I'm assuming it's not under warranty?

Any kinks in the hoses? When you replaced the thermostat, was ALL the air bled out of the system?

My cooling fan went bad after 24,000 miles. I was glad it went bad before warranty expired it was a 700.00 repair

If the fan is not coming on, then it is probably the fan itself or a relay or something like that. I believe the fan will come on at 216F if it is working properly. Mine will get that hot if idling but of course the fan then turns on and cools it off.
