Solved. See post #6 of this thread. There are two bolts to remove, rather than trying to disconnect the tube.
-----------------------------------------------------------------------------------------
I need to remove the air intake snorkel to change my radiator.

This is probably going to sound like a dumb question, but the pictured connection below is putting up a bit of a fight, so before employing brute force, I figured I'd first check here so I don't break anything that shouldn't be forced. I looked around the .org, my Haynes, and elsewhere and there's no details in regarding removing this part, so I assume it should be an easy job, and I'm just somehow missing the obvious.



Is there a recommended route to take, be it red or green? Is there a special tool I'm missing?

 

There are a couple bolts holding the box thats near your green circle.

 

Well, in the mean time I just started ripping stuff out to get the job done. I'll probably go ahead and clean my throttle body with acetone or kerosene while I'm at it since I'm there.


Edit: Thanks schmellyfart. I didn't see your post until I posted this posted. I'll take a look for those bolts.

 

You shouldn't have to remove the resonator box-I would always just remove the snorkel section and it just pulls off of the J tube there. You shouldn't have to fight it!

 

If you press something blunt into the slots that you have circled and push the lock tab down/in, the pieces will come apart. Just do the lower one in the green circle.

 

Thanks for all the comments guys! I appreciate it and am marking this thread as Solved.


I found, after my exploratory surgery, that schmellyfart was right on and there were two bolts holding in the snorkel, their locations pointed out in the pic below. So to fellow newbies that may be reading this thread in the future, these are the only two bolts that need to be removed to remove the snorkel. Why not just disconnect at the red or green circled areas in the pic in the original post? Because when I had the whole snorkel bit out I found those tube connections twist off readily, but would be a royal pain trying to pull straight out, at least for me it would be.



I also found there was some residue where the snorkel tube part connects with the air filter holder box thing (I'm sorry if you're getting lost in the technical jargon there). Pic below is the area I'm describing. It looked like the weathered remains of double sided foam tape. Pic is after I had rubbed it off.


Is any sort of special foam tape or some such supposed to be used there? I just used a bit of single sided foam tape I happened to have from an old hobby. Not sure how it will hold up...



Fellow newbies, also note:
Unless you are doing a complete coolant flush, you only need enough coolant to fill up the new radiator and for me that was just slightly more 4 quarts worth. Don't make the same mistake I did and buy 9 quarts worth.

And a word to the wise:
If you aren't using 50/50 premix from the store, be sure to premix before you start pouring into the radiator. I found out I only need just over 4 quarts after pouring in a gallon of straight, undiluted coolant.

 

I have taken mine off several times and I just take the round tube off and leave the square part alone.

I don't know for certain if the foam that Nissan used was double sided, but I think that single sided would be fine. My only concern with a replacement is that it be made for wet, outdoor conditions.

 

please for your own good, buy real Nissan (or toyota or honda) coolant. the stuff at the parts store contains silicates that will cause you to need a new water pump over time. also, do a complete flush. your coolant has broken down by now you need to flush it to get out the contaminants. the new fluid has to coat the new parts as well. this keeps your system in shape it is well worth the $.

I guess that's one of those YMMV things.

Yeah, I found that out earlier today, about a day late. I was so focued on getting the radiator changed, I didn't read all the browser tabs I had open relating to coolant. Looks like I'll be doing a coolant flush in the very near future. At 100k, it needs it anyway I'm sure.
