i say nothing is impossible, i need help

This is a hard one and im not much on giving up so easy. i have a heater core that is pluged up with that crap barrs leak, and i would like it out so my heat works again. I was wondering if there is somthing i can flush it out with? For you guys that r gona ask how i know its barrs leak bc i talked to the guy who owed the truck before me and he told me he put it in there instead of putting in a new rad. when i drained the fluid i saw it in there i hate that stuff!!! Any help would be greatley appretiated.

 

I have heard of boiling it (completely submersed in boiling water) but I don't know if that will actually work or not. Bars-leak is powdered aluminum, right? So you need something that will dissolve aluminum while leaving the steel and tin and lead of the heater core alone. Not sure what that would be.

 

Bars is an organic compound. I don't know of anything that will remove it short of having it rodded out. didn't say what truck, but new cores are relitively inexpensive.

 

This isn't the aluminum one...some patent wonder material that expands. My thought is to see if you can get hold of prouduct safety sheet, required Federal document...cannot remember proper name. That will give clues on material and so suggest ways to kill it.
Since you can see some of it...try small drops of nasty chemicals directly on it so you can see if there's any reaction suggesting the stuff will dissolve more rapidly than your gore; lye, HCL, etc. If it were aluminum, lye would likely do the job.

 

I dont think you will get it out.May need to have it recored or just get a new one.

 

The MSDS sheet may provide answers, however the only thing that I know of to remove it is to replace the core. You could back flush the core with about 60psi and see if that works, however be careful as the standard hose beads are good for only 60 psi, any more pressure and the hose will come off.

 

Bruce I think this is what you were thinking

Material Safety Data Sheets known as MSDS

 

That is a great idea i will look on there website and try to get ahold of someone that can speak english and have them get me the safety sheet thank you.

 

I figured i would have to recore it but i thought i would give this a shot you guys have the answere for everything there r so many great minds on here.
