(12 pack) Bar's Leaks Radiator Stop Leak - 6 oz.

Excellent choice! Thank you!

Seems to have stopped the leak.

had a slow leak on vehicle after replacing headgasket, heatercore and hoses replaced. Used this product and it stopped mystery leak.

This has to be the worst garbage that I have ever put into my car. I was losing fluid levels and overheating so I checked to be sure that the oil wasn't milky, inspected the hoses, changed the thermostat, flushed the radiator and the heater core as well as inspected the water pump but couldn't find a profound leak. At this point, on a short time budget, I put the Bar's radiator stop leak in the car. I was kind of grossed out by its appearance. It was thick and gloppy and I was a little apprehensive as I squeezed it out from the bottle and into the radiator but it was supposed to work according to the label and reviews, right? Over the course of the week the car started to be sluggish then difficult to start, then, all trouble broke lose at the worst time. Between work, appointments and regular daily life, within a 5 day period I blew 3 hoses before checking the thermostat again and found that it was completely clogged with the sludge that plopped out from that bottle. I eventually realized the root of my problem was a faulty radiator cap but not until after the costly repairs needed that were caused by this product. I am so frustrated that I fell for the "Magic in a bottle" theory that Bar's bestows.
