Intake Plenum Removal

[boomer3]

I was driving the other morning, and noticed my temp gauge spike up.. Pulled off the road, and realized I had left most of my coolant on the road behind me. Always a fun way to start the day!
It looks as though it's a coolant hose somewhere under the intake plenum, but as most of you know, it's impossible to see anything under there, (has anybody else has blown a coolant hose in this area before). I've been trying to take the intake plenum off, and it's a tough job. I've taken off the 3 vacuum hoses at the back, and pretty well every bolt that should hold the intake on, but still cant get it off.
This is where you guys come in. For those of you that have taken it off while in the car, do you have to drop the AAC Valve off the bottom of the plenum before it will come out? I just drained the oil and am taking off the oil filter to give me access to one of the bolts that holds the AAC in, but i want input before I go further.
My coolant system was ready for a flush so long ago it's not funny. I'm sure this contributed to bad heating inside, and maybe even helped this hose to blow out...

I blew my heater hose, it sucked. Then I decided to put all new silicon hoses on my new engine. Did you unbolt the AAC? Just give it a good tug and It comes off fairly easy.

when i pulled my plenum i took it off. there are also a lot of misc bolts under the plenum.

Mcfly can do it in less than 30 mins.

remove the battery and you will be able to get in there with a 1/4" drive ratchet to remove all lower hardware

Mcfly can do it in less than 30 mins.

i can now too, had to take it on and off like 6 times one week troubleshooting fuel leak

So I don't need to take the oil filter out?? One of the bolts I was trying to get out bumps the filter when trying to drop it out of the AAC. Maybe I'm not understanding how the AAC comes out. I thought it drops downwards off the intake. But I also see bolts on the side of it..
Basically I've got everything off but the AAC, and need advice how it comes out.

There's three 12mm bolts that hold the AAC on the plenum (bunch of other 10mm bolts holding fuel line, dif. air line, etc.) The AAC wont drop off the bottom. It just hangs out there because of the lines that are attached to it.

Alright, thanks for the input.

Would you guys recommend replacing most of the hosing in there (coolant, fuel, and vacuum)? I'd wager it's all original. I know what hose I could use for fuel lines and coolant, but not so sure about vacuum. If i used standard hose for vacuum lines i'd be a bit worried about gas fumes wrecking the rubber after a few years.

yea if you can replace them do it. Also be sure to replace the intake gaskets atleast on both sides of the throttle bodies.

[boomer3]

Yep, i'm in the process of trying to locate intake gaskets, and the AAC gasket. I was told I could get them through local nissan dealership, but don't know how to reference them!

I also don't know what hoses I can use. We'll see what part source or piston ring(lordco) has to offer me.
