Just an observation but the thermostat is progressive and the fan does not come on until over 200F UNLESS the A/C is on, then it is on all of the time. If not on with A/C you have a fan problem.
In general I have found the 3.2 to be a pretty cool running engine. If you want to monitor the temp, torque pro and a BT dongle do a great job.
