07 Volvo VT830 D16 coolant temp issue

My coolant temp normal stay just the 170 mark on the dash when outside temp is around 75 and below, even going up a hill with a slight raise. As soon as the outside temp goes above 75, the coolant temp starts climbing up to the 210 mark if I don't turn on the fan.

I changed the CAC and radiator because they was leaking, thermostat, and egr cooler. Don't know what else that would control the temp of the coolant.

Any advice would be appreciated

It stay shy of 210 on flat roads, at speeds of 65 to 70 mph, Won't hit the 210 mark so the fans will turn on. I have to manually turn on the fans to cool it down. If not it stays there. Just wondering why it does this s soon as the outside temp good higher than 75 to 78 degrees.

 

Not my, I have to manually turn on the fans. This started a couple of months ago, just dealt with it since it was winter, now it's starting to get warmer. Have to get it fixed. I also changed the dohicky thingy that controls the air to the fan clutch.

 

The fan only comes on at 210 when rolling. when idling like every 15 or so with ac on. Last summer it stayed hovering above the 170, then I think it started when I cleaned the EGR air tube sensors. So maybe I just answer my question.
