I managed to remove the OEM damper by just loosening the bottom two nuts holding the fan shroud and collapse the schroud forward. I wiggled the OEM damper out passed the fan (barely). While I was at it, I did the “tone ring” mod as well. Now the Fluidampr is about ½” thicker. When it was time to re-install the Fluidampr, NO GO because the fan is in the way. Is it necessary to remove the fan? If so, how do you go about doing it? I can see two sets of bols, one is 6 13mm bolts attached to the fan facing the front and 6 more smaller ones facing the engine. Which one do I remove to move the fan out of the way about ½”. I even tried to re-install the OEM damper it too did not want to go back to its old home. I appreciate any help. Thanks.
