[V6-12v] Sensor for temp gage

[Todd Young]

1) Yes I know the V6 has two coolant sensors, that is why I asked if anyone knew
which one sent a signal to the temp gage.

2) No, the T-stat is fine, that is why I have volcanic heat, when the T-stat was
bad (last spring), I couldn't heat up the interior during cold weather.
