( i premixed it). i ran the bleed process to get the old coolant and new to mix since i didnt want to run the pump while there was minmal amount of coolant in the system. after the bleeding process was done i drained and repeated the process 1 more time. it seems like i was able to get most of the old coolant out and replaced it with the new one.
I did use extra coolant but i didnt want to get to that hose which seemed tight to get to.
anyway thanks for the help. and advice again

I don't think you'd run the pump dry if you ran the bleed to drain additional coolant. You'll never get all the old coolant out so there should be some to keep the pump lubricated. But better safe then sorry.
