Default 3-chain IMS procedure: Tensioners

2003 base. I have the crank and all 4 cams locked. Do I need to remove all three chain tensioners? Is there one under the AC compressor?

Do you mind sharing your procedure?

I basically did the L&N procedure with homemade tools. Didn’t take out the tensioner under the AC. I just realized it would pull the other side chain tighter with very little force (short moment on the supported side of the IMS), that it wouldn’t be that much of a problem. When I did it the unsupported end of the IMS was maybe 1mm off center and I could easily center it by hand.
double checked the timing when I was done and I’ve put 100 miles on it since.
Of course at 70k miles the bearing that came out seems fine but I can stop worrying.
Thanks again to JFP for his presence and support on this and other forums.
