DF,
Hopefully you got your car issues sorted out on the tensioner/alt pulley deal. This weekend while driving(my wifes gasser as mine is under the 01m-5 speed knife) I was thinking about our issue with the fans kicking on too early for our "Hybrid" T-stats. I was able to look at the Bentley, and it seems that we can cut one wire on the radiator thermal switch and install a toggle switch which will disable the Stage 1 fans from coming on. This will render the Stage 2 fans operable, and also the fans would be operable when required by the AC but the low temp slow fan kick on would be disabled. If I wanted to go back to normal I could just flick the switch back one, and all would be back to stock.
Stage 1
Switch on .......................197-206 deg F(92-97 DegC)
Switch off........................183-195 deg F(84-91 Deg C)
Stage 2
Switch on ........................210-221 Deg F(99-105 Deg C)
Switch off.........................195-208 Deg F(91-98 Deg C)
In the latest days testing the "Hybrid" T-stat I did notice the fans kicking on, so I know that is sapping some MPG's from my numbers. Looks like this will be an easy way to make our fans not kick on until it reaches 210 Deg F.
