Bar's Leaks PLT11 Pelletized Heavy Duty Radiator Stop Leak - 11 oz. Review

Stopped my current leak. Force you to put it straight into the radiator, not the expansion tank. I think some of the bad reviews are from people doing it wrong.

I had a small radiator leak which completely sealed it up after 30 minutes of idling. Since then I've driven the car a few times and nothing has leaked.

I had a main leak. It didn't seem to work at first, didn't seal immediately, but after about 3 days of running my truck the leak stopped completely. I suspect it will take some time for the pellets to melt and seal the leak. I had a burning smell for about a week but it went away. I definitely recommend this product.

This is actually the second bottle of this product that I have bought for my 2006 Explorer. She has at least one worry hole - maybe a second. I delivered the first bottle in mid-March and literally this week - on January 1st I delivered the second bottle. In that time, it wasn't even necessary to add more antifreeze or make it work differently than usual. MUCH cheaper than paying for a new radiation system. Also, it has more than 182k. Love it!

My 2006 Explorer (4.6L) found a radiator leak at 102,000 miles so I decided to flush and add coolant and then add this. Driven about 250 km with it, no leaks yet. For $6 I highly recommend this stuff. I will update this review later if anything changes. EDIT (10/13/2013): Just wanted to say that after a year and another 18,000 miles it's still not leaking. I'm impressed to say the least. EDIT (2/22/2016): So my radiator started leaking again sometime last year (and ended up replacing it…

Makes your coolant look like dirt but I use it on all the older cars I work on the cooling system. In my opinion this is great for preventative maintenance, especially for damaged systems which may have rust as they contain oil. lag and then take a couple of weeks to complete the process. Since then there have been no more problems with overheating. After a few days of idling I noticed a small stain from the radiator. A few months later I still haven't had to add water or replace the radiator…

I purchased a quality aluminum radiator with a lifetime warranty for my Jeep YJ. The cooler was scrap, was changed 3 times under warranty. The radiator always leaks where the fins meet the body. The company now charges $115 in shipping costs each time you ship a warranty replacement. I had enough and decided to try this product. The granules in this product were larger than expected and difficult to pour into the cooler, had to do it in a few uses to dissolve the product. I took the jeep on the

it's great! B is ready to ride in at least 15 minutes, with jet blowing melting the pellets and getting the material where it's supposed to be. That's all my van needs about every 7 months, no auto repairs required, that's my choice. This is the best remedy for LEAKS or WATER PUMP SEALS or other seals and weak hoses WHEN AIR ENTERS causing air pockets, cooling system clogs, temperatures beyond what your parts can handle and causing damage when something boils or , do not take daytime breaks as…
