Maybe I need to be more forceful in explaining why you should not try to use PVC plumbing.

The water system will not flow if there are any air pockets in the system.
The water system will not flow if the thermostat does not see the hot water
returning from heater circuit so both heater valves must remain open or
install a bypass in the ?" line.

The thermostat never opens like most cars.? It only opens a little when it
needs a sip of cold water from the radiator which remains cool.

The Subaru thermostat keeps the engine so warm that the overheat light stays
on in some vans.? A low water level also will make the overheat light come
on .
