Irontite Ceramic Motor Seal - Engine Cooling System Sealer for Head Gaskets, Radiators, Leaks, & Cracks - Prevents Corrosion & Rust, Improves Cooling Performance, Stops Overheating & Coolant Loss

Seals most anything i've come across, has to be a serious crack in block or head not to seal.

This works and works good, you just have to make absolutely sure you have all the rust gone and it be clean as possible before using.

Just what I needed

I used this product but it didn’t work out. My engine was consuming about a quart of coolant per week so I must have had a bad head gasket that was leaking into a cylinder or possibly two at this point yet I had no overheating issues. I flushed my system per the manufacturers directions used the product as directed. Maybe my head gasket was too far gone for this to work. I just didn’t work in my application.

Met expectations, great product.
