Loving both yours and Erics builds. Paving the way for probably the most custom modified tfsi setups ive seen.
I bought some of Erics old rad hardpipe setup and I'm looking at running a coolant overflow similar to yours. I can't quite figure out were to run the bleed line from and the feed line to? I'm assuming one goes from a port on the upper rad hose?
The bleed line goes form the highest part of that upper pipe, and the feed goes down in to the thermostat housing. I cut the pipes to the thermostat housing and welded on an AN fitting to run a -12 AN hose from the tank to the thermostat housing.
Torqued and marked everything to do with the subframe except the control arm bolts up front (wrong bolts are in there currently). I'm also holding off on installing the aluminum control arms and spindles until everything else is done.
