Great product

This 23 years old Suzuki g16b engine passed 270 km or 170 miles and most likely over time the aluminum head suffered from corrosion. The mystical disappearance of the coolant began. No service company was able to determine the true cause .Here's what I did: to add 1 \ 2 Bar's Leaks 1111 (for small engine) directly to the radiator, I poured a similar amount of coolant from the radiator through the drain valve. Then I opened the heater, started the engine and it worked at 900 rpm for about 25 minutes until it warmed up to the temperature of turning on the radiator fan. I turned off the engine and drove the car only the next day. I closely monitored the coolant level every day and it kept disappearing but less and less every day. I compensated everything that disappeared and returned to the previous level so it was easier to control losses.Until eventually the disappearance ended!!!!. Thanks for Bar's Leaks 1111 and I hope this state lasts as long as possible. In a pinch I still have half a bottle left. :-)

It worked as it should for a small leak in my 2004 Mercedes. I noticed the oil was a bit milky colored so I changed the oil and bought a bottle of this. After adding this and following the directions the leak was sealed and I have not had any issues after 2 months is regular driving.

I was losing about a gallon of coolant a day, some of that was making into the crank shaft (not good) . I followed the directions and WOW ! No more loss of coolant! That was 2 months ago and it's going strong.

Misfire cyl one on 2011 prius 203000 miles. Toyota dealer said head gasket leak, low coolant. After 1000 miles still running good, 6 mpg better than before.

I haven't been missing any coolant/ antifreeze since I added this about a month ago. I was very skeptical about using it, but I'm glad I did in my 2002 Nissan Sentra SE-R...

Blown away, I thought why not! Instead of $2000 in engine repairs on a garbage 3.1 gm engine! This saved me from doing those repairs, for how long I'll get back and let you know. Just try it you'll love it!

it worked very well

This product worked just fine.

I did it on my 05 Dodge Neon and it worked. I drove with a blown head gasket for at least 4 months. I was buying 2 gallons of coolant a month. My coolant never mixed with my oil so I don't know how it would work for those people. But I do want to say u must follow the instructions exactly. I had good looking coolant in my car but still drained it and did a coolant flush just to be safe. Taking extra time and a little cash to do that is worth it compared to something going wrong and being out of a car. Just get some flush cleaner and some water. Run ur car for at least 15 min let it cool then drain it and put fresh coolant in. Leave enough space to put the bar leak in. I put half in my 4 cylinder then topped off with coolant. I personally started the car with the cap off let it run through and topped it off again then put the cap on and let the car idle for 15 min with the heat and fan on high. By 15 min I just reached to operating temperature and cut it off and let it sit till it's cold. I let mine sit for an hour but it was also 40 degrees outside. I topped it off and ran it again at 1200-1500rpm for 15 more min cuz I don't have cruise control. Then I cut it off and let it sit over night. I've been driving around and it's no where as rough as it was and the leak is gone. In a day or 2 if I see there is no leak what so ever I'm going to flush it out just cuz I want to personally. But please follow what it says and don't be lazy about any of the steps. I wanted to give a detailed review cuz I was very nervous about this product and I want everyone who uses it with a realistically fixable head gasket case to have a good experience.

good product

This stuff works great! sealed the blown head gasket on a Kia Rio

Impressed. No Problems

I used this on my 2004 Jeep Grand Cherokee 4.7 liter, worked as advertised, read the directions 3 or 10 times, follow the directions and it will work for coolant leaking into the exhaust system.

Excelente producto y buen precio

I cant begin to explain how helpful this product is in plugging leaks temporarily til the leak can be repaired!

21 year truck overheating and blowing antifreeze back into the reservoir either this stuff was going to work or head to the bone yard , happy to say still driving truck and running fine. Just amazed how good it works that was a month or more ago

Great product. It stopped a mild head gasket leak, and after a couple of days- eliminated the mild white smoke coming out my tailpipe. The key is strictly following the directions, and wait a few days for it completely work. If you properly diagnose the problem, and follow the directions without deviating- it works great! Highly recommended!

Help with the problem we had!
