Is a brand new rad supposed to look like this?

[Artem]

Sorry guys, first time watercooling and I have a lot of questions. When looking inside my brand new alphacool ut60 360 rad, the copper inside seems to have corroded... Should this corrosion go away if I flush it with water and vinegar? Seems a little excessive for a new rad...

Flush it out

Flush it out

Flushing. For how long?

that isnt flushing man 

 

the color you are seeing is the heat discolorationg of the copper, its from when they soldered the fins on, dont worry about it

This is after filling it with water, shaking, emptying, and repeating. I left it running with a water and vinegar solution to try and get as much oxidation out as possible. Green growth on the actual copper is not from soldering, it's oxidation. Kinda like when pennies turn green.

It's nothing to worry about, as many have pointed out, flushing, vigorous shaking will help.

I heard you're not supposed to use vinegar to flush because it causes corrosion. Is that not true?

A weak acidic solution is usually used. You shouldn't use it with nickel plated things but it's fine with copper.

Oh I knew it was bad for something. Thanks for clearing that up!

This is quite normal that a radiator looks like that from the inside. And you did the right procedure here already by flushing it. I did never take such close up pics from the inside of my radiators lol.
