Bar's LeaksHigh Mileage Cooling System Repair

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.

Works as advertised.

Fixed very slow leak in radiator

Definitely work I’ll recommend it

Put it in the radiator or the reservoir tank. Run engine for 20 or 30 minutes.

Kept having to add coolant to my reservoir. Thought this might work to stop the leak, but it stopped up the radiator and I had to replace it. Had high hopes for this formula, but I was disappointed.

I had a pinhole leak in radiator which was spraying all over under pressure. Poured it in radiator and it sealed up leak right away. 2 weeks it's still fine. I'll update regularlyAfter 2 weeks leak back with vengeance..this works for a short time

WORKED GREAT ! forgot I had drained my 1955 farmall tractor to replace the anti-freeze last fall. Started it up drove for about 5 minutes, and noticed steam coming from the radiator cap, and realized my mistake. I filled the radiator with water, and I had water pouring out the top and bottom of the radiator. (LOTS OF WATER). thought I would have to take it apart and solder it. After thinking about how much worked would be involved, I decided to try this product to get me back to work.10 minutes later, the leaks had stopped. HAPPY MAN - GREAT PRODUCT
