Somewhat productive day. Well, I guess it started last night. My son and I drained the coolant from the petcock, disconnected the heater core hoses and vacuumed out everything we could from the heater core, engine, etc. We still only managed to get about 2.5 gallons out. Because of that, we ended up flushing it 6 times total. Once with a flush, 5 times with distilled water. It took awhile, because we'd run it to 208+F for 10-20 min each flush, then let it cool off. After the last flush, the shop vac was full of clear water. No sludge out of any of the flushes, but it's nice to know it's clean, get the maintenance done, and show the kiddo how to do it himself. Not much to picture there. These are the heater core lines I disconnected, then vacuumed through both hoses and attached scrap hose to the engine side and vacuumed that, too:

After the final flush, adding coolant as it's running:

Before reinstalling the intake (after all the coolant spilling was done), my son took over and changed the tensioner and serpentine belt. He looked up the torque specs, set the torque wrench, everything. Yes, he released the tension on the torque wrench after he was done. Anyways, super proud. I did nothing except answer questions:

Also, these arrived. Here's a test fit for a functionality test which it seems to have passed. I had to order some 90* HDMI connectors, an HDMI splitter, a 100W PD charger, and a few passthroughs, but the hopes are to have one single USB-C cable charge and provide HDMI to a Switch, ROG Ally, Laptop, ETC. They have the features of tablets on their own, as well:

More to come on this, of course!
