The Tip S cars do run a little cooler (maybe 3°-5°F) because of their added air/coolant transmission cooler.

This is basically a 3rd (or 4th for the 'S') little radiator on the same circuit as the engine coolant.

The Tranny does add some heat, but the transmission cooler (in conjunction with the main radiators) more than compensates causing the coolant to flow just a little cooler.

FYI, those with '00 MY or earlier cars can access a digital readout of the actual coolant temp (as opposed to a somewhat inaccurate needle arcing across a mostly non-graduated gauge face) by putting the Climate Control Unit into diagnostic mode and reading the value for code 6c.
