Sorry my point about HOAT is that it scales. My daughters car had it's fluids typically changed around the 75k mark. I don't do all of her maintenance so can't really remember the exact times just the ones where I know I was doing the work. I have had Mopar's and Fords all of my life and had not seen scaling like this until I had cars with HOAT.

HOAT's not vulnerable to electrolysis like the old green antifreeze is, much safer for the abundance of aluminum that's in our cooling systems.
as for scaling, out of the thousands of gallons of HOAT that i've drained from vehicles over the years the only time ive seen significant deposits were from lack of maint. or from using well water or non distilled water in the mix. you may have simply gotten ahold of falsely labeled water. it happens
how many miles are on JB's water pump, and did he say if he has one of those ridiculous SAF-T thermostats?
You could try this technique? https://www.youtube.com/watch?v=YccsacgUJPI

20 bucks says by the end of winter, it'll happen every time you stop. When this happens, reread this thread with an open mind and see that all the information you need is in here..
Like I said, when mine got bad enough to be freezing at stops, it was still volcano hot at driving speeds.
But it didn't start this way, spent months believing it was my heater core (hence me having a replacement one sitting around) until it started to turn into an rpm related problem.. Probably 3ish months of iffy heat before it got there though.
If you want to know for sure, have it hooked up to a scan tool that can give you a readout of the coolant temperatures. Not a code reader, a scan tool.
Still going with my gut, and as I've stated twice though (the first time being in my very first post), my bet lies in this.. water pump going bad due to faulty design and lack of coolant flow.. lack of coolant flow, due to impeller failure and a repetitively clogging heater core.. Heater core clogging from improperly maintained coolant.. coolant improperly maintained due to extra mileage and degradation, as well as possibly being mixed with water that wasn't distilled. Any other water will contain minerals and impurities not meant to enter your cooling system, or mix with your coolant.
All it would take to start this merry go round, is using tap water instead of distilled water in your coolant.. and then get ready for the sh*tshow lol..
I truly believe it's your water pump.
If you don't want to go through the trouble of the heater core then go for your water pump/thermostat/fluid flush.
As I said, not going to be able to change the design now.. And if nothing is coming out, and you're convinced that it's bypassing the cooling tunes through the top of the heater core, then there's nothing left to be done but change it out.
I have 5 DVOMS, and every one of them (except the crappy Harbor freight one) read consistently and surprisingly enough my craftsman ones would come out with exactly the same readings that everyone else's snap on one's would read when I was in college.
My buddy actually would ask to use one of my craftsman ones overy his Blue Point DVOM.
You can get a decent yellow/black one from Walmart for 20 bucks.. but watch testing voltage for more than 10 seconds at a time with it because the fuses in it reeaaalllyyy love to blow.
If you were closer I'd say come over and I'll have it done in an hour even with the mech fan. Really really easy once you make room for it.
