Man....A hose clamp from my FMIC was just touching my rad, and over 6 months it wore through a core, leaving a small hole.
I dumped a tube of prestone sealent in, it's like a damn cement powder. Well, My rad is vary clogged now. Overheats quickly, and flows very poorly.
Question- how the hell can I fix this? Any fluching chemicals?? The problem is, anything that will clean the sealent will probably re-introduce the leak... maybe I'll fix it with something else after.
What to do.....
I'm worried about my freakin heater core now too, it might be clogged up as well.
I'm guessing I can just solder the hole... or use epoxy or something. Hell, I fixed a Tbird Rad with bondo and it held untill I sold it!

So what would realy flushj the crap out of it? What chemical?

 

Wow that is a sticky situation. I cant think of anything that wouldn't screw things up worse.

What was this prestone sealant supposed to be used on? Is it made for radiators?

 

Yep... radiator stop-leak...
Radiator stop-flow!!!


I can fix the hole using other means.. just wondering if there is anything out there that I can soak inside the rad and will eat all the stuff out....

 

i would go get your radiator rodded out.
