Fill the loop with fluid, likely pure antifreeze, and allow the heat differential in the fluid to move it around.
My question is, how hot does that pipe normally get? I certainly don't want to boil my WVO in my tank. Especially since I'm just using the plastic cubies that the oil comes in new.

I'd guess that at highway speeds, the exhaust temp is in excess of 450°F.
However, unless you seal that coolant loop, the coolant temperature will never exceed the boiling point of the liquid in the loop. If it is sealed/pressurized (and I don't recommend doing that) the boiling boint of the coolant will rise 3° F for every 1 psi increase in system pressure. Obviously, there will be some additional heating because of conduction from the metal in the exhaust to the tubing on the heat exchanger too.
