Bar's Leaks Head Gasket Fix

This stuff is absolutely AMAZING!!! I really didn't think it would work bcz it did say for "small" leaks, (mine was NOT small) but with a $1,500 estimate to fix my 2006 Chrysler Town & country with 128k miles,(def not worth it to me) I wanted to try this product first before I broke down to buy a newer car. I was so skeptical since there were mixed reviews, but most were positive so I ordered it. First off my vans "symptoms" were massive coolant leak (over a gallon a day), over heating, oil mixing with coolant, heat only blowing out cold air. I did not have white smoke blowing out of tailpipe or milky film on oil cap or steam from radiator. The coolant leak (with oil mixed in it) and temperature reading HOT within 4-5 minutes of driving, & engine driving rough we're my biggest issues. My husband's friend is a mechanic, so I know he was being honest, did find the HG leak also.. it would have cost alot more to fix had we brought it somewhere else. The $1500 was a favor..but still too much for an older van.. anyways, so I got the product, & my radiator was empty bcz it all leaked out (but it does say u can add it with coolant already in the radiator/no need to drain out) so I poured the whole can in while engine was cool, then topped it off with antifreeze & squeezed on the hoses to get any air out. I started the van & left it running for 20 minutes with heat & fan on HIGH. I Could still see it leaking underneath but not nearly as much (wait it gets better!) So I let engine cool again & topped it off with more antifreeze, then took it for a slow 20 min ride around town with heat still on high.. it was NOT overheating! Heat was HOT again! When I got home & shut van off, I looked underneath and the leaking had completely stopped!! You don't need to do this next step, but I went ahead to get an oil change on day 12 & added one container of the"Bars leaks engine repair 2 part formula" for added protection (not sure if the stuff really works good or not but I liked the reviews & figured it could only help) I could not believe this stuff in a can did all of that so easily! This stuff is great! 5 stars from me! I saved so much money! I am now on day 16 and everything is still going great! No issues at all. I am still a little bit skeptical on how long it will work for, but I've read that some people got another 50-70,000 more miles out of their cars after using it before they had to use it again!.. so I am definitely a believer in this product! I'll see how long it lasts. If any problems arise I will be sure to come back on to post about it..but for now all is great! Van is running better than it has in a LONG time!!👍

It is no secret that GM has thousands of unhappy customers due to bad design of intake manifold gaskets, look it up on the web. After having the intake gaskets replaced three years ago they went again, they last about three years before blowing again due to bad gaskets and the effects of DexCool. I parked my vehicle trying to decide what to do. After much internet research I decided to tr{ this product. I am very pleased to say it works and is well worth the price. I do not know how long the fix will last but at least I can use my vehicle again, if I get another year of driving out of it I'll be happy. Again, it works. As an old broken down "wrench" I would have torn into it when I was younger but am not going to go through $2700 repair every two to three years. Update, 3/28/2012 Vehicle still running with no leaks or loss of coolant. You will need to keep it clear of your radiator cap so coolant can pull back from the overflow resivoir. This stuff works, look at the reviews here they aren't fabrications. Update, 10/22/2012 Still running just fine. Arizona summers find all sorts of weak spots in your cooling system, none arose this past year or summer. The coolant loss situation I faced was as bad as any I've read about here or other sites so it's not like it was minor. Maybe I am lucky but this product has given me use of my "family hauler" vehicle for just short of one year and another 5K miles of around town use. Update 12/15/2012 Well the leak fix popped last week and it's back to sucking coolant into the intake manifold. I will flush the cooling system and try the Bars Leaks again. I got just over a year of vehicle use with it so if you get results like this it's worth it. Update 1/21/2013, Weather was nice today so I added another bottle of this product ran it for 15 minutes while temperature held steady. Upon cooling down and checking fluid levers I drove eight miles with temperature holding right where it should. If past performance is going to repeat I should be drivable for another year. Update 08/09/2013 vehicle still drivable through another hot summer, even days up to 114 degrees. Would not of course take a long trip in it but for around town use it's holding up. Your case may be different but if your vehicle is old enough to have virtually no trade in value and need something to get you to and from work it is worth a try.

Scenario: 2003 T. 4Runner burning coolant through bad gasket, replaced radiator and somehow the aftermarket radiator cap cannot hold pressure to suck the coolant out from reservoir tank, driving 4-5 weeks car will overheating with 30-40 floz coolant loss that i have to add-in. Did some research and went through most of the reviews here are Amazon, decided to give this product a try as my last resort or i will have to replace the head gasket for a few $Ks which dont make sense for a 215,000 mile car. Go as directed on the bottle, pour in the whole bottle for v6 engine while "engine is off and cooled overnight", now after 3 weeks i poured in the product, i only have to add in 2 floz of coolant to radiator today! Amazing! It seems to stop the leak no more coolant loss! I will check back in 4 weeks to see how much coolant i have to add to top off by then. But the result looks very promising.! Updating @ 11/23/22, After i used this product and replaced another radiator cap and checked every month on coolant level, seems like the new cap works and the radiator will suck coolant from the reservoir tank as normal and the coolant level only reduced a tiny bit every month when checked. So i went from checking every month to checking every 3 months and not really much coolant lost! This Bar's Leaks saved my engine! I have been driving this 4 Runner for 2 more years so far and not having any overheating or burning coolant issues. THUMBS UP! Update@12/12/2025, engine is still running smoothly everyday. Checking coolant reservoir level every 6 months and only find about less than 1 inch in reduction. Excellent product that worked. I will definitely recommend this to everyone but hope I will not have to "buy it again"~

It's still working 3 months [Edit: 4 months ( 2012-12-17)] after I used it on my civic, which had a leaking head gasket. My mechanic said it would be a 1100 fix (woah!). He suggested that I use a liquid sealer instead. I did a search on Amazon for "head gasket sealer" and happened upon Bar's, and boy, am I glad I did! My first application wasn't successful. My car ran hot again after only a few days -- possibly because I attempted a 1000-mile drive to Yellowstone from Cali a few days after I used the product. Most sources I've researched say to *go easy* on your drives (don't rev it up too much) after using the product for at least a couple of weeks to allow it time to cure. So, after my second attempt, I took care to not drive my car too hard for the first two weeks or so. Also noteworthy is, on my second attempt, the coolant was almost empty when I used the product (on my first attempt, the coolant had been full). This might also be a factor in the successful use of the product the second time around. The takeaway from all this is: To give Bar's the best chance at sealing your head gasket, (1) drain your coolant before using this product (despite the instructions saying it isn't necessary). There are coolant flushing kits such as the Prestone AFKIT0 Prestone Universal Flush and Fill Kit that you can use to remove the coolant. (2) Go easy on your drives for a least a couple of weeks after using the product. There you have it. I hope this product works as well for you as it did for me. Good luck! (I will update this review periodically to report back on how Bar's is holding up.) [Update 2012-12-17] It's been 4 months after I used Bar's and that needle is holding rock steady where it should be. The coolant level, as far as I can tell, is the same as it was when I topped it off 4 months ago. I've already put 11,000 miles on it since I used "Bar's Leaks Head Gasket Fix." All signs point to this product working as a permanent fix as claimed. I'll update this review in a couple of months or when Bar's no longer works, whichever comes first. *fingers crossed* [Update 2012-12-28] Crud. My car overheated again yesterday when I was making a 250-mile drive. On this last trip, I had to rev up my engine to over 4000 rpm a good part of the trip (I usually shift gears between 2500-3000 rpm) but revving up the engine is hard to avoid when my underpowered (109 horsepower) car needs to climb some steep hills. It seems that the Bar's Leaks won't hold up on long, hard drives. I'm extremely disappointed, but still, I've had a good run with it the past 4-1/2 months. I'm going to give it another go. At 22 a pop, it's still better than shelling out over a thousand for a car that's reaching the end of its lifeline anyway. Product rating downgraded from 5-stars to 4 stars.

So my 2004 Audi A6 with 204k on it had some minor milk shake looking oil the last time I changed it. Not much but enough for me to be aware of the sign. For the last couple of year the check engine light would come on and stay on until it was cleared. I have also had challenges getting it to pass state inspection for the last several years. My mechanic insisted it was a leaking intack manifold vacuum leak and I disagreed. Then the car began to have a random misfire from time to time and the misfire was very inconsistent so I was thinking it could be a faulty coil or fouled plug. The check engine light would come on every 50-100 miles and I would reset it with my code reader. Then the clear sign of a blown head gasket of white smoke and low antifreeze show up. I have owned the car since new and honestly it is not worth the investment of a new head gasket as this is now my spare run around town beater car. So knowing I was buying a BS product that no way would resolve a blown gasket or warped head I thought what the heck do I have to loose? Junk man or a magic potion. Well a month later and about a 1,000 miles….no misfires, no check engine light, no white smoke and as crazy as it sounds the car has more power. I guess this magic potion worked…at least for now but i was very skeptical and say it is worth a shot of you have the early signs of a blown head gasket. How long will it last? Who know?

Used this product in a 2001 Chevy Blazer 4x4 with the 4.3 engine. Engine had been losing coolant slowly at first then faster. Saw no leaks and no white smoke. Warmed the engine about 5 mins, shook the bottle vigorously and poured it directly into the radiator while the engine was running. Let the engine run at idle for 15 minutes then took it for an easy test ride to get the rpms up and better circulate the product. Did not go over 30 mph. About 1/2 mile away the engine shut down so I pulled into a driveway. It would not restart. Called the tow truck. The mechanic said the coolant and this product had been sucked into the compression chamber through the faulty head gasket and then circulated throughout the crankcase. Coolant and this product filled the crankcase 3/4 of the way up the oil dip stick. All of the internal bearings have been scored by this product. Now, the cure is a $3000 rebuilt engine install. Thanks a lot Bar's Leaks. Update: After being without a vehicle since the last week of Dec 2018 I got my Blazer back from the mechanic's yesterday with a used replacement engine in it and it seems to run fine. Bar's Leak also clogged up the heater core and radiator and they had to be replaced. This whole fiasco has cost me $3,508.07. Again, thanks a lot Bar's Leaks.

Holy cow guys, for perspective, I only bought this to try and buy extra time. My car is a 1996 Toyota Tacoma 2.4 L4 I bought from a coworker last second so I could keep my job for $2000. I drive around all day from 8am to 9pm so you can imagine the pressure on it. I got stuck in traffic when to coolant ran out and by the time I got to the store the headgasket had already blown. It couldn't drive more than 500 ft with the heater on without overheating. Poured the stuff in and I let it idle for 30 minutes. It actually started overheating and I was worried I'd messed it up. Also it had used about half a gallon of coolant in that 30 minutes, but that may be a separate issue. And it worked as if there bad never been an issue. Been using it for over a month now. Well actually, there was one incident 2 days later. After I had driven to my first job I found it smoking and halfway to my second it started trying to burst out when i tried to take off the radiator cap. It also looked like the stuff backfed into the reserve at one point. But I mean, it worked fine other than that. So just use as instructed and something they dont tell you: for the first week, be overly cautious. Keep an eye on the thermometer, take breaks if it gets hot, and keep the heater on if you have to. Edit: Went back to the same frequency of overheating. It's been a little over a month. I guess it's what I expected. A little disappointing. Though $30 for a months usage beats fixxing the actual problem considering this was a junk car. Gonna buy another bottle see if that gets me more time. In conclusion. Use if you don't care about the car. Don't if you do care.

worked so far.great product.little high priced.

Lo compré para un fiesta 2008 el cual había pasado agua al motor, funcionó perfectamente, un producto un poco costoso pero que vale la pena.

Item same as described fixed the problem.

This stuff actually worked for my old Jeep 2007 Wrangler JK with more than 260k km (V6 3.8L). I had a leak in the timing chain cover gasket and also an other leak at the intake manifold gasket. Followed the instructions on the container and no more visible leaks after only 1 day of running the product. Also, my "Long term fuel trim" for Bank 1 and Bank 2 used to be around +12% and they are now under 4% at idle. I usually don't have a lot of faith in "magic potions", but "Bar's Leaks 1111 Head Gasket Fix" did a good job so far for my V6. Used the entire bottle for a 12 Liter coolant capacity, the stuff is kind of a bit thick and has an orange colour with copper flakes inside.

Me soluciono el problema que tenia, sello bastante el paso del agua al aceite y al cilindro. Me quito el humo por consecuencia de la falla del empaque de culata. Por ahora me da tiempo para hacer una reparación mas adelante.
