    Didn't work for me

    Reading the reviews on this website and others, it seems that this product works for some people, but not for others. It really depends on the location and size of your leak. I tried this for a radiator leak on my 2008 Town and Country and it didn't work, so I need to replace the radiator after all.

    Pros: Works for some people

    Cons: But not for me

    OMG it works

    I had a compression leak into the coolant system. Coolant (5 to 6 cups a day) was escaping from under radiator cap.

    I already had one vehicle down with a seized engine so I gambled with this very pricey stop leak. Six days later I have zero coolant loss. IT REALLY WORKS!

    The instructions say let the engine cool down(let the engine cool completely down to cold) and warm up at several points. Please follow the instructions exactly the stuff will start working much faster

    Pros: Really works

    Cons: Takes time

    This is a good product

    I have used this product on two of my cars. One is a 1992 Cadillac Seville with a 4.9 engine. This engine has a reputation for sweating and leaking water out the back through the block with virtually no fix. Over time it gets worse. The only fix I found for this prior to this product was to periodically put JB Weld over the spot. But, this only worked for a while then would have to be done again. I put this in the engine and the leak stopped and six months later, it is still holding.

    The second car I used it on is a 1999 Buick Le Sabre with a 3800 engine. This engine is notorious for a design flaw which allows for deterioration of the intake gasket and the upper intake itself. The heat from the EGR passage causes this and it starts slow and then blows. I put this product in this engine and it has been holding for 6 months also.

    This product is in fact a block seal which replaces older block seals that require the flushing, drying and waiting removal of thermostat and rinsing of the system before it can even be tested. 30 minutes and the job is complete. It is comprised of carbon fiber flecks which collect and dry upon hitting air. It is pricey, but well worth it!

    Pros: easy to use, works on variety of problems, Can put in antifreeze and leave in system without side effects

    Cons: may not work on larger leaks, cant use on systems which overheat quickly, pricey
