SAVED ME $$$
I had nothing to loose as i got a $800 quote to fix.I had a internal coolant leak, bubbles in the overflow, smelling coolant , and idle was all over the place. Mechanic told me HEADGASKET..1996 Honda. You must follow the directions, I added 1/2 bottle to my radiator slowly and shook up bottle between pours. Started car and let it idle for about 20 min.Let sit for about a hour. Popped radiator cap off and filled with coolant. Car started kinda rough, but it immediatly cleared up and runs better than ever. I put 638 miles on it so far no problems. Follow the directions and this should take care of your problem.
Most Liked Negative Review
Only made things worse
Used it exactly as instructed on my 98 Subaru Legacy. It did nothing to correct the overheating problem, but it did noticeably clog the heater core. For the money, it seemed like a reasonable thing to try to get a month or two of normal driving before I come up with the money for repair. The first thing I noticed when I got into the car was that heater was blowing cold air. The car overheated some 5 minutes into my trip. As I was pulling over to let it cool, the upper radiator hose blew off. I had some coolant in the car, so I refilled and tightened the rad hose. Let the car cool for a bit, then turned around to go back, and the upper rad hose blew off again. The radiator cap was new from the dealer, so couldn't have been that. Definitely would NOT recommend this product, as my car was ok to drive short distances before I used it. Now I can't even drive it to the repair shop.

Works!
I can't believe it! I didn't expect it to work, but since it came with a 30 day warranty, I figured I'd give it a try. I added it to my radiator, let the engine idle for 15 min, and an hour later it was running perfectly. I tried driving it up hills, I drove it on the highway and in the city. No matter what I did, the temperature gauge needle stayed perfectly in the center and even the white smoke is gone. This little bottle saved me at least $1,000. Thank you very much Bars Leak!

Works great if you catch it early
93 acura integra was blowing white smoke that smelled like coolant. pulled a plug and it was drenched in antifreeze. definently a bad head gasket. before I was going to rip the engine apart I decided to try a leak repair additive. drained a little coolant and put in 70 percent of the bottle. followed directions and car runs and idles perfect. no smoke, no smell. made a huge difference. Took half an hour to put in and for [$] bucks it is a great deal. it helps if you catch the bad gasket early. i did not have an overheating problem yet but i def would have if I waited much longer. also this stuff is so convienent because you don't have to drain the coolant system like the other leak fixers.
Bottom Line Yes, I would recommend to a friend
