permanently repair leaks in the cooling system of heavy-duty vehicles such as trucks, buses, tractors, and other industrial machinery. It is compatible with all types of antifreeze and can seal leaks in radiators, heater cores, freeze plugs, water pumps, and head gaskets.
Why choose K Seal over other coolant leak sealers?
Having tried various coolant leak sealers in the past, I can confidently say that K Seal stands out for several reasons:
- Easy to use: Unlike other sealers that require draining the coolant system or removing components for application, K Seal can be poured directly into the radiator or expansion tank.
- Permanent fix: K Seal uses a unique ceramic microfiber technology that forms a strong bond with metal surfaces to create a permanent seal. This means you won’t have to worry about reapplying the sealer every few months.
- No clogging: The fine particles in K Seal are small enough not to clog your cooling system or affect its performance.
- Suitable for all types of vehicles: Whether you have a gasoline or diesel engine vehicle, K Seal works effectively on both types.
- Affordable: Compared to other permanent coolant leak sealers in the market, K Seal offers excellent value for money.
How to use K Seal Heavy Duty Permanent Coolant Leak Sealer ST5516?
Using K Seal is relatively easy and straightforward:
- Clean any dirt or debris from the radiator cap and expansion tank before adding the sealer.
- If your vehicle has an expansion tank, pour half of the bottle into it. Otherwise, pour it directly into the radiator.
- If your vehicle has an expansion tank, top it up with water until it reaches its maximum level. If not, fill up your radiator with water.
- Tighten the radiator cap securely and start your engine. Let it idle for about 20 minutes while keeping an eye on the temperature gauge.
- If necessary, top up with additional water until you reach your vehicle’s recommended level.
Things to consider before using K Seal
Before using any product on your vehicle’s cooling system, there are a few things you should keep in mind:
- K-Seal is not designed for use in motorcycle engines or two-stroke engines.
- K-Seal will not fix leaks caused by physical damage such as cracks or holes larger than one millimeter.
In conclusion
In my experience with various coolant leak sealers over the years, I have found that none compare to K-Seal Heavy Duty Permanent Coolant Leak Sealer ST5516. It offers a quick and easy solution at an affordable price without compromising on quality.
