Embarrassing question:  Where on an 85 1.9L motor with a manual transmission is the Temp Sensor 2?  (got it on my list to clean the contacts and maybe even replace since it's 25 years and 194,000 miles old)  What does it look like?  What color wires, and how many, are leading to it?  If you remove it does coolant flow out?

Absolutely.

Sometimes it's the connector to Temp Sensor 2, sometimes it's the sensor itself.  My '85 has done both.

Clean the connector really well with contact cleaner, then with something gentle to medium abrasive, then flush well with contact cleaner to flush out any abrasive left.  Wait for the cleaner to evaporate.  Help it along if you want to.  Be careful if it's flammable cleaner.

If that fixes it, great.  If not I'd try a new sensor.  They're not free but aren't bad pricewise.

And I have an O2 sensor issue, I think.  But I'll leave that open until after New Year's Day as I won't have time to address it before then.
