Technical Alumaseal Radiator Stop Leak

I have a very small weep of radiator fluid around the lower hose outlet. I think maybe the pipe going into the bottom of the radiator got moved around when removing/refitting the lower radiator hose when my "car guy" was doing some work to realign the radiator in the shell. The car keeps cool and it is only a small amount of fluid that comes out.
He gave me some stuff called Alumaseal that is aluminium(that's how we spell it) that is an aluminium powder that you put in and then drive to make the product work. I am always concerned about stop leak products.
Taking the radiator off and back on again is a pain with probably a couple of hours off and same on again.Then it is an hours drive to my radiator man or maybe a bit less if I use a local guy.If I did this then I would get the radiator properly repaired and tested.
So has anyone used this product and give me a heads up.

 

That stuff works great, I used it long term and saw no bad effects.

 

Don't use that snake oil stuff unless you're planning on selling the car real soon. Do it right, do it once.

 

Alumaseal is better than Bar's Leak.... The stuff works OK. It won't plug heater cores like some other products, but may or may not permanently fix it. I did keep a rotten radiator in a beater truck going for about five years by using a can or two of this every couple of years, so it does have its uses...

 

I've also heard dumping a few s****fuls of black pepper works as a stop gap, and also a raw egg..... but I've never done it. Been using Bar's Leak since the 70's with no complaints.

 

I put Alumiseal in the radiator on my Boss Hoss motorcycle 5 years ago. Hasn't leaked a drop since

 

Alumaseal work really well.

 

I seem to recall hearing one major US auto manufacture uses Alumaseal or something like it in new production vehicles, or did at one time. Don't know how true that is. Before they leave the factory that is, to preclude any small leaks.

 

It should work fine for you. The parts stores used to sell something like that in a little cardboard tube.

 

I have used it with success in the past.

 

it works better if you desolve it in some warm water then pour it in the rad.

 

i had a cadillac seville with that pos aluminum engine. factory fix was stop leak in it because of coolant getting past the cylinder liners. it worked!

 

Alumaseal works really well, but in your case, it will be a temp fix. Reason why I'm thinking that is because if the pipe is starting to crack at the joint, the normal engine movement will continue to "reopen" it. Where alumaseal works best is like a hole in the core, and for that, it's put in and forget about it..

 

JCMarz X2. There's always enough time to do the job right. Anything else will bite you in the *** at the most inoppportune moment like in the middle of nowhere.
