Uh oh, Vinegar???? Did you wash it out really really really really good with really really really hot water??? (I'm being a little sarcastic here, but still serious.. )

If not, make sure you do that, and you'll also want to clean out your pump and res now that it's got that vinegar in it too.
We don't recommend usuing vinegar to clean radiators anymore, it's better to use just hot water, you'll avoid many problems doing this.

Looks good so far though!! MORE PICS MORE PICS!!!!!!
