......to follow up, replacing the sensor was quite easy and it
solved the problem. I found why the serpentine belt had
to be removed - it was for access to the water pump. The
factory service manual forgot to mention that the water
pump had to be removed. I realized that when I read that
it had to be reinstalled after putting in the new sensor.
Congratulations on your successful diagnosis and repair.
And thanks for taking the time to give the feedback.
