wondering if this would fix rad problem

chewy-tuna · 2 Mar 2013 at 19:30

i just found out i got a very small leak in dead center of my 480 radiator, so small that it just there is no wet patch, but just hint of blue UV pin size spots when black light is on, so i was wondering could i use a solution like rad-fix to get rid of leak?

not sure about rad fix but when I accidentally screwed damn hoes into my pa120.3 a few years back I used gasket seal, basically the stuff used on engines. Worked a treat.

I broke off the bleed screw in one of my rads, so i drilled it out, cleaned it back to the bare brass with a scouring pad, and then heated up the area and dropped a blob of solder on it. I used a plumbing torch to heat the area, dunno if you have access to one, maybe a lighter would do.

Make sure ya clean the rad out thoroughly after if ya do this, dont want bits of solder rattling around ya system

well this was not result of me screwing in screws too far as leak is opppisit side of fans which is in pull cofig rad sitting on side 480 rad, probbly why it took so long to find out,
dazzerd only thing im slighty worried about is i got koolance non drip quick disconnects to the rad, so if i use the sealent of any discription would this foul up my quick disconnects in (forming a unremovebil seal as this stuff you mentned is a permint fix)
any one here who has had exsperance using this stuff i would like some feed back if possible ,thanks.

hhm not fully sure I understand what you mean.

Gasket seal is a permanent fix yes (though you can actually burn or drill the stuff out should you wish) but I don't see how this would effect your qdcs. Gasket seal is not very runny, in fact the stuff I used (I used this http://www.halfords.com/webapp/wcs/..._productId_173106_langId_-1_categoryId_255217) had the consistency of tar. All you would need would be a tiny drop on the hole area. The gasket seal won't leak through the hole unless you force it through. No idea how it works but it just bonds itself to the metal and you will be left with what I can only describe as a shiny rubber seal.

You will want to pressure test externally before you put it back in your system. But this stuff is designed to stand higher pressure than what any normal pump can produce.

Some jb weld will do the job, worked a charm on my thermochill rad.

Solution? lol, don't add anything to your water to fix a leak, either repair externally or just replace the radiator.
