Ok, I have next to no heat in my bus. I've never had this issue before. My
mind says it could be a stuck or dead thermostat. However, it has also been
like -6 to -12 her all week so I have also considered it could just be too
damn cold out :)

Coolant levels are good - although the last few months I have has to add a
bit about every two weeks or so (I see no leaks at all and do not see any
signs of coolant in the oil).

So I thought I'd replace the thermostat with a new one jusat to be sure.
I've heard that can be a PITA. Any thoughts, tips, etc on my lack of heat
and replacing the thermostat?
