Serp Belt -Tensioner & Pulleys
N54 here -- had to remove the fan assy -- turned out that the drivers side rubber mount boot / clip was the hardest part of the job. Took me an hour to just get the fan out. Once out -- everything was accessible even with the
darn air duct running across the front (bolts out and generally out of the way). I also had to remove the IC charge pipe (some oil traces even with my BMS OCC) At 85k -- the belt and pulleys looked in great shape & bearings on all were smooth rolling and no noticeable differences from the new INA parts. Ordered from one of my favorite vendors ~ ECS Tuning . Conitech Belt & INA Tensioner & Pulleys . For sure an easy DIY with a big savings over dealership pricing. |

I just did the same thing yesterday. I'm at 61k. I changed the belt, idler pulleys and tensioner along with coolant and P/S fluid.
I also found it pain to try lift the fan out and try to get that charge pipe off of the rubber mount that's attached to the fan. Since I also change my coolant and P/S fluid, I actually had the intercooler off so that made it a little easier. the intercooler was much easier to remove and reinstall than I thought it would be. I also had a little oil i my charge pipe. I don't have a OCC though so I feel better that a little oil in the charge pipe is "normal" in these engines.

I have to change my belt soon also. How can you determine whether or not a the tensioner, or any pulley needs to be replaced as well? Do some folks just do it proactively?

YES
If it is a difficult journey -- better change everything out while you are there -- you don't want to make a repeat trip anytime soon. They are know to fail prior to 100k.
