Excerpt from "Repowering the Vanagon" brochure from KEP RADIATOR PLUMBING. Copper tubing is the easiest way to plumb the radiator. Copper is not compatible with the aluminum engine so it is important to keep a good corrosion inhibitor or antifreeze in the system. The ‘86+ Vanagon used special plastic plumbing which works works fine. Do not attempt to use PVC plastic tubing because it will not withstand the required heat and pressure. Customer wrote:

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 . Susan Kennedy Engineered Products
