Need some help I need to flush my coolant and refill, was wondering how to re-fill after flush can't see how pouring into the overfill resevoir will fill up the radiator from the bottom up is there a special procedure for this or does it have to be done at the dealer with a special pump system

 

From what I've heard the dealers gotta do it

 

You can take the upper rad hose off and pour it in that way.
