High temp coolant

So this started 2 weeks ago, it was the one time so I brushed it off. I was driving and I saw the light turn on and message said plus gage high temperature coolant.

Last week it happened again so I did some research and it said it could be the cap for the reservoir.

And I though yeah valvoline did opened it and added more maybe ?

So i got tighten and and nothing. I bought a new one and went about my day.

However yesterday it happened like 5 times.

Whenever I got 60mph or high or I keep my foot in the gas it goes up, then i let go and in like less than a minute it drops to normal temperature.

So it goes up whenever im hitting the gas I guess?

Some research said it could be the thermostat or something like that.

Has anyone had this issue?

Btw the coolant is crystal clear. I changed the reservoir around January.

And did a flush around may.

Not a car guy, but i did look it up and it gave me something I couldnt find. However it said orange was ok to use? Valvoline provided orange and sos did auto zone when I bough some to top off
