Our 1992 Bluebird bus with its 6 cylinder diesel developed a head gasket leak. After installing Bar'’s Leaks Head Seal Blown Head Gasket Repair, the leak stopped. All the shop crew from Teen Challenge International of Mid America thanks Bar'’s Leaks for making a fine product. When you say professional grade, you aren't kidding.

OK, I never write reviews but feel compelled to do so here. My '02 Ram 1500 is my pride joy but a head gasket leak has it burning coolant, blowing white exhaust and getting worse by the day. After two mechanics estimated a $2,000 to $4,000 repair bill I had nothing to lose by spending $45 on your Blown Head Gasket Repair. I used the full bottle due to the large capacity and followed directions. In the miles I have driven since, I would have added nearly a gallon of coolant mix. I have not needed to add a drop. Tight as a drum so far. I was skeptical but this is simply amazing. Shame on the shops for not telling me to try this first. Thanks!

I want to start this communiqué with the following: THANK YOU, THANK YOU, and THANK YOU!!!!! I recently purchased a 1993 Toyota Camry with a bad motor. I replaced the bad motor with a salvage yard engine. Not long after the engine swap, I blew a two inch crack in a month old radiator and overheated the replacement motor. After replacing the radiator, I had zero trouble with overheating during in-town driving, but was overheating after 50 - 60 miles of highway driving. Without fail, I would stop to find the coolant boiling out to the overflow tube of the coolant tank. I replaced the radiator caps, thermostat, the water pump, and the fan assembly to no avail. I also used a cooling system flush product to ensure no rust deposits in the engine, I even had the shop that did the engine swap pressure test the cooling system.

After replacing a faulty cap, the system was holding pressure. The engine continued to overheat on the highway! I was ready to rip my hair out! I researched the problem online and concluded that I must have a warped head or other small crack. I researched a couple of products online that both required determining which cylinder was the problem and using their product to fix the issue. The biggest drawback was having to flush the system, disconnect the spark plug and fuel injector for the affected cylinder, then run the product through the cooling system. After cooling down, you had to flush the product out to the engine and allow the cooling system to stay open to the air to allow the product to "cure" for 24 hours. Only then could you add antifreeze and water and drive the car.

I am a fair backyard mechanic but it just sounded like a little more work than I really wanted to do. Not to mention being without transportation for a whole day. I decided to stop into a local chain parts store and check out their products. I have worked in the retail parts industry and was familiar with a block seal product called Blue Devil. I had heard good things about it but still had the dilemma of having to flush the system twice to use the product. Well, sitting on the shelf right next to the Blue Devil product was Bar's Leaks HEAD GASKET & COOLING SEALANT with carbon fiber technology. What appealed to me was not having to flush the cooling system twice to use the product, just add to existing coolant and follow some very simple instructions. Well, I bought the product and the Bar's Leaks worked like a charm. I have made three separate road trips running 75 MPH with the A/C blasting and had zero boil over or overheating of any kind! This carbon fiber block seal saved my bacon and my car! This is the best $60.00 I have spent in a long time and just reinforces my faith in the Bar's Leak name! Besides, with the capacity of my cooling system, I am able to get two treatments out of one bottle! This is awesome value for your automotive dollar! During this whole mess, I spent $75.00 on antifreeze alone! My sincerest thanks to the Bar's Product team, you have done an outstanding job for this customer and have ensured my loyalty in the years to come. Keep up the great work! I am a veteran and a proud American. I like buying products from the USA and will continue my patronage. I have already told several people how this worked for me and will continue to spread the good word! God bless and take care.
