Re: cooling fan
Yes the thermostat opens at 185 F, Cooling fans kick in at 221 F and the warning light comes on at 239 F.
Now on the 99-2004 the fans kick in just before the red, on the 05 they kick in around 5/8 to 3/4 full scale on the LCD. If you want to test your fans disconnect the cylinder head sensor, the fans should run with it undone. Sensor is at the back of the head (#3) and the connector (2 pin, #4) is behind the battery cover tupperware.
