Bar's Leaks 1199 Radiator Stop Leak Automotive Additive, Vehicle Type: Universal, 11oz

The product works but follow directions. The engine needs to be hot and circulating for the product to seal the leak. I used 2 packs of the product for my radiator. I have used this product before and for a small to medium leak it has always done the job. I am speaking of radiator leaks; as this has been my experience.

As priced online, the Bar's Leak was less expensive than at an automotive store. I should have checked to see if the price in-store was the same, but got caught up with trying to fine where to pick up the item I found. The website map is incorrect, showing to go to the west side of the store. I ended up going to the Return counter to ask for the item.

I have a 2002 Civic that had a radiator leak. Honestly, I poured half the bottle into the radiator, filled with coolant and no a single leak for going on 6 months now. Before this I was refilling every two weeks. I know it's temporary but it's working perfectly now. Well worth the money, highly recommend,

worked great! i noticed a small leak by my water pump as i poured this product into my reservoir tank and drove my truck around for awhile. the next morning i did not have to add water like i did the day before!!! it was so easy to use and the results were excellent!!

Had a leak in the radiator of my 2013 Nissan Rogue. Poured about half the bottle of this into the radiator. the other half into the reservoir. It did the tirck. worled as advertised. No more leaking. I dont know how long it will hold up, but for now the issue is resolved.

Automotive added really help when my raider was running out of water. I put the stop leak in the reservoir and start my truck after 15 minutes of driving the water seem to stop so it's a good good product recommend to anyone and everyone Thanks R

No sign of a leak after using this.

stop my leak for a bit , would recommend

Shook the product vigorously several times before opening. Product was clumpy and brown. Used this in the past and it was silvery and liquidly. After over a week, it did not stop my small leak. Now I would have to flush this out of my cooling system when I replace my radiator.

This stuff clogged up my cooling system. I'm still getting goo out of my reservoir. Stilll having a lot of car trouble because of it. Do not recommend.
