Review on Bar'S Leaks High Mileage Cooling System Repair, 16.9 Oz by Ronny Welch

I drive a 2010 Ford F-150. I picked this up at a local auto parts store because I didn't have the money to fix a leaking water pump. The leak wasn't huge but it was definitely there. Shook it up, dumped it in the overflow tank, then ran my engine for approximately 15 minutes. The leak did not stop immediately and I assumed that either the leak was too large to be fixed this way, or that the product was faulty. A couple of days later, I was shocked to see that the leak had actually stopped. Perhaps it had not had enough time to set, or maybe it just needed to fully circulate through the cooling system.no idea. But it has definitely stopped the leak and it has bought me some time until I can afford to get the water pump replaced. Fantastic product and I'd definitely recommend it.
