Pinhole leak in radiator--Alumaseal/Bar's Stop leak?
We discovered a pinhole leak in my (new) radiator. It's construction is similar to stock-aluminum core, plastic tanks. I was not satisfied with (2) all aluminum radiators from radiatorbarn, so that is not an option.
I would like to hear about people's experiences with such products as Alumaseal and Bar's stop leak, or any other variations. Ground pepper?
bars and alumaseal work good in a pinch, but you have to question if it plugs a leak what else does it plug ?
If it is new I would swap or get my money back.
I ran some bars in a truck for two years, with a radiator tank seeping
discovered a crack in the water jacket about 3 years ago.
what else does it plug up?
I dunno, but I haven't had a problem with the engine since (just everything else ). I was told by a Jeep tech it'd plug up all kinds of stuff. I saved a $5000 engine replacement (Jeep dealer quote) with a $2 tube of Alumaseal.
and...get a steel radiator. if you're not satisfied with the new one there is no need to keep it.
I had a pin hole in my radiator and used the off the shelf stuff from my local auto parts place and it worked well. No leaks...but I am replacing the radiator this weekend for piece of mind, plus I need a new water pump so I figure I may as well rip everything apart while I'm in there.

Never tried alumaseal, but I was on a road trip once with the family, and the radiator on our Suburban started to leak. Being that I was about 1000 miles from my house and tools, I stopped into a service station and bought some off brand radiator stop leak. Well, 6 months later I was replacing radiator, water pump, and hoses. That crap got everywhere and started plugging things up.

I've tried ground pepper, and it works well. But, it's only a short term fix. As far as alumaseal or bars leaks, I don't use either one. Bars leaks has small pellets in it that can plug up a TJ heater core. Alumaseal is somewhat better, but I prefer to have a radiator repaired before I use it.
if you can spot the leak , and its inbetween the fins on the metal part.. jbweld. it can be thinned as well. ideal way would be to pull it out, lay it on its side, tape the bottom and pour it inbetween the fins. I ordered a 3 core al. radiator a few weeks ago, and needed a "quick fix" its still holding up just fine. I didnt even thin it, or take it out, just smushed it in and taped both sides so it didnt drool out lol also.. i took a screw driver and pushed out a few of the surrounding fins so i could be sure i got enough in there to completely surround the fin. the whole process took about 8 min max
