Probably needs the fan clutch solenoid that delivers the air to the clutch to release it. Its probably mounted on the firewall just follow the airline from the clutch and you should be able to find it.

what he said, check the lines for leaks also.

Those temps sound about right. When you get the fan problem fixed it'll routinely go up to 217 before the fan kicks on if you let it. You probably see crazy high egts too. The only way to fix any of that is to unbridge. The cheapest fix would be to get a 6NZ flash from Haney, upgrade the turbo then you'll have normal temps, better power, economy..

Probably late but if the fan is running all the time sometimes the a.c. high temp switch is faulty. If you can find the switch, unplug it a use a jumper wire to cross the terminals. If the fan shuts off its very likely the switch or the a.c is not charged.
