How to remove ac compressor 1999 Cadillac Deville

(1999 Cadillac DeVille)
It's a very tight space; I know it comes out thru the passenger side wheel well. I know it helps to remove oil filter, but what about the oil filter housing held on by two 10mm bolts? That one 13mm bolt on the back of the compressor is tough to get to.

1) Take off the serpentine belt,disconnect the negative battery terminal & loosen the lug nuts on the front

passenger side wheel.

2) Raise the passenger side of the car and place a jack stand right on the front corner of the frame.

3) Remove the the front splash guard then the oil filter and while the oil drips out remove the tire you

loosened & then take off the two splash guards behind it.

4) After the oil stops dripping remove the bolts holding the oil filter adapter to the engine. One bolt is

accesible through the oil filter hole the other you need to use a socket with an extension coming in through

the space where the front splash guard was removed. Once thats done move the adapter out of the way.

5) At this point you will have clear access to the bolt holding the tubes on the back of the compressor as well

as the bolt that holds the rear bracket to the engine. Remove the bolt holding the tubes first (15mm I believe)

and then the bolt holding the bracket (10mm)

6) Next, in the wheel well loosen the left side nut but dont remove yet. Remove the right side bolt & then the

top bolt. You will need to use one hand to keep the compressor from leaning while removing these two bolts.

After that remove the nut you loosened first. All three are 15mm.

7) Pull the compressor towards you until you can see the electrical plug. Unplug it and then remove the

compressor. Once out remove the rear bracket from the compressor.

Total time about 1 hour, an hour and a half tops.
