Coolant temperature sensor

It is in the engine valley underneath the intake manifold. Part number 3L7Z6G004BA To change it you have to drain the coolant and remove the upper and lower intake manifolds. Then the sensor is in the cylinder head below the intake port.

Thanks man

You are welcome. FYI, you may be able to see the sensor under there, but the sensor has a long probe on it that will not clear the intake if you try to remove it with the intake in place. Seen more than a few folks try that.
