Head Gasket Sealant
Head Gasket Sealant
How does the need for a block & cracked head sealant come up in the first place? Usually by overheating, which can be caused by a damaged head gasket, cracked head or a leaking block. Bar’s Leaks Block Seal Head Gasket Sealant eliminates this problem. This product contains a blend of aramid and refractory fibers, which provide the strength of a bulletproof vest and the heat resistance of fireproof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond, forming a hard, permanent ceramic-type seal.
- Seals Cracked Heads
- Repairs Blown Head Gaskets
- Stops Block Leaks
- Incredible Seal Strength
Stops all coolant leaks

DIRECTIONS
WARNING: Head Gasket Sealant is NOT COMPATIBLE with antifreeze and must only be added to the cooling system after ALL ANTIFREEZE has been flushed and removed.
DANGER: Opening the cooling system while engine is hot or running may cause severe burns.
DISPOSAL: Observe local laws & regulations. Where permitted, dispose of in sanitary sewer system. Never pour on the ground or in a storm sewer system.
NOTE: Protect from freezing.
- Engine must be cool enough to safely open the radiator cap. (This could take 30 minutes or longer). Drain and completely flush antifreeze from cooling system and overflow tank. Using a flush “T” with garden hose works best. If cooling system is dirty, use a good quality flush following manufacturer’s instructions. ALL antifreeze must be removed or clogging may occur.
- Shake well. Mix Head Gasket Sealant in a bucket or container with approximately 3 quarts of warm water. Pour this mixture directly into the radiator. If using in a small cooling system, including all 4 cylinder engines, mix ½ bottle of the Head Gasket Sealant with the warm water. TIP: If you do not have access to your radiator and vehicle has a pressurized reservoir, then product can be added to reservoir. If not then remove top hose where it connects to the top of radiator and install product in hose. Reattach and tighten clamp.
- Fill cooling system with water and reinstall radiator cap.
- Start engine, turn heater on hot and fan on high.
- Run engine for 10 minutes or until thermostat opens.
- Turn vehicle off and allow engine to cool. Allow enough time so it is safe to open cap.
- Top off (fill up) cooling system with water and reinstall radiator cap.
- Run engine at idle until normal operating temperature is reached. Continue running engine at idle for 15 minutes.
- Turn vehicle off and allow 45 minutes to cool.
- Top off cooling system with water as needed and reinstall radiator cap.
- Run engine at idle until normal operating temperature is reached. Continue running engine, but at high idle (approximately 1200 RPM’s for vehicles with a tachometer) for 20 minutes.
- Turn vehicle off and allow engine to cool for 1 hour. TIP: For vehicles with intermittent or very minor leaks, it is recommended to follow step 12 by idling vehicle for one hour.
- Remove radiator cap and drain system.
- Leave drain open and radiator cap off for 12 to 24 hours. If temperature is below freezing, vehicle must either be kept heated or immediately go to step 15.
- Flush entire cooling system and refill with manufacturer’s recommended antifreeze/water mixture.

You saved me a large expense
I purchased Bar’s Leaks Head Gasket Sealant part number (P/N) 1100 after receiving your email newsletter. In just a few days of using this product my 2011 Jeep Liberty is running great. No more misfires, or knocking, or antifreeze loss. I seem to feel more power in my drive too.
You have saved me a large expense, or possibility of getting rid of a vehicle that is still in great condition overall even having over 202k miles.
The reviews on internet were good when I researched my issue, and glad I went with your product. Would recommend 100%.

Still sealed after 4-6 months!
Not long ago, I was experiencing all the symptoms of a standard (although not severe, but more than “light”) leaking head gasket while leaving my hometown, headed to Memphis for a day trip. As much as I didn’t want to cancel the day trip, nor did I care to harm my motor, I decided to stop and grab a bottle of Head Gasket Sealant (1100). Followed instructions to the T, and not only did my large 5.4L V8 engine make it to Memphis with no issues, but it’s still operating as if nothing happened, and that’s been almost 4-6 months ago!

Bars head gasket sealant
I used this stuff and it worked great. I was scepticle at first. I used this stuff about a month ago. I had exhaust coming up through my expansion tank. It would cause my coolant to boil almost immediately. Well not immediately but after about 10 minutes. I followed the directions exactly how the bottle said and it worked. I see a lot of reviews about people putting this stuff in without flushing the radiator. I mean it say right on the bottle that its not compatible with coolant. Or it sounds like most people don’t have the patience to go through the steps completely. Or correctly. And then write a terrible review. This is an awesome product. Any negative feedback is from user error. There’s a lack of being able to follow instructions relative to every negative review. I have a beat up worn out broken 2002 Nissan Sentra. It was ready for the junk yard. This stuff did exactly what was advertised. Did a perfect job on fixing my problem. Its been about a month now with no negative consequences. Will use again.

I’ve read several of your testimonials for your Bar’s Leaks Head Gasket Repair and would like to add mine. Our kids in Vernal were having a problem with their 1999 Suburban overheating. They stopped driving it when they noticed that the oil color had changed. So on a recent visit, I checked it out. The oil was three inches high on the dipstick and looked like crème cappuccino. The 350 V-8 at idle sounded like a washing machine. The kids had been adding water to maintain the radiator fluid level and didn’t realize they were filling up the crankcase with water! I’ve always had good luck with your products when it came to radiator leaks. With a new baby arriving that day, the kids were in no position for a $1500 head gasket replacement. So we looked up your products online and then took a trip to the store for Bar’s Leaks Head Gasket Repair. I followed all the steps carefully, flushing the coolant system under idle, using a coolant system cleaner, removing all antifreeze and then adding Bar’s Leaks Head Gasket Repair and running as instructed. When I drained the crankcase, more than two gallons of fluid came out! It took two oil filters and three oil changes to get the oil to run clear. I let Bars Leaks Head Gasket Repair set up overnight in an empty system, and then added all fluids to specifications the next morning. Since then the Suburban has been running smoothly for several hundred miles in hot weather, and both the oil and coolant systems have maintained their proper levels and composition. I just got a call from another son-in-law who has a blown head gasket. Guess what I’m recommending!

I rarely take the time to write a manufacturer about a product, but I couldn’t let this pass. On 2/12, my car caught fire and was destroyed (fuel line cracked). Less than one week later, our second car blew its head gasket. I was devastated. How to replace two cars in one month? I don’t have that kind of money. While researching head gaskets online, I found information about your product. I read every blog I could find and decided I had nothing to lose. My mechanic advised against it. Although he agreed that my car, a ’92 Ford, was not worth the repair job of $1400, he told me that your product might destroy my engine. From my perspective, it was already destroyed, so I decided to give Bars Leak a shot. I flushed the radiator and added Bars Leaks Head Gasket Fix to the clean coolant. I’m now on week four, no smoke, no problems. The car is running as well as it ever did. Only problem is that if I idle too long (bank drive through lines…argh!), it will start to run too hot. I just need the car to last the next few months until I can afford to buy a second used car. My husband and mechanic thought I was nuts, but I can’t say enough about your product.

I used your Head Gasket Repair and wanted to let you know the results. Last night I drove back down to Souther California. 6 1/2 hours of driving at 65 mph about the whole way, over a couple of small passes…and the car had no problems. It didn’t run any hotter that what would be considered normal, even going over the passes, so no overheating. I had no smell at all in the car of coolant, and was running the heater, so I’ll assume that any leaks that may have been in the heater core were sealed. At the end, I didn’t have any smell of coolant in the engine compartment, and when I checked after the engine had cool, there was no loss of coolant during the drive. The car had normal power and got 27.5 mpg on the trip. This is as opposed to the trip up to Northern California last week, where the car overheated going over the Grapevine, lost 7 quarts of coolant, had the engine light flashing and the engine misfiring the entire trip, and then having it fail a block test, and being told I had a blown head gasket. After using your Head Gasket Fix product, all of that appears to have been fixed (I did have to replace spark plugs and wires that had pretty much melted in the original overheating) and on the return trip, the car ran as if there had never been any problems. So you have my thanks. You saved me probably $1200.

I know this is probably something most people would not do, but I believe in giving credit where credit is deserved. My girlfriend and I won one car, a 1995 Ford Contour, with a 2.0 – 4 cylinder engine. About 2 months ago it overheated and I believe the head gasket blew, or the head cracked and the car messed up. I have since lost my job due to the fact I couldn’t get to work. We live in a small Kentucky town in the mountains, I have no income now and we had to move in with my girlfriends mother. In the time that’s past since the car went down I’ve talked to a lot of people about the problem and most of them told me it would cost anywhere from $500.00 to $1000.00 to have the car fixed. Without a job I could not afford that at all!
About a week ago I talked to a couple of people about different products that work, like your Bar’s Leaks Head Gasket Repair and Block Seal and everyone I spoke with were so negative saying it would not work, but I scrapped up a $10.00 bill and went to an auto parts shop and I looked at the different products that they had for fixing my car’s problem. I decided to use your product, I guess because of the way your product advertised itself to me.
Well it worked! Our car is actually running better now than it ever did and I just wanted to thank you for being there and for having a product that really works.

One major problem with driving a 17 year old vehicle is that when a serious mechanical failure occurs, the dollar cost of repairs is no cheaper than a 2 year old car. My 1990 Mitsubishi Monter 3L V6 recently blew a head gasket. It had been coming on for over a year. I had been adding your older formula, the one with the pellets, and it helped for that long. Finally the decision had to be made: repair or junk.
I happened across your Head Gasket Repair, and for the price I thought what the heck, why not? Although I have never seen a mechanic in a can work before, what did I have to lose? I purchased the product, took it home and used exactly according to your label directions. I have since travelled over 7,000 miles and added NO water or coolant. No more white smoke when cold, no more dead cylinder while cold. I don’t know how long it will last, but I have enjoyed freedom from worry for that problem for over 5 months. Hopefully I won’t worry about it ever again.

Hi, this is not a question but I wanted to say thank you for your Bar’s Leaks Head Gasket Repair product. I have a 96 Olds Bravada. I bought this car a year ago for 4000.00. Within the last 2 months I have spent 2000.00 on ball joints and idler arm, replacing a leaking gas tank, alternator and battery. Its become a financial nightmare. This week after problems with my cooling system I discovered a blown head or intake gasket. After all the money I’ve spent already this was one of the most depressing situations I had to face. Upon starting the car antifreeze would pour out all over and the car would begin to overheat. Knowing the cost of this type of repair work and the fact financially I could not afford it, I went to our local auto parts store and read all of products on the shelf I bought yours.

I have a 1992 Ford Explorer with a 4.0L V6 engine. During this recent hot summer, I started to experience combustion pressures in my coolant system. I have talked to a few auto repair shops that said 4.0L Ford V motors are prone to this type of head gasket failure. This caused the coolant system to become over pressurized and would cause steam to blow out the thermostat gasket. Upon closer inspection, the coolant was foaming and bubbly. I was not planning on keep the vehicle very long but this issue made the vehicle not usable and to have the vehicle repaired by replacing the head gaskets would have cost more than the vehicles worth.
Bar’s Leaks recommended I try Bar’s leaks Head Gasket Repair. I had a local auto repair facility perform the installation of this product because of the multiple flushing and fillings of the coolant system but at the total labor cost of $102, it was far cheaper than having the head gasket replaced.
I now have a little over 2000 miles on my vehicle. It does not consume any coolant. It does not blow out steam from the thermostat gasket. It has made the car completely reliable in the hot weather and stop and go city traffic. Thank you Bars Leaks for saving my vehicle from the junk yard!

As a diesel engineer and petro-chemical engineer, having worked on many makes of cars, I decided to buy the Bar’s Leaks Head Gasket Repair for my 27 year old 280E that sprung a head leak.
Now I am not really the type that would not do the whole head repair myself, but as a mechanical engineer and car buff, I have come to the conclusion that my kids get fed up of the sight of my dirty hands.
So beyond believe I did it, after years of believing that these products NEVER work and it is all just marketing of a product. Well I was proven wrong, after all these years, having worked on all my restored cars from Astons, Lotus, Rolls-Royce and Bentleys and my 400I Ferrari. I went down to NAPA with my beloved 280E which is my daughters car, in search of the quick fix.
Well I was astounded. Your products certainly are reaching the claims that they make because after following the instructions I have no leak! So I called another long time mechanic that had a leak on the left bank of his 1980 Ferrari 400I and told him my experience. He did the same and BINGO NO LEAK.
I have forwarded your site to all my car club buddies, including my dad, who thought I was just lazy not do the head set change. Well from now on, I am going to be lazy because your products WORK! Thanks!

Often times in our business it is a difficult task to try to balance the need of the customer and the price of a repair. On the other hand, the customer needs to have something fixed on their vehicle in order to use it. Also, repairs on todays vehicles can be so costly that the customer can be hard pressed to come up with the money for the repair.
They had previously had a head gasket repair on their 99 Ford Explorer. The repair ran upwards of $1,500.00 unfortunately, the head gasket had started to leak again. The customers were faced with the dilemma of taking a loss on getting rid of the vehicle, they owed considerably more than it was worth, or spending another $1,500.00 to fix the head gaskets.
Neither of these were an option. Always skeptical of the mechanic-in-a-bottle type of quick fixes, we decided to give the Bar’s Leaks Head Gasket Repair a try. We were shocked by the results. It actually stopped the head gasket from leaking! Thanks to Bar’s Leak Head Gasket Repair, we were able to help a customer that would have otherwise not been able to afford the repair on their vehicle.
In addition, we were still able to make a sale. While not much as the repair itself, we were faced with the customer having nothing done to their vehicle and a loss sale. Bars Leak was a great alternative! We would highly recommend this product to any garage in need of an inexpensive alternative that works!

I wish to express my happiness over your apparent success with your product Head Gasket Repair. I have a Supra/Toyota 86 that had a head gasket leak when I bought it. I have taken the head off 4 or 5 times replacing gasket, shaving head, and checking for cracks but found none, but each time I return it and tried to run the car, 20 minutes later it ran hot.
A few days ago I stopped by for oil and noticed the Head Gasket Repair and being only $9 said what the heck, one more try before I replace the head. IT WORKED! Sirs, I am impressed. Thanks!

After charging me $980 to replace the radiator etc, the repair shop said the head gasket was blown and it would cost $1,950 to fix. I decided to try the Head Gasket Repair instead. Immediately fixed the problem. Well done Bar’s! A truly excellent product. Highly recommended.
