How to take off upper intake manifold for 02-06 2.5l Altimas

NOTE: I am not a mechanic/technician nor do I plan to be. Do this at your own risk.
Update: Do not place the manifold gasket upside down, this will cause idling problems.
Alright, 3rd Gen 2.5l Altima and other QR owners, this video is for you. If you have a QR25DE, this is a MUST. Check your power valve (butterfly) screws, as overtime they can come loose and get sucked into your engine and cause internal damage. This is serious! So here's a video for you to get inside the intake and Loctite them down.
Here are two great write-up sites I learned from:
Nissanclub.com: www.nissanclub....
B15sentra.net: www.b15sentra.n...
This procedure took me four hours to do, with all the filming and holding the camera. It shouldn't take an average Joe no longer than 2 hours to do. It's so easy a gal like me can do it.
Clean everything with brake clean and when you screw in the screws, use Loctite or some other red threadlocker to keep them down.
If you have a question, drop it in the comments section below. Good luck on the intake :)!
Again, BT on NissanClub, THANK YOU for the awesome write-up!

***Sorry for the audio quality, guys and girls. This video was made back when copyright infringement was almost non existent and I could use any song for background music. Unfortunately, all of the songs that were used had to be muted. And i couldnt mute the music in the video, so i added a song from KZbin's free music library at the end, so be aware of a song playing randomly towards the end of the video... An updated version is planned.***

thanks for the update, you should pin the comment; I was confused why there was no audio

[@flash85396]

Thanks for showing this. I want to change my injectors but I believe I have to take this apart to get to them. I hope I'm as patient as you are. Not everyone is cut out to do this.

[@robertsegura7122]

I have to replace my injectors. Not sure if I should have my mechanic do it, or save the $ and go for it. Any advice or tips?

[@cheesebureger2501]

Did you ever replace injectors

[@satanbirmingham911]

Protect videos like this at all costs 🎉

[@XenomorphLV426]

I've never done this to my 06 Spec V. Been too lazy and Nissan "fixed" the butterfly issue in late 05 and all 06 models. But this video motivated me to do this. Props to you for doing this with one hand, while filming. I'm impressed.

[@05NismoGirl]

Thanks! I'm glad I could help.

[@mrexecutive1]

Thanks for the video. I checked screws on my 03 altima 117000 miles, they were good I took them out and put red locktight anyway. Pre cat was falling apart internally, I quickly replaced it with a chrome non-cat header, hopefully i saved it in time. To all of you think about doing these modifications, DO IT. I was hesitant now i might be paying for a remanufactured engine, $3500 installed. good luck!

[@05NismoGirl]

That's great! I did the same thing, replaced the cat converter with a catless header and locktited my screws. If a lot of people did this, there would be more 02-04 Altimas on the road and less in the junk yard. I still have to pay for a reman engine though. I have oil consumption still :( but not on a daily basis.

[@willprice7487]

Thanks only video I could find of this. Think this is why I'm getting bad mileage and car runs bad

[@MyCatInABox]

Hey- Thanx for taking the time to video this AND upload it. It was exactly what I was looking for (specifically, the vacuum lines and solenoid on the back of the intake.)

[@Andrew-rb4gs]

Just watched your video. Every step was filmed nicely. Nissan sure loves 10 + 12mm bolts, don't they? This would be a good time to change out any hoses and factory clamps. Also, before reconnecting sensor connectors put some dielectric grease on to prevent oxidation and fouling from dirt and oil. Thanks bro!

[@OLIVER949OC2]

Ya those factory clamps suck

[@wilo.2216]

Thanks for your video man it really helped me out. I have no experience but with this video I was able to do it and reverse it and everything is working fine. In my case I had to change a fuel injector. that was that was replaced by a mechanic and messed it up.

[@crystrezerex2life]

Snaaaaps that scared me....tunes came outta nowhere 😲🎶🎶😂😂😂

[@sbond1963]

Maybe I missed it but there are two layers of bolts. The big ones up the top and smaller ones down the bottom. Thanks again for the help

[@sbond1963]

Thanks for the video do I need to do this to replace fuel injectors?

[@copacetic_carguy]

Nice video did this to my spec v when I got it loctited all those screws

[@keithmhalstead]

Thanks for a great video. I am a beginner and this was a lot simpler than I thought it would be because of your video. Blessings.

[@adanescobedo6662]

Your video has been very helpful thank you!

[@jairw4635]

Amazing, I need this video Ty from Mexico

[@zykospid]

Thanks dude!! It’s was of great help!!👍👌🏻

[@theenlightenedone8573]

Liked the video very much! I will give this a shot this weekend. I hope it ends my search for the reason my car idles rough and misfires. By the way, I like the smooth music at the end of your video! Who is the artist? Thanks!

[@janelishernandez6503]

Tony Thompson is ur car still idling and misfires

[@rizchellsuniga4402]

Tony Thompson I have 2003 altima I replaced all 4 ignition coil packs and the idle is perfect

[@JoseGarcia-up6bw]

Thank you for sharing this video, God bless..

[@05NismoGirl]

+Jose Garcia No problem. :)

[@posneg-ut8ds]

great video !! just wondering if you put a new gasket on while you were at it too ? , if you did ,can you tell me the steps of you went about doing so,did you use gasket maker and/ or sealer ?, then lay the gasket on that etc , ? if you can, try to be as specific as possible , and the main question is should I even bother doing this on my car? ( locktite tthe butterfly screws to begin with ) ? . I know many 02-05? have had issues w theses screws , I have an 06 nis altma 2.5 am I out of the woods ,or should I do it ? thanks !

[@05NismoGirl]

I didn't put on a new gasket. I did put the gasket upside down though, which caused bad idling problems. But I put the gasket right side up and the problems were gone. When I did remove the gasket I didn't find any gasket maker or anything. It was just sitting there lol. If you have an 06 then you shouldn't have to do this because Nissan fixed this problem in that year. It doesn't hurt to check though.

[@Sroor2023]

Omg😵😵😵 do I have to go through all this I've dissasebellled every thing remaining alternator and put the engine on tdc, I want to remove the head with the intake which bolts to take off then ill do the rest for headgasket then dissasemble intake mainfold outside the car it's pita do it in this way

[@southsidekooly8602]

Correct me if im wrong but i dont think tht was intake manifold gasket that was valve cover gasket replacement. Jst for clarity

[@shayv1547]

No that was the intake the valve cover wouldn't have that many things to remove your valve cover gasket sits under the housing of your spark plugs(valve cover)

[@bangbang9643]

Could that cause water to get in with they all

[@Andrew-rb4gs]

Great video. Lighting was good enough. I will use this post when I need to do this job. At what mileage should I check for this brother?

[@_Circus_Clapped_]

mine has started this problem at 250K miles

[@juanbarraza5604]

Did you re use your manifold gasket? Did you removed the water lines going thru the throttle body?

[@05NismoGirl]

Yes, I re-used the original gasket and I didn't even touch the water lines on the TB.

[@juanbarraza5604]

05NismoGirl Thanks for the input

[@05NismoGirl]

Juan Barraza No problem :)

[@sleimansaab1628]

I'm having problems with my fuel injectors and I'm planing on swapping them this Saturday. For this to be done I'll have to remove the intake because the injectors are right below it. Do you know the steps to replace the fuel injectors? Anything would be appreciated thanks. Btw I have a 03 altima.

[@05NismoGirl]

I haven't messed with the fuel injectors. Go to NissanClub(dot)com to look that problem up. That's where I learned almost everything about this car.

[@yosemite6545]

Is this the same for a b15 sentra SER spec V

[@cerealphobe8440]

I'm sure you've done this by now, but yes. A bracket might be in a different spot but the qr25de in the Altima and spec v 02-06 are identical

[@donchito6281]

what is torque specs for intake manifold ?

[@mronemanband1]

tight 11 foot lbs

[@j1234567890v]

Where are the butterfly screws that need loctite?

[@eunicemontiel335]

No sound I am here guessing

[@raolito1980]

Damn that intake was dirty. I wonder what mines will look like.

[@johngrijalva8284]

I have a question i recently got my head gasket and valves done but their still fluid leaking into my cylinder 4 does the head gasket and valve job also include the intake manifold to?

[@DizastrousMindsShine]

John Grijalva it could be that your valve cover is actually broken from inside, mine had that so my cylinders would be full of oil.

[@raolito1980]

You have to change the valve cover. The gaskets around the tubes dry up and crack. Cannot fix you have to replace cover

[@DragonNB13]

theres nothing on the first link?

[@XenomorphLV426]

You didn't take off the throttle body?

[@05NismoGirl]

I don't think so.

[@OLIVER949OC2]

Cant see nothing

[@youngbucks6504]

2:41 what is the name of that hose ?

[@05NismoGirl]

A vent hose, I believe.

[@youngbucks6504]

Thank you

[@cody71200]

the music made it so I could not understand or hear anything you are saying

[@lowridingtrucks88]

Cool👍

[@LynxStarAuto]

Another poor owner falls victim to Renault screwed shitbox Nissan. How the mighty have fallen.

[@sircountmstrnvrdie5117]

I have fallen to sad face

[@aguilars1]

No sounds
