Can Bar’s Leaks HEAD SEAL Blown Head Gasket Repair be installed in existing antifreeze?
Yes, it is compatible with ALL types and brands of 50-50 mix antifreeze including yellow, orange, pink, red, blue and green silicate based & non-silicate based (OAT / HOAT) coolant. It also works great in systems containing only water. Cooling systems that are dirty or partially clogged, should be flushed and cleaned before usage.
Can it be installed in a diesel engine?
Yes, it works with ALL gasoline and diesel engines. This heavy duty formula works on aluminum and cast iron heads & blocks, along with sealing all other engine cooling system leaks better than a traditional stop leak. This includes repairing head gaskets, cylinder heads, intake gaskets, cracked blocks and freeze plugs.
Will this work in both domestic and import cars and trucks?
Yes, Head Gasket & Cooling Sealant will work in all types of water cooled vehicles.
How does this type of product work?
The special formulation contains a combination of antifreeze compatible sodium silicate sealing liquid & various size gasket sealing particles reinforced with Carbon Fiber which penetrate gaps & cracks and harden to permanently stop leaks.
What if I don’t have direct access to the radiator?
If you do not have direct access to your radiator and the overflow tank is pressurized, you can install in the tank. Otherwise remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.
Does Bar’s Leaks Head Seal permanently repair leaks?
Yes, it is a permanent solution for your cooling system leaks. What do we mean by permanent? It is not designed to be temporary, or a quick fix like other brands, especially those which do not use reinforcing fibers in the formula. Just like replacing a head gasket will not last forever, neither will Head Seal. But in some cases, our formula can even last longer than if the head gasket was replaced.
Do I need to drain my radiator after the leak has been repaired?
No, top off radiator and leave Bar’s Leaks Head Seal in the system for continued protection and drive vehicle normally.
What are the dosage recommendations?
One (1 liter) bottle treats cooling systems from 10 quarts (2.5 gallons) to 20 quarts (5.0 gallons). Use ½ bottle for smaller cooling systems from 6 quarts (1.5 gallons) to 9.9 quarts (2.49 gallons). For larger systems use 1 bottle for every 5 gallons of cooling capacity. In very small systems, use 2 ounces per quart of capacity.
How does Xtreme Cool™ make the vehicle run cooler?
The Xtreme Cool™ additive in Head Gasket & Cooling Sealant reduces the surface tension of coolant increasing the wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and leaks.
Will Bar’s Leaks plug my heater core?
No, Bar’s Leaks Head Seal will not clog your heater core, it is safe and effective. Note: If using Bar’s Leaks® Head Seal to stop heater core leaks, make sure you turn your heater
control to HOT. Some vehicles have a valve that controls coolant flow through the core and when on HOT it allows full flow.
I accidently added the Bar’s Leaks Head Seal into my gas tank, what should I do?
Bar’s Leaks Head Seal is only designed to be added to the cooling system. If the product is installed in the gas tank, the tank should be removed and cleaned out by a professional mechanic.
I accidently added the Bar’s Leaks Head Seal into my engine oil, what should I do?
Bar’s Leaks Head Seal is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine part to clean all of the parts.

“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.”

“We installed Bar's Leaks Blown Head Gasket Repair HG-1 in a '99 Chevy Malibu w/3100 V6 w/56,000 mi. on it to stop an intake leak. I was not sure it would do the job but holy cow this really does work. It's now been 3,000 mi. with no more leak at all and didn't plug anything. I've been in the auto repair business since 1951 and have never seen anything like this product. I would recommend it to be used on any car.”

“I purchased the Bar's Leaks Blown Head Gasket Repair in attempt to get a little more life out of my (winter rat) 1997 Jeep Grand Cherokee after a cooling system failure that nearly blew the engine and ended up resulting in a head gasket leak! I was worried about the expense but it turns out that this stuff really is a modern miracle in a bottle! I used it as directed and no more cooling or head gasket leaks, better engine performance, and the remainder is still floating around in there guarding against other minor leaks that might develop. Thanks for spending the research dollars to bring a product like this to market!! It was a life-saver for me!”

“Thank you for making this awesome product. I have a Mercedes 300E that got hot and warped the head some. Water seeped into one cylinder and I couldn't start it until I removed the spark plug and got all the water out. After using your product, 3 days later everything was back to normal. Now I don't have to pull the head off and resurface it. Thanks again!”

“I own a 2005 Nissan Frontier, my vehicle was having over heating and coolant loss issues. I was getting cylinder misfire codes, O2 sensor code errors and my coolant resolver was having pressure issues. After changing four O2 sensors, six cylinder coils and plugs, the spark plugs, the coolant reservoir and then I giving my vehicle complete tune up I was still having overheating issues. I then took my vehicle to a second repair shop and they advised I could try a bottle of head gasket repair before trying to physical repair the head gasket. I did my homework and all the repair head products clams to do the same thing. The reason I chose Bar's Leaks Head Gasket Repair over the other products because of YouTube video testimony. I followed the instructions on the box and they were the same as other people's YouTube videos. It fixed my vehicles over heating issues. I wish I would have used it before I spent all the money on my other parts. My vehicle has over 180,000 miles and I'm still driving if thanks to Bar's Leaks. I waited two months to give a full review. I put the product into my truck on July 8,2016.”

“I have a 1997 Ford Expedition 4WD with 5.4L engine. I discovered on a trip from western Colorado to Denver that I had a head gasket problem when we were stuck in backed up traffic on the interstate, in the mountains, just east of Vail, Colorado. Luckily I had a gallon of coolant with me and it took every bit. After returning home from Denver I begin to troubleshoot the problem and tried several different products with no luck. I was viewing the Bar's Leak web pages when I discovered this new product with Carbon Fiber. I had too travel to Glenwood Springs to get the product. Got home and used the product as instructed and it has lasted for 9 years. Thank you Bar's Leak for saving me thousands of dollars and allowing a hundred thousand miles of use of this vehicle. Less than $5.00 dollars a year. THANK YOU!”

“This product works!
I own a small pest control company that I started on a shoestring budget a year ago. My 2007 Ford Ranger (3.0 V6) began to smell like coolant from the outside of the vehicle. There were no visible leaks but I was loosing coolant drastically. I had a bad head gasket. I replaced my fouled plugs and used this product following the directions precisely...no more leaks, no more coolant loss. This product works! I NEVER write reviews but this product saved me over $1000 so I felt like it deserved a little praise from a struggling small business owner.”

“Had a combustion leak in head gasket on 2006 Chevy Equinox. Continual air bubbles in coolant, running water sounds during acceleration, and the smell of syrup from internal air vents. Vehicle has 195k on it but otherwise in extremely good condition. Decided to it was worth the try after seeing videos of others and viewing their results.
2 weeks later and still working great. Bubbles are gone, no more running water sounds, coolant temp completely normal and steady. I was hesitant about using this and now I wonder why I waited over a year to try. The one thing I recommend is follow the directions EXACTLY as written. If is says idle for 15 mins then allow 30 mins to cool, then do it that way. I did not deviate from the directions at all. As time goes by, I'll update results.”

“I have a 1998 Honda Civic LX 1.6 liter, that started to develop a periodic overheating problem. After some research, and some basic fixes (involving replacing a faulty thermostat control fan relay, engine belts and water pump) the issue of overheating was improved- but radiator fluid was still being pushed from radiator into overflow tank (I confirmed presence of exhaust gas in coolant). I should state that this effect was very minimal at speeds below 60mph and more apparent when driving above 70mph (and in mixed highway and stop and go conditions). In some cases (very high speed 80-100mph driving/followed by stop and go city driving) coolant was in fact blowing out of radiator cap and overheating severe, in particular before the fan control relay and water pump was replaced. I should also state that there was no "mayonnaise" in the oil or white exhaust plume even in the worst periods of overheating. It appeared the gasket breach was involving only coolant side, at least that is what I could tell.
As such, given the age of the car, and its use (generally local driving and some highway (and no, it does not need to be driven about 70mph) I decided to try this product, in hopes of avoiding near $2000 dollar head gasket replacement bill.
I watched the Bar's video and found that idling for 15 minutes (and longer) was no problem (with above described fixes to my car coolant system)- so I followed the directions using slightly more than half a bottle of the stuff, as recommended. I did this actually twice (I added the Bar's Leaks once- and repeated the 15 minute idle/cool down process twice).
I have observed as follows- At low speeds below 70mph, there is NO displacement of radiator fluid into overflow tank. There is no exhaust gas in the coolant, there is no overheating issue in even the most stressful stop and go conditions. I have also noted that, the radiator itself and especially the top of the radiator and cap, are "cool" (as compared to way too hot before using Bar's and fixing coolant system issues)to the touch, even after the normal type driving cycle this vehicle sees. There is quite simply no longer any overheating or apparent exhaust gas heating of coolant. Car idles fine, no skipping or no traces of radiator fluid being displaced into the overflow tank. All the engine oil has been replaced and again- no mayonnaise apparent at all.
So- I can say that (along ensuring that the operation of water pump and coolant fan and relay system) the Bar's has at this time resolved the issue. it has been about two months running fine (under the same traffic conditions, speeds and amounts of time driven that had previously caused overheating). I have NOT driven the car at speeds above 70-75mph (and certainly not above 80mph since). I have kept a close eye on the exhaust in coolant. I one recent occurrence I was essentially stuck in traffic after being on highway- for two hours- without any overheating issues or observed coolant displacement. Previously, this same driving condition would have cause rather severe overheating.
I should say that I was skeptical of this product, and expected little. However- given the results- so far- so good. I think the key here is to understand that this product can work, given assurance that the basic coolant system is properly functional, and that the head gasket breach is early enough and small enough that the Bar's fix can work. No cure in a can for fully blown head gaskets, and I do not think Bar's is stating as much.”
