Hi,

The vehicle will have one sensor. However, there are two variations for location. One is on the side of the engine and the other is on the front behind the crankshaft position sensor.

You will need to check your vehicle to see which one you have.

To get you started, here is a link that shows in general how one is replaced:

Next, if you look at the attachments below, I've included the directions and pictures for both.

Let me know if this helps or if you have other questions.

Take care,

Joe

Hi,

The impact wrench should have taken it off for you. What kind of impact are you using? Is it battery-operated, electric, or pneumatic?

I attached the directions below specific to removal. It is a straightforward procedure.

Which bolts bent? You mentioned there are two.

Let me know.

The bolts that bent where the ones that are put in to keep the pully from spinning. And it was a pneumatic wrench you know and air tool. That was after the impact wrench didn't work we tried breaker bars 6 point sockets and the bolts to keep the pully from moving.

The only other thing I can suggest is to put a good wrench on it and smack the wrench a few times with a heavy hammer. That will often break them loose.
