Bar's Leaks PLT11 Pelletized HD Radiator Stop Leak - 11 oz.

I own a 2003 Ford Ranger four-cylinder. My radiator developed a slow drip. But don’t let a slow drip, fool you! Cruising down the highway my engine started to overheat and I had to pull off onto the shoulder as this slow drip rapidly drained my radiator! Not wanting to spend what could be thousands. I spent a few bucks on this product with nothing but amazing results! I could not access my radiator, so I dissolve the product and poured it into the reservoir as instructed. It did take a couple applications but now I have utmost confidence that I won’t have to pull off the highway again and it has completely sealed the leak! Thank you, thank you thank you!

worked wonders lol

Decent product. I did have to use 2 bottles to get lasting results.

Not big on leaving reviews but I am very big on reading them. I looked for reviews about this product sealing leaking freeze plugs. I didn't see any so I wanted to leave one for others who may be wondering if it will do the job . I followed the directions on the bottle. I did put hot water to dissolve the pellets as they kind of stay behind for the most part while pouring it in. Now for the moment you were waiting for. On my 1998 Chevy Blazer this stuff sealed the leak within the 10 minutes! I could not afford to have the motor lifted to replace the plugs, I am so excited 🥳💃🤸‍♀️🥳 I know this may be a temporary fix in the end but I don't care I can go to the grocery store. Wood hoo😁 THANK YOU Barrs for an amazing product at such a bargain! You have another satisfied customer💯 wish I would have thought to do a video before and after. 🤦🏻‍♀️

Note: This is not going to fill any gaping hole within your radiator. Rather, if it's 'perspiring' or dripping in in various areas, this will provide at least a temporary hold. Some folks have say years, but I can't attest to that as ours is too worn beyond fixing (ie; a gaping hole). Only downside is that you may need to dissolve the pellets with water a few times before you're able to empty the product into your radiator fully. Otherwise, a quality product that's worth a shot if you can't replace right away!

Yes, it will stop leaking. But if you use too much, it will clogged somewhere in the pathway the coolant runs. For my case, the heating coil, now my car has no heat.

I bought what was a high end all aluminum radiator with lifetime warranty for my Jeep YJ. Radiator has been a piece of garbage and replaced under warranty 3 times. The radiator always develops a leak where the fins meet the body. The company now charges $115 for shipping every time you submit a warranty replacement. I had enough and decide I would try this product. The pellets in this product were bigger than expected and were difficult to get them poured in radiator, had to do it in a couple applications in order to dissolved the product. I took the jeep for a half hour drive on the highway and let it sit overnight and not a single drop of coolant. Product worked great and no signs of the radiator tubes being clogged.

I followed the instructions exactly. It turned my antifreeze into a muddy-brown color and did not stop a pin-hole leak. With the car not running, I'm still loosing about 2 ounces of anti-freeze every week from the freeze-plug that this was suppose to repair.
