how to use radiator stop leak

There are some sure signs by which you can detect that your radiator is leaking. A pool of green or other colored liquid under your car is one of those signs. Another common sign is your engine which will overheat during normal operation. Hopefully, there are radiator stop leak products to work on sealing radiator leaks. As the replacement of the radiator is a costly and time-consuming project, most of us prefer to use a radiator stop leak to solve the problem. Radiator stop leak is the easiest and most effective solution to seal leakages in the radiator. It seals internal cooling system leaks, external cooling system leaks, and gasket leaks. Also, it prevents future leaks. But, how does radiator stop leak actually work?

Radiator stop leak works in a very simple way. It seals leakages by using its filler particles, ceramic fibers, and sodium silicate while they are forced into the gap under pressure or creating a patch under high temperature. Though each type of radiator stop leak works in a slightly different way, the end result is similar.

How does it work?

Radiator stop leak is made of millions of tiny particles that travel throughout the pipes of the cooling system. But the working method of different stop leaks is not exactly the same. They have different working principles. Most of them use filler particles or ceramic fibers or sodium silicate. These three are mostly used components in the radiator stop leak. Let’s see how they work as a sealant particle.

How do the filler particles work?

The basic filler particles in the radiator stop leak are ceramic, metallic, or organic. When the liquid is poured into the radiator, these particles circulate through the radiator and are forced into the leaks when the system is under pressure. These particles create a temporary seal by creating a bond. But one problem with these particles is that once you flush your coolant or even top off your coolant, you may flush out enough filler to remove the seal.

How do the ceramic fibers work?

Ceramic fibers in the radiator stop leak work better than the filling particles. They use a micro-sphere Nano-technology approach, which can create a more fibrous patch in the radiator. They actually work under high temperatures. Once they are heated enough, they create a semi-permanent patch and stop leaking. Another thing better of this fiber is that it can withstand flushing of the coolant without breaking the seal.

How does sodium silicate work?

Sodium silicate is known as liquid glass. It has the melting point at around 212 to 221 degrees Fahrenheit. When the liquid circulates through the cooling system, it takes the containing sodium silicate in the hot portion of the engine. Once it reaches the correct temperature, it melts to form a hard seal. Sodium silicate requires temperatures up to 1,490 degrees Fahrenheit to melt again, so it creates an extremely strong seal. Usually, these types of stop leak last for a long time.

What are the uses of the radiator stop leak?

We only know about the leak fixing ability of the radiator stop leak. Besides this, it also can do some other useful stuff in the radiator. Overall, it can be used for a wide range of purposes. The uses are-

Stops external cooling system leaks

For sealing any external leak it reaches leak and travels between the holes, gaps, and cracks. They gather around the outer perimeter of the leak and builds an inward and effective seal. They create a strong seal without clogging the cooling system.

Stops Internal Cooling System Leaks

A radiator stop leak is the most effective for the internal cooling system leakages. Mixing with the coolant liquid, it reaches to the leaks in the cooling system. By the system pressure and temperature, the particles of the radiator stop leak bind or create a patch to stop the leaks.

Stops Head Gasket Leaks

Good quality radiator stop leaks are also capable to stop head gasket leaks. When the radiator stop leak particles burn after exposing to the heat of the combustion chamber, it forms a hardened seal in minor head gasket leaks. But for the larger head gasket leaks, you should use the Head Gasket Repair.

Prevents Future Leaks

Radiator stop leaks are also capable of preventing future leaks. They flow within the cooling system and are ready to stop both external and internal radiator leaks. Some of them are capable of preventing the rust on the metal of the radiator. As it can keep the metal better, the risk of leakage decreases.

Cleans the Cooling System

As the radiator stop leak contains millions of tiny particles, it can clean the cooling system by the particles. When they run all over the coolant, these particles can remove rust and dirt from the metal surface of the coolant.

Protects from Cavitation

Cavitation damage is caused by micro implosions formed by low-pressure voids from the water pump impeller. Some of the Radiator Stop Leak helps to break up the air bubbles before they can cause damage. 

Final words

To get the best result from the radiator stop leak, you have to follow the proper way of using it. Otherwise, it may clog or create the problem of overheating. So, use the best product in the best way to get the best result.
