car problem

Hi all wondering if anyone can help me out here

just this week, my car has been taking longer than usual to warm up
and when its starts warming up the temp gauge shoots to almost high and I
hear like a “whistling” sound while the temp gauge starts to get to H…
then slowly the temp gauge becomes normal but rises up and down, making the same sound.

it does this for about 20 min of driving and it dissapears after that

the car is a 95 auto, 240s LE all stock,
i recently topped off all fluids, and did an oil change wich im not to proud to say but i had this done at crappy tire lol… could they have messed something up ?

Possibly a slow acting thermostat? (is that possible?)

Engine heats up, thermostat doesnt open up in time… starts to overheat. Thermostat opens up finally, coolant finds its way to the rad and car cools down.
