Replaced thermostat, coolant sensor, radiator fan and fan harness and fan relay, doesn't seem as if thermostat is opening as it should. Thought day old thermostat was bad but 2nd new one doing the same thing
No coolant loss, thermostat doesn't open all the time upper hose hard as a rock when it doesn't open.

How badly did it overheat and how many times?

You should check to see if the head gasket is leaking. Get a block test kit

Is the replacement thermostat OEM? I believe you should be looking at it one more time.

Quality of thermostat matters.

Even new thermastats can be bad right out of the box. Would get a OEM like KILlow says. It may also cause the temp sending unit to mess up. Check any wires. After replacing the thermastat check the guage if it still does it the sending unit could be going bad.
