Hey, I think i have a small pinhole in my radiator. I checked the lines and the seal on the thermostat housing and they all seem fine, so i am pretty sure it is the radiator. Does alumaseal really work or is there a better product out?

Thanks :beer:

Most of the products out there are just temporary patches until you get it really fixed. You have to remember how radiators are pressurized.

If it is just a "small pinhole" take it to a radiator shop, and get them to fix it right, or buy a new radiator. Or even a new one. A radiator for a YJ will cost about $100, and if you have a 2.5 you might as well put the 6cyl one on, they mount the same.

Heck Ya it works, It sealed up 1 big hole and 1 pinhole in less than a minute. As to it's longevity I'm still driving it. My buddy's radiator must have 4 or 5 tubes and it's still holding coolant.

Shit I that shit even fixes (temporarily) cracks in between the valves in the heads, just make sure you run the heather because it will clog the heater core hoses. I used it for about 3 months at a time, but again its not permanent.

I had a decent sized leak in mine too a few months ago. Put it in and not a drop has leaked since.

I agree that it does well in block cracks and in radiators with larger cores, but do not like it in smaller core radiators or heater cores. I use to work for a parts house and heard too much horror stories about Aluma-seal. I am a loyal fan of Bars-leak and the BG products version, plus these are flexible with the expansion and contraction of the cooling system.
Just my nickels worth.:)
