It might not hurt to have your cooling system flushed and see if that along with bleeding the air out of the cooling system helps.
A new thermostat would be worth trying too, if it hasnt been replaced in the last couple years.
If you have the proper antifreeze mix you shouldn't be boiling at all.
Here are how the fans are set...
Quote:
The PCM commands Low Speed Fans ON under the following conditions:
The engine coolant temperature exceeds approximately 106°C (223°F).
The A/C refrigerant pressure exceeds 1310 kPa (190 psi).
The vehicle is shut off when the engine coolant temperature is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay ON for approximately 3 minutes.
The PCM commands High Speed Fans on under the following conditions:
The engine coolant temperature reaches 110°C (230°F).
The A/C refrigerant pressure exceeds 1655 kPa (240 psi).
When certain DTCs set.
