  • What if I don’t have direct access to the radiator?

    If direct access to radiator is unavailable and if reservoir / overflow tank is pressurized, you can install in 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 GASKET FIX 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. Just like replacing a head gasket will not last forever, neither will Head Gasket Fix. Millions of bottles have been sold since the product was developed in 2004 successfully sealing leaks for many years and tens of thousands of miles.

  • Do I need to drain my radiator after the leak has been repaired?

    No, top off / add coolant to radiator and leave Bar’s Leaks HEAD GASKET FIX in cooling system for continued protection and drive vehicle as normal.

  • What are the dosage recommendations?

    One (24 oz) bottle treats cooling systems from 6 quarts (1.5 gallons) to 16 quarts (4.0 gallons). Use 1⁄2 bottle for smaller cooling systems from 4 quarts (1.0 gallon) to 5.9 quarts (1.49 gallons). For larger systems use 1 bottle for every 4 gallons.

  • I accidently added the Bar’s Leaks Head Gasket Fix into my gas tank, what should I do?

    Bar’s Leaks Head Gasket Fix 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. Do not start or drive vehicle.

  • I accidently added the Bar’s Leaks Head Gasket Fix into my engine oil, what should I do?

    Bar’s Leaks Head Gasket Fix 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 apart to clean all of the parts.

  • Will Bar’s Leaks plug my heater core?

    No, Bar’s Leaks Head Gasket Fix will not clog your clean heater core, it is safe and effective.
    Note: If using Bar’s Leaks Head Gasket Fix 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.

  • “I want to take this time and thank you for caring about your customers. My car has been sitting for one year because I could not afford to fix it being a single mother and unemployed. No one mentioned your product to me until I did my own research. Wow! you mean to say I could have been rolling long time ago? Anyhow I bought the Permanent Head gasket for $30.00 dollars at Kmart and rushed home like a child with new toy. I was so amazed because the instructions were so simple. Not having to drain anything or tow my car to a shop. Anyhow you all saved me $2000 and not hearing from the mechanic say that other parts are broken. Thanks Bar's Leaks. Now I need to find a lubricate for my coolant sensor maybe, you will never know with all this advanced technology.”

  • “I just wanted to say that I am very impressed with your Head Gasket Fix. I had coolant leaking out of my head gasket and poured a half bottle of it in my radiator and the leaked stopped withing a minute after the thermostat opened. I was a bit leary of using a stop leak for fear of clogging up my heater or radiator but so far I have no problem with that. A 30 dollar bottle of your Head Gasket Fix appears to have saved me over a grand in repair cost.”

  • “I was in the middle of nowhere 300 hundred miles from home towing a car with my '94 6.5L turbo Diesel Chevy Blazer, I looked back and saw a huge white cloud, checked the water temp and it was at 260, coolant was dripping out the exhaust pipe. The belt had shredded, I hitchhiked to the nearest town bought a belt, coolant, and Bar's Block Seal & Head Gasket Fix, I knew it wouldn’t work especially on a diesel but I was not close to a garage or hotel, I followed the instructions and waited, IT WORKED! I continued on my trip and back home, I was really impressed, good stuff! It saved me a few thousand dollars!”

  • “I have a 1994 Dodge Caravan. The heat did not work and smelled like anti-freeze vapor, the engine would sputter, smelled like burnt anti-freeze, and generated vapor out the exhaust. My mechanic advised the car needed a $1,500 head gasket repair! Well, that's not happening so what do I do? First, I tried a product called Steel Seal, and that didn't work at all. Then I discovered your Head Gasket Fix on the shelf at one of our local retailers. I actually didn't expect it to work, but thought it was worth a try. That was 1,000 miles ago and my Caravan is running just fine now. The Heat works and doesn't smell like anti-freeze. The engine doesn't smell like burnt anti-freeze, and there is no engine sputtering, all this at 1/3 of the cost of that inferior Steal Seal product. Thank you Bar's Leaks, your stuff really works!”

  • “Bar's Leaks "Head Gasket Fix 1-Step" should be sold at church. It's a miracle. This past winter was hard on my 1998 Audi 2,8 V6. At about 215K the alternator went and the coolant pump/timing belt followed soon after. Probably caused by putting-off the coolant pump repair work due to money resources, the head gasket blew a short time later. With the head gasket leaking, but the coolant pump fixed, I was using about a gallon of coolant every 100 miles. My mechanic suggested trying a liquid gasket fix instead of a costly head gasket repair. I tried Bar's Leaks "Head Gasket Fix 1-Step" and it sealed everything up for about 2500 miles with no coolant added! At first I was easy on the engine and then, at the 2500 mile mark, I was moderately hard on the engine performance - particularly acceleration. Then the seal let go a little but still works! I am averaging about a gallon of coolant added every 2500 miles. The Audi has 227K miles now.

    The 800 phone number is in bold print on the container so I figured Bar's Leak was inviting a call. Tech support on two occasions was excellent. With freezing weather a few weeks away I plan to add another treatment and go easy on engine performance. Once again, Bar's Leaks has kept my car on the road for sure.”

  • “Thank you for saving my automotive life. Last week I had both of my vehicles in need of your products. My 1991 Toyota Previa van lost its head gasket, antifreeze in the oil and smoking like crazy. I used Bar's Head Gasket seal and 20 minutes later I noticed a huge difference. It has been a week and my oil looks like oil and my antifreeze level is perfect and she runs like a champ. My second car is a 2000 Chrysler van which sprung a bad radiator leak. I used Bar's Radiator Stop Leak and it has no more leak. Thank you Bar’s! You saved me from many thousands in repairs or a new car payment.”

  • “I used your Head Gasket Fix (works with all anti-freezes) and it saved my car. I was looking at a $1500 repair for a car that just wasn’t worth it. But for $20 your product saved my old car. Maybe I can get another 5yrs outta it now!!? Thanks!”

  • “I used Bar's Leak Head Gasket Fix not expecting anything. My mechanic told me that I had an internal and external head gasket leak on my 1994 Toyota 4 Runner and advised me to junk the vehicle. Within 5 minutes of adding your product, the steam out of my tailpipe stopped and the engine compression returned. I am just amazed and so is my mechanic.”

  • “I experienced a major intake gasket failure on my Chevy 350 causing the entire contents of the cooling system to empty into the oil pan during a short 5 mile drive to work. The failure was so extensive that the slurry found its way into the cylinders and air cleaner housing as well. Not looking forward to spending a Saturday tearing down the top half of my motor, I instead decided to try a liquid "Hail Mary" approach. Having had good past experiences with other Bar's products, I visited your website to become familiar with your entire product line and choose #1111 for this situation. To be honest, I didn't have high expectations for success due to the seemingly extreme condition I was using the product for. I am very happy to report that a single treatment with the product has sealed the failed areas. The operating temperature is normal, after 3 oil changes the oil is staying clean, and I have not lost any coolant. My advice to anybody considering using product #1111 is don't let the $30 price scare you into using a lesser option. Although every situation is unique, this product worked for this situation better than I expected.”

  • “I bought a $32 bottle of your Head Gasket Fix to get rid of a SES light on my 1997 Cadillac Deville with a 4.6L Northstar engine with 111,000+ miles on it. To make a long story short, it worked. The engine was stuttering or missing 15 seconds on a cold start up or 15 seconds after a warmed up stoppage of the engine and restart. I suspected that antifreeze/coolant was getting into the #1 cylinder due to a defect in the cylinder head gasket. The cylinder head gasket is very difficult to replace on this engine as the transmission has to be removed first. Thanks for such an easy and effective product.”
