My 2008 Freelander had a heat vent in the bathroom. Allowed us to get it nice and warm for taking a shower. My mistake for assuming FR would do the same on the upscale and more expensive 2016. Looking for furnace vents wasn't on my list of things I thought FR would ignore.
As they say shame on me for assuming FR wanted a return customer on this discretionary purchase. When they scrimp on the big stuff like heat to a bathroom then you can just imagine all the corners they cut for stuff you can't see.
I am going to look at installing a fan in the wall between bathroom and living area and wire it to furnace power circuit.
RE water pump fitting. There is a special slip fit fitting that is retained with a blue plastic "U" clip in the inlet side of the water pump.
The FR instructions say to pull the clip then pull the hose fitting out of the pump. Then insert the new slip fitting that has a long hose that you stick into a jug of antifreeze to suck the antifreeze into the system. Of course to do the above you need to empty most of the basement so you can remove the 6' wall panel to see the pump before you can then try and connect into the system,
Here you can see just how much work room FR provided. The blue box like thing on the side of the pump is the clip but you can also see that there is no clearance for hose to be removed. In the picture I am holding a screwdriver and trying to loosen the screws that hold the pump down. Can't get enough torque with my fingertips so it is essentially impossible to winterize my coach per FR instructions. When I asked FR and my dealer I was essentially blown off.
My 2008 had a nice water control panel that made winterizing a snap. Connect hose from jug of antifreeze and turn a couple valves, turn on the pump and you flush the system with AF.
