Hello, my name is***** you for the question. When you get these two symptoms together it is typically because the coolant level is low or the thermostat is not opening. I would check the coolant level first. If it is low then add some but the vehicle will need to be inspected for a leak. If it is full then it probably needs a thermostat. I hope this helps. Let me know if you need further assistance.
