Engine temperature question

Hello all…. I have a concern about my engine temperatures fluctuating a lot more than usual.

Today I was doing my usual commute and had Hybrid Assistant app running. Noticed my engine temperature fluctuating more than normal. Usually it stays at 195°F and will go up or down if there’s any strain (ie uphill or passing) or coasting.
However, even with the slightest bit of extra use of the gas pedal, it would go to 197-199°F much more quickly, and stay at about 197 longer before going back to 194-195°.

I will admit I may be just paranoid but here’s some background on what’s been done to the car, etc.

Mileage is almost at 147,000 miles. Water pump, thermostat, coolant and spark plugs done at around 100,000 miles. EGR system, intake, etc. and catch can done maybe around 110,000 miles (don’t remember the exact number). No oil is burning, and no observed coolant level changes.

I do have an extra EGR cooler cleaned and ready to go once I tackle that whole thing again, as well as a brand new EGR valve that I plan to install at that time.

Again, I’m probably just reading into it more than I should but just thought I’d get some insights from here.

Thank you!
