Tried other products with repair of cracked block with no success discovered this stuff and followed directions on can. Problem solved. I'm am so jazzed and recommend this product for coolant leaking into oil and exhaust leaking into coolant.

I have used this product for over 40 years. WATCH the video on how to use. It is a great product. Not to be used with ANY anti-freeze, JUST WATER and make sure the engine is hot/operating temperature. After you drain the system, let it set up for at least 2 days. This is the difference between this product and all the other crap out there. This is a good fix, not a band-aid.

This product really works at sealing a head gasket. Used it 3 years ago in my Civic and it's still going strong! Bought another one to stock it.

By the time the item arrived it felt weird. When I open it, it was thick inside it couldn't come out. If you see the picture you can tell that it looks disgusting probably even expired or defected. Not gonna buy this again :(

After shaking the can to get it ready opened and poor som liquid came out but the sealer stuff was hardened to the bottom of the can like it had been sitting for years. I know the stuff worked in the past that's why I ordered it but was not expecting the sealant to be sitting at the bottom rock hard couldn't even break it up

This is insane...i blew the head gasket so bad that when i open the oil cap that water was splashing out in my face...i used this an fallowed the instructions EXACTLY an itss been running perfect ever since....i drive hard and use my Ac all day and i havent lost 1 molecule of coolant at all...i drove from organ to los Angelas immediately after using this product and i go to side shows every weeknd with my car and still my 2 eyes have yet to see 1 drop of water on the ground nor have i had to add 1 oz of coolant yet...i would advise everybody use this even if you dont have a leak...its like a cheat code...
