It would help a lot if we had any idea
1) what model and year you are driving
2) what engine it has
3) rough idea of the ambient temperature
4) Knowing the mileage is often helpful too.

But not knowing any of that I would check the clutch on your
mechanical fan (if you have one). Basically get the engine warm and
shut it off. When hot the clutch should bring the fan to a halt
immediately. If not the clutch is shot and your idle temps will go up
fast.

I would also check inside the radiator for coolant flow if the flow is
not good you may need to flush things out or possibly replace the
water pump (I've seen old pumps where the impellers were corroded to
useless nubs even though the exterior looked great).

It could be a bad thermostat.

If you haven't had to replace the water pump with over
100,000 miles, I'd change that on principle along with
the fan belt.

Just an update........

Needed to replace
Radiator - blockage and small leak
Thermostat - bad

Thanks for the suggestions
