It in-turns allow your vehicle to run long enough to get to a proper repair shop.

Radiator Sealant

However, while it’s an aftermarket additive, some car manufacturers use it on new radiators to help improve the seal between new radiator components. If you’re wondering how to use the sealant, don’t worry it is not difficult to use. This article will unveil how to use the Product, how it works etc.

Radiator Sealant

Having knowledge of how to use Radiator sealant is an essential skill if you are concerned about one day being stranded along the highway with a cracked radiator.

There are different types of Radiator sealants in the market today. However, these products have the same basic component. Below are common components found in most radiator stop leak additives;

  • Ceramic fibres and particles
  • Sodium silicate
  • Aluminium, copper and iron particles

However, you mustn’t see all of these ingredients in a single radiator stop leak product. Some include other ingredients that target other common radiator issues or assist these particles and fibres in forming a seal.

How Does Radiator Sealant Work?

Every radiator sealant works in a little different way. But the end result is similar, filler particles, ceramic fibres, and sodium silicate all attempt to seal by hardening and solidifying where the leak is occurring.

However, another area where this product can help is with your car’s Heater Core. A Heater Core is basically a small radiator inside the cabin of the car, it radiates engine heat for heat in the winter. These heater Cores can suffer leaks similar to a radiator and are much, much more labour-intensive to repair.

Fillers, including ceramic, metallic, or organic, circulate through your radiator and are forced into the gap in your radiator piping when the system is under pressure. These particles help to bind and create a temporary seal.

Furthermore, ceramic fibres use a micro-sphere nano-technology approach to create a more fibrous patch in your radiator.

The sodium silicate, also known as liquid glass, melts at around 212 to 221 degrees Fahrenheit. As the liquid circulates your cooling system, it reaches a leak in a hot portion of your engine. And when it reaches the correct temperature, it melts to form a hard seal.

Fill the radiator  and Allow the Car to stay Overnight

The last step is to fill the radiator with a 50/50 mixture of water and coolant to top off the cooling system. Allow the car to stay at least 12 hours so that the radiator sealant can set up properly.

Important Considerations

Not all problems are radiator sealant problems. For you to determine whether or not to use radiator sealant, there are things to consider in a pinch or an emergency situation, radiator sealant does exactly as it is supposed to do, which is to stop the leaks.
