My 04 TB 4X4 has started running between 210 and 230 lately, i've already replaced the thermostat and fan clutch and I seem to be getting flow from the water pump, my last idea is to reset the computer, but how do I do it???

I believe all you have to do is disconnect the battery and reconnect. Not sure how long you are supposed to wait though. The computer will relearn the truck.

if you are going to pull the battery make sure all your fans , radios are shutoff before doing it ... Myself I would find the pcm fuse in the fuse box and pull that instead..
