This product really works so simple to use. My heater core had a leak and kept putting steam on the windshield after following the instructions, added to the truck water system, the problem has been resolved for now, and I know this is just a temporary fix, but still really helps, and saves money in the winter, cause I need heat. If I need to redo the process again I will, but its been 1 month and holding. The cost for heater core replacement $3200, this product $45, if I need it again, still worth it, it would take 75 times using this to equal the replacement cost, so, each and every other month, I will reapply the product, and roll with it. Great product for my vehicle.

Blue Devil works, but slowly.

I had some bad head gasket leaks, oil in the coolant, coolant loss, oil dripping on exhaust manifold, rough idle, stalling. Blue Devil Head Gasket Sealer has cleared up most of the problem. But it took a little bit of driving each day for several days. Anyway, no more oil in coolant, no more coolant loss. Rough idle improved but not entirely gone. Probably that has another cause other than leaking head gasket; still I'm hoping it will get better.
