Trust me, this is nothing like stop leak. We all know that most "pour in you radiator fixes" are bad for your cooling system. Blue Devil Head Gasket sealer, being a chemical based sealant, will not clog your system like other products that leave clumping particulates in your coolant. I can hardly believe it, but it actually worked. Watch the video see how to do it!
