Update: Put in new t stat and water temp sender plus new expansion tank cap. Now flushing system and putting in new coolant. I really now am a believer in Murphy's Law. Why do straightforward jobs turn out to be nightmares? First, could not loosen bolt that holds dipstick tube to engine. Had to pound allen wrench into hole in bolt and then pound wrench with hammer and it finally broke loose. This took about 1 hour. Could not get to back bolt on t stat housing so had to take out dipstick tube. It would not budge but finally after about another hour finally came out. Put in new t stat and then had to re insert dipstick tube. Again, after a couple of hours I had to take off dist. cap on passenger side, push up plug wires and insert tube behind wires to line up with hole going to oil pan, then get wires in front of tube. Tube would not go all the way down until I kept pushing and twisting for about another hour and finally got it down to where I could re attach it to bracket and bolt back to engine.

Appears that while I am flushing and let engine idle the temp is ok but won't know for sure until I take it out on a drive.

Another simple job that took about 5-6 hours in a 90 degree garage with sweat running in my eyes. Why do I do these things? Oh yeah, getting the hose elbow back onto the t stat hosuing was a real pleasure also..about another 1/2 hour.
