I assume, that when buying a rad, that they still need cleaning as soon as you get them? I'm getting a black ice sr-1. The first thing I do is I'll flush the rad out, with boiling water. I've read that modern rads don't really need to be flushed with vinegar anymore?

In which case, I'll do the following:

Fill the rad full with boiling water.
Empty half of it out.
Shake for a few mins.
Empty the rest out, checking the state of the water.
Repeat until water is clean looking, and do a final flush with distilled water.

I don't need to clean out the other components right? As that'll be done when I prime the loop?

Thanks :)
 
Wait for the water to cool a few minutes before filling the rad, let it sit for a bit then drain some off and plug the rad inlets. Wrap the filled rad in a towel or use gloves, it's going to be hot and do the shake and bake dance for a few minutes. Empty rad into a bowl and inspect the water, there will be little bits of aqua/blue/grey. Repeat until the water is clear. Rinse your blocks and fittings as well just to be sure, no need to heat the water for those though :)
