New Water Pumps

It was a long and arduous task but the new water pumps are finally installed and the Merc is back on the road as of about an hour ago. I need to polarize the gen as it is not charging. Temperature stays down on normal and no more coolant leakage now. Except for the hose connections on the bottom rad outlets that needed a little tightening.
What now? Brakes maybe? New gas tank?
