Panbacca Posted August 27, 2010 Share Posted August 27, 2010 I've just started exploring the underside of my 2003 lately, and I came across these interesting pieces. One just looks like a canister, which is dangling there with some sort of drain tube coming out of it. The other is a tube going up underneath the bumper where it seems to me like it has been cut. Anyone have any idea what these are? Can someone post a picture of theirs for comparison? This is under the DRIVER SIDE rear bumper. . Link to comment Share on other sites More sharing options...
01silvapathy Posted August 27, 2010 Share Posted August 27, 2010 Evap canister for your gas tank. Not sure what it does either Link to comment Share on other sites More sharing options...
Panbacca Posted August 27, 2010 Author Share Posted August 27, 2010 Ok cool. But is it just supposed to be dangling there like that by those hoses? Those two pieces I pointed out just don't look quite right. Link to comment Share on other sites More sharing options...
shift220 Posted August 27, 2010 Share Posted August 27, 2010 The drain on the left side is normal, just a air/water vent I guess. The other big item is the evap canister. It basically stops the fumes from the gasoline evaporating from entering the atmosphere. The system will purge the container at certain times and burn the fumes through the engine. I don't really know if it should be hanging like that, I have a 96. Link to comment Share on other sites More sharing options...
5523Pathfinder Posted August 27, 2010 Share Posted August 27, 2010 (edited) The part that is hanging by the hoses, is a water seperator. Its supposed to be attached to the bracket just abouve it in your picure(with the square hole). As stated, its for your evap system. It may have been worked on at some point in time. The canister is known to come apart and have small charcoal "beads" sucked up to the intake mainfold. Someone was just sloppy putting it back together. The other is a drain for your sunroof.

01silvapathy Posted August 27, 2010 Share Posted August 27, 2010 Mine has been dangling down like that for awhile, I zip tied mine up just to be sure it does not go anywhere. Heard that if it comes off it can set of a check engine light. Never knew that tube was a sunroof drain Link to comment Share on other sites More sharing options...

Thank you for the information. Now I can at least put my mind at ease. haha. I'll probably zip-tie that canister so it's not just hanging there.
