Don't be too surprised if you need to add 1/2 - 3/4 gallon of antifreeze after the fact too. Depending on your dealership/technician, they may not top off the overfill tank. From what I understand, FCA expects the tech.'s to re-use the coolant that spills out when the old pump is removed.
My dealer replaced my water pump on 3/19. When I picked it up I asked the service adviser if the coolant was only drained enough for replacement or complete drain and refill. He told me they always do a complete drain, including warming up to let the Thermostat open so that all coolant drains out, then a complete refill of fresh MOPAR grape juice. Also, the overflow tank is full right up to the correct line.

That's great that your Dealer is doing that. But my question is; how much coolant is lost when you take the pump off? It looks like the pump is just an impeller with a pulley and very little fluid would come out when you take the pump out. On the other hand, you might lose significant fluid with gravity pushing it out from the radiator fluid level above.
Just curious.
If you just pull the pump off all the fluid to the level of the bottom of the pump boss/opening on the block will be lost, including fluid in the rad down to that level. So most of it!
