This is for a 07 V6 Accord, I thought I might get more answers here. The new belt seems to be moving left and right just a tiny bit, perhaps it just looks that way. I tried pushing the auto tensioner forward with a serpentine belt tool then adjusting the belt but the belt seems to scoot itself back to its "normal" position on the pulley if you call it that. Belt isn't slipping or anything. Just wondering if this is normal. I have the service manual and there is no mentioning of 'alignment' of any kind other than routing the belt back properly and release back the auto tensioner.

Auto tensioner and belt are from Gates.

thanks

if its not causing any problems i'd leave it alone. theres really no way to adjust it that I know of

One (or more) of the pulleys may be out-of-alignment, from either wear (worn bearing) or damage to the bracket. There are special lazer tools to check pulley alignment, but a simple straight-edge (I use a steel ruller) will work.

For complete diagnosis of belts and pulleys. The first part is specific to RDX belt replacement, but just scroll down to later posts, for diagnosis procedures:

The belt seems be going left and right on the auto tensioner pulley. And the pulley before that is the crank pulley. I think I didn't notice this before because my old belt was stretched and the auto tensioner was also bad. Not to mention Honda left out the auto tensioner alignment bolt, the small one at the lower left hand corner. I drove like that for 80000 miles, I'm surprised nothing serious happened. I only found this out because I replaced the auto tensioner myself. I do have a slight left and right movement on the crank pulley, Honda last worked on my car When they changed the timing belt at 98000 miles, I'm now at 170000 miles. I'm not sure how to correct this other than taking the crank pulley off and re-torque it down. The power steering pump pulley, alternator pulley, and A/C compressor pulley all look good.

The car drives fine by the way and I've tested high rev to 5000 rpm at idle
