Where is the coolant temperature sensor located?

Hi,

There are two engine options, a 3.1L and a 3.4L. If you look at picture 1 below, that is the location for the 3.1L. It's right next to the thermostat housing.

On the 3.4L (pics 2 and 3), there are two. One functions for the gauge and the other is used by the PCM for other operations such as air/fuel mixture, cold start, and so on.

I highlighted the engine size in both, and the sensor identifiers are highlighted for the 3.4L.

Let me know if this helps.

Take care,

Joe
