This weekend I installed Noico sound deadening panels throughout the van, and the beginnings of insulation in the headliner area.
Removing the headliner on the NV is really pretty simple, Nissan broke it down into multiple panels, which makes maneuvering everything much easier.
You start by removing the overhead shelf, which necessitates removing the sun visors too. There’s 5 bolts up top in the back, and another two under the visors. The visor clips are removed by turning them 90* and pulling them out, and the sun visors are removed with 3 Torx head screws each.
After that, you just pull the shelf straight back, and it pops out. There’s two wire harnesses attached to the overhead map lights that you need to disconnect, and then it just drops free.
The overhead panel for the headliner is removed next, and that’s just held in with 6 push clips, 3 in the front and 3 in the back, that you can remove with a trim removal tool.
The side panels are held in with a few more of the push clips, and then they can just be folded down out of the way. The one on the passenger side has a panel held in with 2 Allen bolts that needs to be removed too.
There’s not much to say for the Noico installation, I cut the panels to fit, then used a roller to press them on to the sheetmetal. Complete coverage isn’t required, so I just covered each panel with a roughly sized piece. Nissan included some dampening panels in some areas already, so I left those alone. It didn’t take terribly long to do the whole van, although it did require some effort to roll and press each panel on.
Since I probably won’t be touching the area behind the headliner again,, I insulated behind it using some 3M Thinsulate , and re-installed it in the reverse order.
All the panels sound much more solid now, and hopefully the insulation and sound dampening behind the headliner will quite down the road/wind noise a bit. That front panel sounded quite tinny before.
Finished result:
Now I need to finish installing the insulation throughout the rest of the van.
