Blue Devil 38386, Liquid Multi, Blue Head Gasket Industrial Sealant, 1 qt

my truck engine was leaking coolant internally. Do not know the reason for the leak. it could be a blown head gasket or cracked head, does not matter. I can not afford to have it tore down at this time. needed to stop the leak till then. this stuff seems to do the trick. do not know how long it will hold so I can not really recommend it until then

This product works very well and w/ gas or diesel engines. Follow the directions as per the manufactures' instructions and make sure to "PORE" the contents into the system "VERY" slowly and it works.

I bought this to save my RAM CV engine. I used their cleaner, flushed the cooling system, and poured in the sealer. This stuff sealed my leak, saved me from having to junk the vehicle. Very good product!

Bet stuff ever saves you a lot of money but you must read all directions and follow them I've used this for years on several old cars and it's never failed me

Minimized van repair greatly. Major improvement. Would recommend!

This stuff is God sent!! Definitely worth every dime!

I dont know if the product is good or not because I didn't receive it. I got an Email saying that they delivered the liquid to my address but it wasn't there. So if you guys decide to order this liquid, just have in mind that you might not get it.

Followed directions to the LETTER. Did not do what it claimed to do. I should of just pulled the head and replaced the head gasket from the start. The money I spent would have went towards that repair.

product did not work following directions exactly.

The seal of the bottle was broken when I first trying to use it and I didn't notice it first when I got it. When I wanted to use it after 2 weeks after I got it I notice there was leaking around top then when I opened the cap I found out. Dishonest seller.
