FAQ:

Q: How does a liquid glass cooling system sealer work?

A: Liquid glass refers to sodium silicate, which creates a glass-like coating internal to the cooling system to repair leaks. Open the radiator cap to break the vacuum. Slide the coolant drain bucket under the front of the vehicle.

Q: Which is the best sealer for a cooling system?

A: One such product like this that is still readily available is Irontite Ceramic Motor Seal. Sometimes referred to as “liquid glass” this is used to coat the walls of the cooling system. Filling in cracks and metal porosity making a “smooth as glass” coating that not only seals but also promote better coolant flow.

Q: What kind of sealer do I need for my radiator?

A: Unlike a typical radiator stop leak product, a cooling system sealer works to fully coat and seal your cooling system all over. This kind of technology has been around since the 50’s or maybe even longer. One such product like this that is still readily available is Irontite Ceramic Motor Seal.

Q: What kind of coolant can you use with liquid glass?

A: Park the vehicle on level ground and allow the engine to cool completely. Liquid glass, in itself, is compatible with all coolant types, including standard green coolants — which already contain silicates — and newer organic acid technology, or “OAT” coolants.
