Seller wants another week to see if his insurance will cover the sewer repair, works for me I got some cycles for my truck.
One of the least cherished pieces of advice I give others is "one of the things you believe to be true, may not be true." I thought I had the coolant system bled because I did everything I did on the Camaro, and that thing will melt your socks off. Plus the truck doesn't overheat at all, totally normal temps. Regardless, I felt like I had some heat the first time I filled it up, and zero now, so a regression in functionality may imply operator error.
I unfolded the strange marked paper that came with the funnel. Turns out there's instructions and a labeled diagram of the components on there, which was enough information for me to choose the correct combination of adapters to get the funnel to not leak when filled this time. A critical improvement. I was mentally prepared to get the duct tape out. And I mean the Class 1 Duct stuff they use in the trades, I was serious. Fortunately it didn't come to that. I poured a bit in and fired it up:

The coolant expanded as it warmed up:

Once it got to thermostat open temp, I started snapping the throttle, holding revs at 2k, squeezing the tubes vigorously. I got bubbles, success! I kept going for a while, seems like revving it closes the thermostat with the temp drops so I'd give it a few minutes to heat up, then crack the throttle and I'd get a few bubbles. I figured it was the perfect time for an exhaust video, so here's what I ended up with:

The extremely boring pause in the middle of the video is me watching a huge release of bubbles, sorry you're kinda along for the ride here. I guess my tune needs some work but I don't normally crack the throttle wide open like that.
Anyway, after 45 minutes or so of really givin 'er, I was rewarded with somewhat functional heat! By the time I shut it off, the cabin was actually pleasantly warm. The heat is far from great but it's definitely happening which is a huge improvement. Defrost is critical around here this time of year.
