In summer city traffic and especially when stopped at a light the a/c is running, the temperature gauge shows running at high temps. Usually doesn't go to red, but has a time or two. Also, sometimes oil pressure light will begin blinking. Doesn't seem to happen in cooler weather. Recently had radiator cleaned and small hole repaired. Not loosing coolant as levels remain fine. Also, I checked to make sure both radiator fans were working and they seem to be fine. Is this likely a thermostat issue or something else?

Replace the thermostat and bleed the cooling system and see what happens
