I replaced my ps braket today and noticed one of the screws that hold the plastic cover over the radiator wasn't screwed in all the way so i screwed it in. On the way home I was smelling that wonderfull warm antifreeze smell so I watched my temp gauge as I was coming home never went over like 120-130 I poped the hood and there was antifreeze on the right cooling fan. So I unbolted the top of the fan to invesigate behind it.

Aparently the srew that was used to hold the plastic down was too long and I punctured the top of the radiator core. I'm wondering what your opinions are on using the alumi seal not the stop leak I know stop leak makes more off a mess of the coolant system then anything. This looks like a new radiator that is in here but I can't get ahold of the guy whom I'm buying the car from to see if its under warranty :-(

 

Only thing I'd put in there is the Bars leaks stuff. Little gray bottle that says something like Factory Installed. This was developed for GM to use in Caddys with aluminum heads when they first started this and couldn't get the gaskets right. Dealers still use the same stuff in a GM package for many warranty repairs instead of actually working on the engine. Pretty cheap stuff at about two bucks a bottle and it sure seems to work the times I've used it. Probably depends on how big the leak is, but this Bars stuff won't clog up anything.

 

well that stuff didn't work I'm trying some waterweld made by jb weld some epoxy stuff hardens in 20 minutes much better then the damn actual jb weld 15 hrs the screw made too large of a hole it basically cut open the whole side of the 3rd row down the small channel the coolant passes through. :-( Hopefully this stuff works i have a gtg to go to at 5 in grapevine

 

do not use any of that stuff it will haunt you in the future will start to clog up the system and will have to replace everything heater cores rad. flush out block if you can just dont use it see it happen before not good stuff just end up paying more at the end

 

Probably time for a radiator shop. If you can take out the radiator and take it in they'll cut the tube out and solder over the openings in the tank, not a lot of money for this I'd think.
