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!

This stuff IS great ! B prepared to drive at least15 min with heat blasting to melt the pellets and circulate the material where it needs to go. This is all my van needs every 7 months or so no car repair needed, this is my go to.. It's the best thing for LEAKS or TO AID WATER PUMP GASKET or other gaskets and weak hoses IF ITS STARTING TO ALOW AIR TO get in which causes air bubbles, blocks cooling system, gets temp up above what your parts can handle causes damages when anything can boil or leak, not days breaks like that can EVAPORATE some flud leading to the same sort of problem. This does it all, seals, temp management, no need to flush out after, conditions and strengthens whole cooling system.

It works will get more

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. 🤦🏻‍♀️

So far I can't complain it came to the door I put it in the radiator on my RV ran it for a half an hour shut it off the leak has not came back yet. So far so good I'm very pleased. 👍

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 had a small leak in my radiator that would only leak when the engine was at running temperature and produced a fine spray. This didn't do anything - just wasted my time and a gallon of coolant. Ended up replacing the radiator and I'm glad I did because I'd have been concerned travelling any distance on a patch.
