My radiator is dead. Long live the radiator.
Turns out, electrolysis is bad. Real bad. Like, outlet on the radiator was cracked half way around, and couldn't hold more than 3 lbs of test pressure. I'm just lucky the failure was discovered in the driveway, and not on the road. The anti-collapse spring in the lower hose absolutely created the ground path to the coolant and aluminum radiator. I ended up pulling a cap, and the pitting is obvious.
After the bad news, I wasn't in the mood to build, so I took the day for other hobbies - cleaned the rifles, assembled my gear for a coming hiking trip, drank some beer. Today, I started with a good sweep and tidying up of the shop. That always gets my mind back where I need it.
Immediate next steps are making the intercooler outlet route around the radiator. The inlet side clears fine, though you can start to see where I'll have to make side fan shrouds to maintain the airflow path now that the rear vertical boxes are gone.
Building a manifold to go around a notch in the tank.
Transferring the cardboard pattern to 1/4" 6061
You get a general idea how this is going to piece together.
Spool gun arrives tomorrow, and I'll get a small tank of Argon.
