The factory vapor canister rattles. Here's how to fix it.
Underneath the rear diffuser of both the sedan and the coupe is a set of emissions components attached to the underside of the spare tire well. You can access these by removing the two nuts and three bolts with a 10mm socket and pop the two plastic retaining tabs with a flathead screwdriver.
https://cimg0.ibsrv.net/gimg/www.myg...7f94dbb620.jpg The main component anchoring everything down is the vapor canister - which looks like a black plastic box with three hoses connecting to it. The vapor canister is held in place by a single bolt (12mm head) and a rectangular slot that fits loosely on a metal tab coming off the underside of the car. This configuration allows a fair amount of play enabling the canister to rattle and make unnecessary noise. https://cimg6.ibsrv.net/gimg/www.myg...3052603c5d.jpg You can easily eliminate the noise with some foam tape or what I used: 3M mounting squares (essentially the same thing). https://cimg5.ibsrv.net/gimg/www.myg...0c8d0ba77c.jpg Remove the 12mm bolt and place a solid object underneath the vapor canister to support its weight. I unplugged the two sensors, but there is enough slack that this is not necessary. https://cimg8.ibsrv.net/gimg/www.myg...87d4b52774.jpg I placed a single mounting square on the top side of the metal tab attached to the underside of the car. I left the adhesive backing on the exposed side and this combination ended up being perfect for eliminating all wobble in the vapor canister. https://cimg0.ibsrv.net/gimg/www.myg...aa3e059087.jpg Here's a shot of the vapor canister reattached. You can just make out the white mounting square in place now (see small white circle in center of photo). https://cimg7.ibsrv.net/gimg/www.myg...36a8996c26.jpg As an extra precaution, I trimmed some pieces of a mounting square to eliminate the play and rattle in this hose catch - because it was super noisy as well. YMMV. I don't care who you are, this is MacGyver-quality work right here: https://cimg1.ibsrv.net/gimg/www.myg...484d5f8c32.jpg That's it. You're done. Now just reinstall your rear diffuser and cruise your neighborhood revving on anyone within earshot. https://cimg4.ibsrv.net/gimg/www.myg...0a12bf949a.jpg |
You need to do more write-ups...well done!

Emissions components? Lol can I take it off and not get a check engine light? Wonder how heavy it is?

Very nice. In what situations were you hearing the rattle?
