Temperature Warning Light?

Drove 2500 miles now after what appeared to be a weeping waterpump. Was leaking from lower side of pump about 3 quarts came out when I stopped to get gas. Put this in with 2 bottles drinking water and drove 500 miles home. 100 degrees out AC on all the way. Coolant still full. Have driven 2000 more miles since and hasnt leaked a drop. Waterpump seems solid and doesnt wiggle so maybe just dried seals from sitting for months during covid. Will keep an eye on it but this is some miracle stuff. Waterpump and belt and coolant sitting in garage so now just waiting for it to stop working. I may be waiting a long time. We will see Update May 2022. Waterpump finally went out in driveway but let me take 3 x 2000 mile trips with full AC on and 100 degree temps outside Gave me lots of time to buy parts and tools and fix it in my garage when it blew. Excellent product

Works! I used it months ago to stop a radiator leak on my 2007 Saturn Vue, I pour it in the engine coolant surge tank, it fixed the problem.

Had just purchased a used 2006 Honda Civic as a second auto and sure enough the block cracked at the water jacket spewing the whole contents of the coolant overflow reservoir in 10 miles. This manufacturing defect is a known problem so much so that Honda extended the warranty to 10 years. Didn't help me of course as i bought it in 2022. So in goes the Bars System Repair. Why not ? Nothing to lose as a replacement block costs many times over the value of the car even if I found a worthy replacement or whole engine from a junkyard. What do you know? It worked!! My leak has slowed to a very manageable 2 oz. , maybe less a week. Since I check my oil every week, it is a routine check anyway. I have 3,000 additional miles since and the result far exceeds my expectations. The coolant temperature has not changed from it's normal range one bit either. I dare say maybe a little less! As the only fix for a cracked block is replacement, (even welding on aluminum is temporary at best), this product is genius! Congratulations to the chemists at Bars. NOTE: I recommend mixing with distilled water in a gallon jug first as one of the components is very viscous and gets burped out somewhat by air getting displaced from the radiator by it.

Definitely work I’ll recommend it

after three bottles on my 88 audi a-4 leak is sealed!

Used it as a preventative treatment and it ended up ruining my car ! Clogged the whole system

I know I have a hole in my radiator, my car is old, replacing it isn’t worth it. I was adding 4 cups of coolant and 4 cups of water every six weeks. After a month this is holding, in that time my coolant is still within the cold fill range. The first I noticed is I haven’t had any rough start ups since, it may have plugged some head gasket leaks when the block is cold.

After reading many reviews I decided to give this a shot since my radiator was leaking for a couple weeks from an unknown location. After purchase I used it in the reservoir and to my surprise the leak continued again for weeks. I also noticed that my radiator was no longer pulling coolant from its resivior. So I decided to take a peak and noticed the gunked up the hose going from the resivior tank to the radiator. And soon after I found the leak coming from a small return hose. So after finding this I flushed the system and replaced the hoses. So in my instance the Bar,s Leaks did not work for my but it might for you. Just be sure where you are leaking from is fixable with this.

Stopped the leak great

Que buen producto, mi auto tenia unas pequeñas fugas ya se le habia cambiado la bomba y goteaba, desde que le puse el producto, a la fecha no he vuelto a llenar los Niveles de refrigerante, un gran producto, lo recomiendo utilizado en un MB C200

Excelente producto resolvió las micro fugas

Not a bad product my issue requires replacing parts. One of the better leak seals I've used.

Sello bien la fuga, lo llevo usando por más de dos meses y continúa funcionando. Definitivamente lo recomiendo
