A great way to buy your leaking radiator or heater core some time while you save $ to fix properly.
I have been using Bar's Leak on radiator problems for decades here and there. It's a very effective product and has saved me time and time again. Just keep in mind that if you keep adding more and more over a period of time to the SAME radiator the radiator will lose effectiveness and you will start to experience overheating. Bar's Leak is a temp fix to buy you precious time ;~) Use it, Buy yourself several months of car usage, maybe a year. And save during that time for a new radiator.

It worked great on my car.
This worked great on my car. I have an 18 year old car with about 177,000 miles on it and I want to hit 200,000 miles before I look for anything else. I was adding anti-freeze to the radiator about once a week. I used this and it fixed the problem. I don't know if the problem was in the radiator or one of the hoses, but wherever it was, it was fixed.

Was surprised...
In the automotive industry for 59 years. This manufacturer has been along for longer. I had stopped using it due to its consistency. A friend told me if their change in consistency. I ordered this product along with the usual brand. I have used the other for it will wash away in the radiator cleaning process. I had had issues with this brand actually plugging the core. The chunks were much larger, somewhat like small cat kibble. To my surprise it appears to be the same as my normal sealer only a different color and at one quarter of the price of my other brand. Both my customer and myself are very happy.
