Found this video. I don't think he had a nut on the rear, lol. Very informative.
I don't think I'm going to remove/clean the tank. It was suggested, sure, dont think I didnt see.. But.. The heat is blowing noticeably hotter, and I'm still doing the flush process until water runs clear, distilled in, drive, repeat a few or maybe more times before the temperature will drop before 32 and the G-05 will go in (I chose Zerex G-05 concentrated over NAPA Gold pre-mixed.) It's basically like a varnish, sure, but, compare that to the rest of the system. The flush is going well. This is over a couple to a few days, of course. Similar to @JHZR2
I'm still proud of myself for getting it in. My ratchets didn't let me get the nut on super tight, and 10mm wrench I don't know where it went 🤷♂️It is on there very snug and secure now though. Both nuts.
Oh, and one more thing about that tank.. Someone mentioned I have the "older style tank" earlier on, and from what I've seen that *doesn't* seem to be the case? I may have been inclined to re-do the progress of getting screw in nut after finding and putting in anchor point for bolt to remove and replace with a new clean tank OF UPDATED STYLE, but, unless anyone has info about the updated reservoir, what part number it is etc, my research seems to suggest that the updated one IS exactly the one on there now.. not the one with the black top, which may be the old style one.
The head gaskets is fine, thankfully. No abnormal bubbling as seen by bringing the coolant level up and letting it run with cap off. That is yesterday's color, old stuff coming out.
Now, about the other Pet Peeve on the Ford. Fixed yesterday. Once I became aware the fuses were under dash and not under hood.. was very easy from there.
