I drive a 96 ford ranger so to no one's surprise it blew a gasket and coolant was everywhere I was going to replace the radiator anyway so I figured why not save time and money and give this a try followed the instructions and it worked flawlessly not a single drop of water after I highly recommend especially if you have a old ford.......unrelated I installed the new radiator and it ran cold for a month and then the transmission went out so glad I used this stuff rather than get the gasket replaced. Lesson learned should have got a Chevy

Worked as intended Not a miracle fix but enough until we were able to have work done on vehicle.

I had a cylinder 5 misfire code for the past few months. I changed plugs, coilpacks, O2 sensor, and cleaned the injectors. I finally noticed water on my spark plug, that turned out to be coolant.I finally realized, it was a cracked head. The fix was more than the vakue if the car. I tried the Bars Leak and followed the complicated instructions. Now there is no more misfire and the car runs great again!

My Bounder RV developed a coolant leak. I think the water was going into the exhaust system as the combustion leak test checked out OK and there was never any water in the oil. But it would use a gallon of coolant ever 150 miles or so. So I decided to try the Bar's Leaks repair. I followed the directions. They say to not mix this with antifreeze. Because of the leak I had only been using water in my system for a while so it was fully flushed. Initially I wasn't sure whether it worked and I didn't want to waste a bunch of new antifreeze. So I decided to leave the Bar's leaks water mixture in the system and go on my 2000 mile vacation. I figured it would continue to plug leaks along the way. The repair seems to have worked because I didn't have to add anymore water to the system.Now that I'm home I'll flush out the Bar's Leaks and install some fresh antifreeze. I won't be using the RV for a few months but I'll update this review if there are any problems. But I got a good feeling about the repair and would recommend it to anyone in a similar situation as mine.

One reason I chose this product was for the $10.00 rebate which I did not receive.I did everything that was instructed to be done, after 10 weeks I contacted bars with no responseGood product and it worked but there was an offer that belongs to me.

Stuff works, has so far. You must however, make certain that the cooling system has been flushed of ALL coolant.

Because we are a major distributor for some products, we price very aggressively by sacrificing profit margin whenever we sell in bulk. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores. Unlike those wholesale to public membership clubs, we do not charge any membership fee. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Essentially, you are paying 10 times on shipping. We don't think that is fair to you. Why? Most of the time, shipping a 10 lb parcel does not cost 10 times of a 1 lb parcel.

Here is an example:

Quantity: 10	Quantity: 10
Total Shipping for quantity 10: $18	Total Shipping: FREE
Subtotal: $98 Saving: $102 (51%)	Subtotal: $200

Don't be shy. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Most of the time, we will match or beat their price, and give you a credit. If we lose to a competitor, it is our shame. We then know we need to work harder in sourcing to create values for you.
