Had a 4 cylinder Toyota 1.8 ltr engine that overheated with a warped head. Tried Blue Devil, KW, and K-Seal, they all overheated car and did not work more than a week. Had to remove thermostat and flush system with them all. Then tried Bar's as a last ditch effort. Did not remove thermostat, followed instructions and let sit for 24 hours after. IT WORKED! Combustion back, no coolant loss, and a daily driver for a year before getting rid of the car. Recommended!!!

I used on a Honda accord 2003. Had a small head gasket leak and this has sealed it up for now.

Works well

Llego a tiempo..

exlente producto lo aplique tomando encuenta las instrucciones y funciono 1000 lo recomiendo

Put in 01 Civic. No more coolant loss. 155k miles. Should run another 100k

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 workedat 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?

Perfect.

The price is so good, i like the idea

Habia probado con otros productos para el linkeo en el radiador y no sellaban completo como lo ha logrado este producto. Recomendado. Su precio es mas alto que el resto, pero el desempeo indica que no importa el precio, sino la calidad del producto.

no more engine light nor blown gasket symptoms after using this product. I ran 1000 miles without any issues.

It stops the leakage within a week and the power of my car has increased by 20.

worked like a champ

El producto es excelente tal cual se describe funciona al 100.gracias

After throwing away $70 on Green Demon purchase, I purchased this product it worked immediately.

Easy to use and works if directions are followed

Great Product would of cost me $3000 plus ... My heads now don't leak my mpg is like stock my MPG has almost doubled.I've wasted so much gas not getting this shops told me trans leak maybe talked to the shop they werent convinced Looked at my heads and it wasn't dry .Half a bottle would of worked .

09 sienna my friend drove without coolant for 60 miles after that it kept overheating white smoke out of exhaust.my Machenic said head gasket so before I drop the van at junk yard I decided to give one last try. I remove radiator cap and started pouring this whole bottle along with some new coolant and drove around the neighborhood,same thing happened van overheating and smoke coming from the engine so I parked it safely thinking this liquid didn't work.after 3 weeks I finally decided to check again and van temperature is the same no more white smoke.So glad this thing worked. do it the same way I didn't before you buy a new engine or have the head gasket replaced.$30 is nothing compared to new engine or new head gasket replacement cost.

I only check the car Few times and it's not overheating

Had a tiny leak in the head gasket. Did not do anything for the first try, however stopped the symptoms once repeated. Does not have enough for multiple times on big engines. Might wanna order the big size. Make sure to completely heat up and completely cool down engine and not take it to the interstate for first test drive.
