I must say I am thoroughly impressed

I recently used Bar’s Leaks Cooling System Repair to fix a leak in my car’s radiator, and I must say I am thoroughly impressed with the results.

Not only was the product easy to use – simply pour it into the radiator and let the car run for a bit – but it worked quickly to seal the leak and prevent any further issues.

I noticed a significant decrease in the temperature of my engine after using this product, which indicates that it is effectively repairing and improving the cooling system.

Overall, I highly recommend Bar’s Leaks Cooling System Repair for anyone experiencing leaks in their car’s cooling system. It is a reliable and affordable solution that will save you time and money in the long run.

Worked in one use

I really like it, worked in one use. Highly recommend this item for small leaks.

I highly recommend this product

The Bar’s Leaks High Mileage Cooling System Repair Additive is a great solution for older vehicles with high mileage. The 16.9 oz bottle is easy to use and can be added to the radiator with no need for special tools or equipment. After using this product, I have noticed a significant decrease in coolant leaks and my engine runs cooler, it’s a great way to extend the life of your older car. Overall, I highly recommend this product to anyone who owns a high mileage vehicle and wants to prevent costly repairs.

What an amazing product

What an amazing product! We use these in busses and it stops all the heater core leaks and radiator leaks! There are about 4 heater cores on busses and I believe if all 4 were leaking they would all seal up! Thank you for an amazing product!

I cannot thank you enough

Hello, first I have to say that you are life savers. Words cannot express how thankful I am to you for your product. I am Lori and have not a clue about cars. I have a 2014 Chevy Cruze, and every time I would drive it, I had to put water or antifreeze in it and the temp gauge was teetering the danger zone every minute. Had to constantly keep an eye on it, drive with heat on and window down.

I stopped at my mechanic’s one day. I lifted the hood and he looked from about a foot away (because he was working on another car) and said “it is a cracked cylinder head”. I was devastated, I cried for 2 days. I only have 4 payments left after 7 years and I am attached to my car. He said it is not worth fixing it. So, I have to make it last until it’s paid off in Feb. Or pay someone to take all the parts off and part it out. Sickening.

Well, I Googled my problem and Bar’s Leaks came up. I went to AutoZone to buy your product. The guy that worked there said if it was a cracked head, it would be smoking out the exhaust, a milky residue would be around the motor and or you would have only been able to drive it for 2 or 3 days. There isn’t any smoke, no milky residue, and I have been driving it for 2 weeks. He thinks it is the water housing. So I bought the Cooling System Repair part number 1150.

It was so easy , just poured it into the coolant overflow and let it idle for 15 mins. WOW! It did not have to put in a drop of water after the 15 min idle, it was not ready to overheat. So happy. I have driven it twice since then and still have not needed and water .. and it is driving so much better. When stopped at a light I cannot even hear it running, just like it was when it was new. Simply amazing! I tell everyone about all your products. Not many have heard of them like myself so they are very interested. Thank you from the bottom of my heart.

Does exactly what it says

Works great. Highly recommend.

2 years later, still no leak

I used your 2-part Cooling System Repair #1150.  I bought a 15-year-old Ford Ranger with 135,000 miles. The water pump gasket had broken down, I used this product and 2 years later there is still no leak.

Got me to my campground, fixed overheating

I had a radiator leak in my 1983 Nissan Sentra while heading out on a camping trip. Halfway to the campground, my car started to overheat. I got to (then) Kragen’s Auto. I picked up a bottle of Bar’s Leaks cooling system repair, topped off the radiator with coolant. Made to the campground and back home with no issues of overheating.

Live saver

HEY BAR’S LEAKS!  YOU GUYS ARE LIFE SAVERS! 

COOLING REPAIR GOT ME OUT OF A PINHOLE RADIATOR LEAK IN MY PICKUP UNTIL I COULD GET A REPLACEMENT INSTALLED! 

Keep Up the Good Work!  Thanks Again!

The only product I will use

I have used Bar’s Leaks Cooling System Repair (#1150) as well as other Bar’s Leaks products on various vehicles for about 50 years. It is the best and only product I will use.

Recommended!

I have an older Subaru Outback. One day a few months ago, I noticed my temperature gauge was almost to the top. A mechanic friend had shown me a trick of turning on my heater to the max, which made the gauge go down some. I immediately drove home. That night I looked for (or had?) a $10 off coupon for any Bar’s Leaks product.  

The next day I took my car to get antifreeze topped off. Right after I went to auto store and used the coupon to buy Bar’s Leak Cooling System Repair, product number 1150. I then had to wait a few more days or a week until there was enough room to add it to my radiator. My friend then checked it out and following the directions, put it in my radiator. 

It worked and I have not had any overheating problem since! I love this and another Bar’s Leaks product I used with my previous car, a Chrysler, which also was leaking water into my oil, I think. That was also an amazing product which I bought because of a rebate associated with it. Now, I will always use Bar’s Leaks and I continue to recommend it to family and friends.

Bar's Leak Cooling System Repair.

Bar’s Leaks Cooling System Repair is absolutely amazing! A leak developed while I was about 15 miles from home a few weeks ago. I had water with me and was able to find water along the way to get home. Toward the end of the drive home, the engine was leaking about 1 gallon per mile. That’s a substantial leak! A few miles before I arrived home, I stopped at AutoZone and bought two bottles of Bar’s Leaks Cooling System Repair. After two and a half days of driving and keeping the radiator filled with water, the carbon fibers slowly did their magic. The leak has absolutely stopped!!! Thank goodness for Bar’s Leaks! I now have some breathing space to allow me to determine if I’m going to repair the leak myself, pay someone to do it or obtain a different vehicle. As I’m retired and on a fixed income, the breathing space Bar’s Leaks has given me is welcomed.

The engine cooling system temperature is absolutely normal. The heater is working normally. The transmission cooler within the radiator is functioning normally. I can see no adverse reaction to the Bar’s Leak Cooling System Repair.

I’ve become Bar’s Leaks greatest advocate! I’ve posted a testimonial on my Facebook page. I tell total strangers about it. If I had a big bumper sticker I’d put it on the tailgate of my pickup.

The vehicle is a ’97, GMC, Sierra 2500, 2WD with the 5.7 liter, Vortec engine. The leak appears to be coming from behind and underneath the alternator on the passenger side of the engine. As I’m getting no coolant in my engine oil, I’m thinking the leak is coming from the intake manifold only. As the Bar’s Leaks has relieved me of a stressful burden for the time being, I’m going to step back and take a breath before I dig into the source of the leak.

THANK YOU BAR’S LEAKS!!!!

Magic!

I don’t write reviews unless I am very impressed. My oil cooler on my 2011 Dodge Avenger started leaking gallons of coolant. Needless to say, my mechanic quoted $800.00 for a full repair. This product took care of the problem for under $10.00! I am a lifelong fan now! Thank you for this wonder product!

Bars cooling repair

Honestly I’ve used tons of stop leak products in the over 100 vehicles I’ve owned. Bar’s Leaks hands down is only one to date that did as they claimed. Am planning to use it on my low budget work truck to solve any issues because I work them to death. Thus far a leaking water pump gasket on my 02 5.3 Tahoe perfect fix without costly loss road time. I had 3 holes and a massive 3 inch slow leaking crack in my ’00 Silverado 5.3. Fixed all of it. Beat it to hell and never an issue from cooling system.. Will be using oil leak and trans leak formulas on budget truck I prior mentioned and will. Glady continue to update with it as well as mention how happy I am with this company’s blends that truly stopped what others failed to do prior.

Cooling System Repair- Worked Like a Charm!

Bought this product as a ‘”hail mary” before I dropped $250 (plus labor) on a new radiator for my 2006 Ford E-350 van as the radiator developed a 1 inch crack in the plastic portion along the top. To my pleasant surprise, the crack was sealed within 5 minutes of running the engine, just as the bottle claimed. I have driven the van countless miles with outside temperatures reaching 105 degrees and it is showing no signs of failure. Great product!

Great Product! Instant Results!

Used it in my 00 Silverado due to a heater core leak. Windows would fog up from the steam coming out of the vents. Drained some coolant to make room and poured it in. Ran the engine and wiped the windshield. Saw results after 5 minutes.

I had a leak in the radiator of my car and I used your product and today saved a lot of money. Before that, I have to buy a gallon of coolant every week and now I don’t buy coolant any more, I forgot when was the last time I had to buy it. After that, I bought your products for engine and transmission and used them. My old car is working quiet and it is saving gas, I don’t know the exact quantity but I know that I am saving money in gas. I am very happy with your Cooling System Repair (part 1150) blue and black product in the clear double sided bottle. You guys are the best, thanks again.

I had a substantial drip coming from the water pump. Your product was able to seal it after a 20 drive. Thank you for a great product.

Let me preface by saying I don’t know much about cars. I only know that I’ve had horrible luck with them. I’ve done a lot of work and maintenance on my Ford Escape 2005. The first time it was overheating, was because the fans were broken. After I got them replaced, the car ran good until it got a leak somewhere in the reservoir/tubes to the radiator. For months I had to keep dumping coolant/water into the reservoir EVERY SINGLE TIME I needed to get to work or even just go down a few blocks cause it would start leaking badly after just a few minutes of putting it in

I tried for weeks to find the leak but could never find it. I was skeptical that the Cooling System Repair (1150) was going to work, but I tried it at the recommendation of a friend. I am happy to say that it definitely works. In my case my car is still overheating but at least a lot less faster, and I haven’t had to add any coolant or water for a week now. Just remember to SHAKE WELL!

Tried today on a 2004 BMW 325ci. I had a radiator leak and almost paid $300+ dollars to replace the radiator. I saw this product online, called my mechanic and asked his opinion. He said, “why not?” I bought it for under $10 at Walmart. Followed the directions and have been driving all day with no more leaks. Seems to be working GOOD! Leak has stopped!

Used this for unknown leak in the top of my girls’ ’98 Crown Victoria engine. Worked great.

I have a 1989 Jeep Wrangler with a small leak in the top half of the cooling system. I would constantly have to top up the radiator with antifreeze. So get this, I was in a store looking to get a phone and we happened to get talking about our cars. The woman helping me advised me to try the Bar’s Leaks Cooling Repair. I put it in and to my surprise it fixed the leak. Thanks to the woman in the store and especially to Bar’s Cooling Repair. The stuff is magic!

I never write companies usually. However the experience I have had as a single dad keeping an 18 year old Nissan Xterra on the road merits this letter.

I had a steering pump leak that was going to cost $550. I was adding fluid every other day. I cannot tell you how many $5-6 dollar bottles of fluid I added to the reservoir – always the cheapest before I decided to buy the most expensive (your product), and see what that would do… That was 2 years ago, I never have had to add a drop since, and never paid for that repair, It “aint broke” so I don’t fix.

I started to have a coolant pump leak. No big deal, right? I can swap out the pump, I got tools… then I learn the pump is timing belt driven (i.e… Im not messing with that in my driveway) and it’s going to be $600 to get that done. Stressing about when/where Im going to be able to pay for that repair… I brainstorm maybe the company (you guys) that made the awesome product that for $12 FIXED my steering pump makes something for coolant leaks… I go back to AutoZone and sure enough you do… It took two bottles, but now, the leakage is gone, car runs great, never overheats. I check the coolant level daily but never a drop in the level anymore… You guys are AWESOME!!!

In 2 years, you saved my family over $1,150 (for 3 bottles purchase maybe $40 bucks outlayed) that we didn’t have to spend, I will recommend your product to everyone!
