hi, english is not my first language so i cant understand how do you removed the cap, what kind of solder to desolder and how are you goin to put the cap again thank you very much. i think i have a clogged radiator so i want to give it a try
@idusclothing not sure where you would buy a replacement core in your part of the world, my guess would be to shop online and mail order it.
if the core is not corroded through you can flush it with water and carefully 'rod' out each tube with a thin metal strip (being carefull not to damage the copper tubes)
an thin flat engine dipstick works well for this if its long enough
Great job Aussie!... usually I use propane and oxygen with a little "rexarc" torch and an air nozzle instead of welding rod to removal the radiator tanks
either one works well when done right. my mapp torch head is a bit stuffed and makes a very large flame, but as you said, oxy acet could easily melt the brass or copper

so with the core being copper brass rad, does that mean its a cheap replacement?
Is it the tanks that are of value?

@idusclothing nah its a factory rad, all the cheapies are plastic tanks with alloy cores
the tanks are worth keeping because new copper/brass cores can still be purchased

@Aussie50 Where do you find Cores without tanks?
I ask because I have a 6.2 Chevy diesel im trying to cool, so I went to my local junk
yard and found an old ford maverick rad. It has 3 cores and it is brass/copper core.
Core looks clogged, but the tanks are in great shape.

pretty easy to do especially with a blow torch i think oxy acetylene may be too hot and may easily melt copper

MAPP seems to be working well for this job.

yeah, it requires very good torch control fir oxy/acet. very easy to burn the brass

i never thought about scrapeing the solder off... seem alot less destructive than banging and a hell of alot cheaper than using solder wick.
Awesome!
