These engines are a bit difficult to get the cooling properly "burped" if you have had a lot too little for some reason.
When I did my coolant change I thought I was finished at one point but managed to get one full quart more in there when following som Youtube tips.

I’ve put it on an incline. Heat on high ran for 20 min 2k-3k rpm and it took awhile but it got up to the bar under the red temp wise. Still no heat and coolant still full. And upper radiator hose did get hot
