my intitial gut-guess-design-thought, was to include an expansion tank
as the system would end up under pressure. (are the VW expansion tank
caps vented???) I'm sure that in a closed circuit, the coolant would
not boil off quickly, though when not in use (pump off) maybe coolant
at pipe around exhaust would. ?? No biggie. It's not like it would
harm anything.
My take on this is that this system would be similar to the cooling
system on a wasser engine.
And yes I agree. Insulating boxes would help. Though not sure what
material *wouldn't* be subject to ingniting. I'm pretty sure pipes
would get hot enough.
