Buggy radiator plumbing set up
Can anybody summarize there buggy radiator set up? Pics? I plan on running aluminum tube closed system. Heater line (Subaru) plugged. Wanted to use
a surge tank as a filler. Was told run one line to highest point in radiator plumbing. One line to highest point in engine ( water manifold). One line
to an over flow tank (necessary?). Where would the other line go? Pics would be awesome. Thanks.

How have the heater lines been plugged? is a big job to reconnect?
Keeping the system as close to stock subaru as possible (standard thermostat/waterpump setup, heaterloop and bypass in place etc etc) and a well laid
out fill point/header tank is the best way to go.
Alot of people don't follow this and end up with a cooling system that is a pig to fill and bleed, gets air locks or runs hot.

like Joel said . go look under the hood of a subaru and just plum up the hose like the subaru , and you loop your heater hose so that the
water/coolant flows around.

The heater loop return is part of the thermostat. You must loop the heater if you do not use it. The return hot water is what opens the thermostat.

Isn't it the same as plugging it? Just means that the water has less travel before it can do its job.

No it's the complete opposite.
Subaru and most Jap cars have the thermostat on the cold side of the engine instead of hot.
The heater loop is critical so the thermostat can see what temp is the engine is running at by the coolant returning from the heater.
All cooling systems have some sort of bypass system for when the thermostat is closed.
A few of the Japanese manufactureres like Subaru and Mazda have worked out by having the 'stat on the cold side leads to quicker warm up and more
stable temps.
