I need help figuring this out. My car temperature is reading above normal near the 3/4 line but it doesn't overheat.

Did complete flush and it dint even had in a thermostat, anyways a bigger fan 12" ( so I have 2 -12" fans now), new thermostat and it still reading high.
Spoke with the Electrican and he doesn't think it's the sensor cause it would have thrown a error code. He also told me to cold start the car the see if it bubbles in the tank, an nope not that either.
My more pointless reasons???

Drive the car up a hill, then immediately jump out and look for bubbles in the overflow bottle.

is it possible all is normal and its just the gauge/sensor out of whack?
Do the fans go on more than they should?
I note an aftermarket rad -- is the flow through it ok? Has it been partially blocked because it wasn't grounded properly?

You put the theormostat around the correct way yeah ?
In the pic of the old thermostat it's the wrong way around

Kong said it's a failing sensor behind the alternator. I haven't had a chance to troubleshoot/change mine yet (3rd gen B4).
No bubbles in my overflow, temp meedle spikes to 3/4 or hot randomly. Sometimes goes up to hot for a minute when i already turned the engine off. I pull out the key for a second turn to ON then needle is back to normal.
Once at a drive thru i saw the needle rapily go hot, normal, hot a few times. Lol

The solution was actually the gauge in the instrument cluster. When I change it. Everything is working now. Had to buy an entire instrument cluster. Thanks guy. That problem solved
