Any upside-down "U" shape in the hose disqualifies that hose as a path for your heated water, because an air bubble will likely exist at the top of the U. Just FYI.

I have it way too easy. Toyota has a machined port in the rear of the engine block for the heater. All I have to do is remove the airbox, move the clutch bracket, coat the heater with thermal grease, shove the heater into the port until it clicks, reinstall the removed parts and route the AC cord. I'm estimating under an hour or less and the cooling system never needs to be opened.
