Good find for those pictures. I don't know if there is sealant on them from the factory, but I would put some on. I like liquid Teflon type products rather than Teflon tape.

I looked at the liquid Teflon that I use on residential plumbing and its temperature range is 0-350 F and 200 PSI.
Not as cold as it can get here with this winters low on the order of -20 F.
Google puts the operating temperature range of a combustion engine in the low 200s, so that looks to work.
Might I suppose that the low temp will not matter if the system is not under pressure?
I got this from home Depot and may have used it on some car stuff as well, I don't remember. It's listed liw temperature range is for storage and application not service. At any rate, my stuff almost never gets below freezing. https://www.homedepot.com/p/RectorSe...1630/203490732
removing V8 engine block coolant plugs - too much?
I can be overzealous, and find there are less extreme ways to get the same result.
Would I be as well off running a radiator flush prior to replacing the coolant, as I would be draining the engine block?
Or would over zealous be doing both?
I'm not a huge fan of flushing because it's difficult to get everything out. Even if you run a hose through it, you then have hose water to remove and replace with distilled water. I think many problems come from hose water more than anything else. Might be able to help a badly rusted block...but why did the block rust inside in the first place?
If you flush, do a couple of drain and refill cycles with distilled water. Removing the block drain plugs does help and most people don't go that far.
After crawling under the van I do not see the passenger side drain plug.
It would be behind the starter (?). There is a hole that might allow access,
but I do not want to dump coolant onto the starter or remove the starter just to do a coolant change?
No. I see gallons and gallons of distilled water in my future.
I have not purchased from RockAuto before and am very dubious of a business without any customer support.
I found the lack of CS when looking for assistance to identify a part.
Maybe I just did not want to make a video game of it, but is there a "returns policy" ?
Rockauto has a great return policy. But they do make you pay for the return shipping. I recently returned over $200 in parts I didn't need, and had to take $9 for return shipping out of my refund when they printed the label for me. But it a pretty much hassle free process.
If you have an issue with a part, they will ship out a replacement free of charge though, based on my past experience. And they payt the shipping on the return of defective parts. For some reason, I bought a batch of 4 wheel speed sensors for a 2012 Subaru, and 3 of the 4 were defective when I went to have them installed, and they took them back and paid for the shipping.
