I looked at your home base before commenting and guessed it was a little warm on the cruz outside. Easy to prove if hcollado has it nailed for you. When it starts to hit 200 degrees bring RPM's up to your cruz RPM ( I guess about 2K ) and see if temp comes back down to the T-stat or 180. If it does not come down with just RPM then air flow is issue not coolant flow. Just hope you get a handle on it so you can get back to cruzzin ! Don't over look the
oil temp as a source to shed or add tons of heat to system.
