Find out how to use a radiator to stop the leak and when you can use it effectively. Sodium silicate requires temperatures of up to 1,490 degrees Fahrenheit to re-melt, so it forms an extremely strong seal. Once it reaches the right temperature, it melts to form a tight seal. As liquids circulate your cooling system, it travels up to a leak in the hot part of your engine. Finally, sodiums silicates, also known as liquid glass, melts at about 212 to 221 degrees Fahrenheit. It may not be as durables as a brand new radiator, but it can withstand flushing your coolant without breaking the seals. Once heated, these fibers cure and form a semi-permanent seal. Instead, Ceramic Fibers uses a micro-sphere nanotechnology approach to create more fibrous patches in your radiator. Once you flush your coolant or even top up your coolant, you can pull out enough filler to remove the seal and create another pinhole leak. These particles bind and form a temporary seal. Fillers, whether ceramic, metal or organic, circulate through your radiator and are forced into gaps in your radiator piping when the system is under pressure. Heater cores can withstand leaks similar to a radiator and are much more labor-intensive to repair. The heater core is basically a small radiator inside the car’s cabin, which radiates engine heat for heat in winter. Stop leaks can be a very simple and inexpensive way to avoid major headaches Here are some of our favorites.Īlso, Read: What Is a Beater Car? | Who Should Get Beater Car? | Beater Car Benefits | Beater Car Downsides How Does Radiator Stop Leak Work?

If you have any questions please call CRC Technical Services at 80.Drain water then refill with fresh antifreeze/water solution.After curing, flush cooling system with water until it runs clear.With radiator cap and drains open allow drained cooling system to cure for 24 hours.

Stop engine, let cool, remove radiator cap & open drain.Replace radiator cap and idle for 20 to 30 minutes.

Note: If the engine overheats, turn vehicle off, allow engine to cool, top off with water then restart. Radiator cap, detach upper radiator hose and add mix directly into hose.

Add mixture to radiator, not the overflow tank.

Remove the affected spark plug(s) & disable fuel injection to affected cylinder(s) before next step. (Tip: Use a 1-gallon milk or water jug.) Note: If coolant is leaking into a cylinder remove and check spark plugs for an orange/white crystal or fluid appearance. Small engines may require less than 3 quarts of hot water mixture.

Shake can and mix with 3 quarts of hot water in a separate container.

For best results, flush cooling system with K&W® Cooling System Flush #401320. Turn off engine and drain cooling system. Idle for 5 minutes to flush excess antifreeze from system.

Close drain and refill radiator with water.

DISPOSAL: Observe local laws & regulations. Set heater control to maximum hot position.

With engine cool, remove thermostat (see manufacturer’s specs) and radiator cap.

Not following directions EXACTLY could cause severe engine damage. DIRECTIONS: Read entire label before using this product.
