I wanted to write and let you all know that I am so very happy that your product is one that works… I only wish that I would have trusted in this process a little while sooner. My wife’'s van developed a leak that came from the underside of the rear of her engine. After careful inspection by both me and a local repair shop, it was thought that either the intake gasket had failed or the head gasket. I spent two and a half days breaking the entire engine apart and replacing the intake gaskets and putting it all together just to once again see the leak when I was all complete. As frustrated as I was, I went to the local parts store and shared my frustration. They recommended Bar’s Leaks Radiator Heavy Duty Stop Leak. To be honest, I wasn'’t much of a fan of those stop leak products but I sure didn'’t want to spend another $300-$400 on replacing the head gaskets and the intake gaskets (of which I just replaced hoping it was the least of the two projects). I bought a jug of your product serial number 046087000472 and within 20 minutes of running the car, THE LEAK WAS GONE!!! I can’'t believe it!

It has been almost 4 months since I did this weekend project and still no leak! I just wanted to let you all know that you have changed my thinking about Bar's Pelletized Stop Leak. I will recommend your product to anyone who has a leak, before they repeat what I did and spend all that money on a wasted weekend of frustration. Thank you!

I am an ASE Master Technician and have 25 years of experience. Recently my work truck ('99 Ford Ranger 4x4 3.0) developed a severe coolant leak from a failed timing cover gasket (quite common on the 3.0 "Vulcan" OHV engines). I was a long ways from the shop and it was around 15 degrees out (not warm enough to work outside in my book). Filling the cooling system with coolant took about 5 minutes before the coolant was too low to circulate. I have never been one to use a stop leak product before, but I decided to give it a try. Im glad I did. Stopped up the leak like magic. Worked so well that i haven't had to repair it yet (a month so far). Heat and cooling system still working just fine. Thanks for a great product that delivers!

I guess this is not a question really, but a testimonial. I work in the fast lube industry, and deal with additives every day. When I had vapor and fog coming out of my vents in my '96 F350 with a Powerstroke Diesel, my heart sank, having replaced it less than 6 months ago with a new core.

I will admit, when the idea of radiator stop leak products came to mind, I doubted it would work. I don't really believe in pour in fix-alls just because of the additives I sell, I don't really believe in. I went out on a limb and got a bottle of Pelletized Stop Leak and poured it in the top hose, after dissolving the pellets in hot water. I poured it in and didn't expect anything to happen. Drove it for 5 minutes, and my windows were fogged up. I cleaned the windows and kept driving. Only a little fogging, and after 20 minutes it was done. Fixed! I couldn't believe it.

I would definitely recommend this to anyone I know. I remain skeptical of other "rebuilds in a bottle" but I would sure buy Bar's Leaks again. Bar's, thank you for making a great product that actually works. Feel free to post this as a testimonial. Love the product!
