We had hard time getting air out and enough coolant in so as not run hot. i am still hearing water sloushing behind dash. what do i need to do now? also how do you install actuator door, not getting air or heat from center dash vents.

Noise has to be coming through heater core. Sounds like problem with it unless you have an air pocket somewhere and need to find out how to bleed it. I'd suggest getting a radiator cap with pressure release if one available for your model that may help.
