As a pro video producer, I want to thank you for taking the time to do these videos well. Good lighting, steady camera, and great awareness of not blocking the viewer's sight line. These are extremely well done and very helpful!

[@dial2fast]

Really appreciate your wonderful comment! Cheers!!

[@danbunting2481]

I'm a producer too. 40+ years experience. Al's right, extremely well done.

[@pepelepewpewpew3400]

I'm not a professional mechanic but I do minor repairs like brakes and change oil. After watching this well-made video, I am now confident enough that I can do the same. I'll just be needing that jointed ratchet and the money for the parts. Thank you Dial2fast, great job!

[@jdlalbertaboy]

Thank you very much!! I did mine in about two hours. Without this video I wouldn't have attempted it.

[@timseiple6882]

I know this video series is old, but so is my van :) !! What a life saver. Well organized, good lighting, clear instruction, good videography. Making the internet good again. Thanks man!

[@dial2fast]

I am happy to hear my video is able to help you. Have a great weekend!

[@MrPatdeeee]

If you haven't been told already; I want to tell you that you have a very clear and eloquent voice; that makes your DIY'rs VERY easy to learn. Also; you are a helluva teacher. One of THE best I have heard on KZbin. Wow are you knowledgeable when it comes to automobiles. Thank you kind Sir for sharing your talents with us. May Jesus bless you and yours always.

[@dial2fast]

Thank you for your wonderful comment!

[@BASavage81]

Well made video. This vehile is an example of why engineers need to be mechanics

[@josephplatter9033]

Your video was a lifesaver. First time doing plugs on one of these. Pain in the butt.

[@wichjr]

Thanks for this, I'm in the middle of this job and those green plugs totally stumped me.. now i know i can bend them without breaking

[@fritzgeraldgrandchamps4268]

I followed video 2, 3, and 4 to replace the valve cover on my 2002 nissan maxima (vq35de). I also had the Hanes Service Manual which confirmed the torque specs and tightening sequence for installing the valve cover. Make sure you have the proper torque wrench and a flexible wrench like the one used in this video to get to the brackets behind the plenum. Thanks a million for putting this together. The dealer wanted over 900 to do the job!

[@dial2fast]

Fritz, really appreciate your kind comment. Always happy to hear good feedback that my video was helpful.

[@ipleedafif8033]

Nice job! Freaked me out a bit cuz a friend asked me to watch this video and listen to your voice. They said we sound alike and I agree. Damn we do sound alike.

[@jrow8332]

Great video and I really appreciate your explanation of the specific tools required. Thanks for the help.

[@jtcusa7288]

your video saved me!! I didn't know how to remove those bolts from the egr tube! thank thank you!!!!

[@scottjackman6682]

Very well done thank you for all the tips.

[@mattmccandless3924]

This whole series rocked. Did it to my 2007 Quest. Took about 7 hours, but I am definitely an amateur.

[@audioamateur]

Such a high quality video thank you!! I'm working on replacing my rear valve cover for my 2004 Maxima

[@silvernblackattach]

Thanks for posting this. This is fantastic work. I still think it's a rather poor design from the maintenance perspective though (and that's putting it nicely). If you could have showed us the backside of that manifold after removal I think it would have put some of those rear attachment bolts and accessories in perspective. Many thanks.

[@dial2fast]

You are correct, showing the back of the intake plenum would help understand what needs to be removed. I also thought about it when editing the video, but unfortunately I did not record it. Thanks for the feedback.

[@jermainejohnson7161]

Thank You . This helps me a lot

[@Mochanics]

Very helpful video 👍🏾

[@TheChuyDewy]

Great quality video

[@Noctrl100]

Great video!

[@haroldgonzalez9424]

A good picture on the manifold to see every single bolt would have been helppfulll!

[@thinking-laaf]

It's a good idea to replace the $10 PCV Valve any time the intake plenum has to be removed...

[@rogue2309]

What size wrenches sockets etc are needed? Got to do the coil packs on my altima that has this engine.

[@johnaranjo2059]

hey man question, one of the hoses on my plenum seemed to have had gas in it? its one of the hoses underneath near where the plenum connect to the rubber boot

[@usaryder74]

Holy moly. That is a lot of work. I guess the same engine used on Infinity cars must be a lot easier to work with. That is a big a... engine. I better hire a pro to do this work.

[@elquetedijo]

Thanks for the video... very complicated motor to change sparks plugs. I was about to buy a Murano and now this video help me on my decision to not buying that model my mechanic will kill me hahahahah.

[@dial2fast]

The spark plugs are a pain on this engine, but you only do this every 100k miles, and the engine is solid. There are lots of good choices out there these days. Hope you find a ride you like.

[@jjsiegal1]

Good work man...!

[@dial2fast]

jjsiegal1 Thanks for your comment!

[@ccsluf]

Man, I'm gonna change my left side and see to what extent that slows my leak. Seeing how much work is involved here, I don't think I'm up for the right side on a vehicle with almost 200K miles anyway, and I sure as heck am not paying whatever it would cost (probably over $500) to have this done for me when all it will do is save some oil and keep my engine and driveway cleaner. Heck, oil is relatively cheap anyway. I'll probably switch back to conventional oil at my next oil change as well. That'll save a little and might slow down the leak from the right side a bit as well.

[@rosendoguzman6234]

Do you have to separate the rear part of the intake, or can you pull it all out as one piece?

[@smoothoperator6507]

What are the recommended torque specs for the upper intake plenum?

[@camronurmey4499]

Can use a 6 mil on egr studs as well. Just have some wrench sense and don’t strip em out

[@manuelsalgado8510]

What size socket did you use to remove the plugs?

[@azalvez9833]

awesome videos +dial2fast! I have a question. Have you replaced the water pump on your nissan quest or do you have a video for that? My '05 nissan quest its leaking antifreeze so I think its time to replace the water pump on it. Hope to hear back from you. Thank you and keep up the good work!

[@dial2fast]

Sorry I have not replaced the water pump. I believe the job is pretty involved as lots of work to remove the side cover. Check out these videos and should give you an idea: kzbin.info/www/bejne/o4mzeoqdqN6InsU and kzbin.info/www/bejne/lXPPgJZ4r9Wdh6M

[@azalvez9833]

Thank you for the reply back dial2fast​ and thank you for helping me with the other videos too I really appreciate that.

[@wimzrxsf]

Worst part of job for me was the two green plugs and the bracket spent hours on them.

[@rkneegordon6316]

This was a great series. I noticed the power steering hydraulic line is buried behind there, and mine is leaking. Is this also the best way to remove an replace the line? I don't want to have to go back there again.

[@maclandyouth]

+Arnie Gordon It helps, but I replaced my PS hose on my back, under the car. Took about 3 hours.

[@juniorkuilan4922]

I have a Nissan 2.5 pickup truck , i need to known how can I get to the coils.

[@michaelnagatoshi1830]

I didn’t follow the loosening/tightening sequence and specs. Oils is leaking worse than ever. Maybe I didn’t put enough silicone, too?

[@WorldlySurvivor]

Is this the same as 2007 Nissan maxima?

[@Devil3R]

This is why Auto Techs HATE engineers.

[@ddthames]

How do you get those green electrical connectors unplugged, that are in the back of the plenum on the passenger's side? Like you I bend that bracket open a bit to get the bolt out. Finally got the plenum out. It looks like wires chafing against the intake valve timing solenoid. I need to get in there where those wire bundles are and get better access to see what needs done to fix them. I don't understand how the connectors unlock. Any help? Thanks.

[@dial2fast]

If I remember, the green connectors had a middle tab that you can use a small flat heat to push on it and disconnect. I just don't remember it being an issue. Getting that bolt holding the bracket was the difficult part I had.

[@eh2688]

Put a flathead screen driver at the top of the clip push down and pull.

[@amandas.9519]

Wow, this was so much work for spark plugs. I made the mistake of checking out an Odyssey spark plug video first...big mistake. It was so easy!! I am afraid of what this is going to cost me to have fixed in my 05' Nissan Quest. I can't do it myself so paying someone is my only option. Can anyone tell me what a fair price for that is? I feel like I was overcharged when I had my water pump and timing chain replaced a year ago so I am cautious to spend too much again. I am considering just using this as a sign that it's time to trade up.

[@ganzoking]

Its going to run ya $400 - $500

[@HToWnRePPiiN]

Bro, I was quoted $285 just to replace my cylinder 3 spark plug.. I was so confused, a fucking $4 spark plug costing $285 to replace.. It's like they built these cars thinking spark plugs last forever! I'm so fucking pissed off, I remember a few yrs ago I had a Toyota Camry and I literally changed ALL the spark plugs in 15 mins.. I just had my timing chain replaced 3 months ago ($710, which is a huge discount considering I was quoted over $1200 by 3 different places) 4-5 months before that was the high pressure power steering hose ($328 parts and labor), just had my rear breaks and one of the rotors replaced 2 weeks ago ($115 parts and labor)

[@johnaranjo2059]

Big Turbo 91' Geo Metro the spark plugs are designed to run forever, and dont replace your spark plug until you replace the reason ur plug went your valve cover is blown and leaking oil into your plugs, the oem plugs are platinum and do last forever providing yku have a solid gasket in your valve cover

[@bbblahoo7]

I love harbor freight

[@LOV2XRL8RL]

4:50 what's the size of the Torx?

[@jorgelopez2102]

hello thank you very much for your video, I have a PO303, Cylinder 3 Misfire Detected, I pay a lot to somebody to change the spark plugs, but the error still there, so it must be the coil so I need to do it again, but with your video I think I can do it, the guy said that he found some oil in one of the spark plugs (3 or 5), so what I will need to do to fix that problem too? Do I need to change the electric harness? is yes what I need to do? Thank you very much. if you can give me some advice for the wet spark plug and harness too.

[@dial2fast]

If there is oil in the spark plug hole, then the spark plug o-ring on the valve cover is leaking. Those o-ring are not serviceable which means you need to replace the valve cover (as seen done in my video)

[@jorgelopez2102]

dial2fast Thank you very much, Do you think that I need to change the coil harness? I cannot find any information about it, and also no one that sale it. the van is 175K 2004. Thank you

[@dial2fast]

Jorge Lopez Don't think you need to replace the wiring harness unless it's cut or damaged. Many of these smaller unique parts can only be specially ordered through your Nissan dealer. If your wallet allows, stick with the Nissan OEM parts.

[@eh2688]

Replace your plugs to start, a little oil is not uncommon. Won't prevent your engine from working. To fix you need to replace your valve cover seals. Probably missfire due to oil being on the spark plug. I had a p0301 the other day, fixed it by replacing the plugs. I fount oil in cylinder 5. Permanent fix replace valve seals. Temp replace spark plugs.

[@eh2688]

dial2fast don't think you always need to go dealership junk yards or people parting out their cars are a good place to go to.

[@MTLJack]

I just did it two days ago, i strongly suggest removing the cowl or else , you'll be pretty much guessing which is frustrating ... there's also two more bolts at the back of the engine, its for the manifold , attached to the engine head, they are pretty much useless so i didnt even bother putting them back. Most stupid design ever.

[@Jayotero1]

Is this the same set up and process for 05 murano

[@dial2fast]

Yes, same setup.

[@jcookjo]

I have a 2002 Nissan 3.5 I recently changed the Intake gasket and now the bolts wont tighten down? almost like the gasket is thicker than factory an bolts aren't long enough!.. Help! , thanks

[@john1120]

Creation isnt an Ism sounds like u got the wrong gaskets

[@rodger6940]

Bro what would you do if you drop a the nut in the cylinder 6 it fkn happen to me I don't no what to do

[@Suicidegrey]

Do you use silicone on the upper intake valve seal plenum when finished?

[@dial2fast]

No, you should replace it with a new gasket when doing this service.

[@Suicidegrey]

dial2fast I did but there is an air leak an engine still shake I put new coils an spark plugs also new gasket covers with gaskets

[@dial2fast]

@@Suicidegrey Not sure why your plenum is no longer flat, but if you have to, put a bead of RTV silicone gasket around it.

[@Suicidegrey]

One guy said not to use silicone but if silicone is needed I will and also buy a new gasket ?

[@statortot11]

Looks like you had to remove wiper module. No video on that. But still good video. Thanks

[@mariahdeyoung2530]

3:27 whats the black round thing called and the pipe at 3:53

[@dial2fast]

+Scott Lanza The canister at 3:27 is simply called a 'vacuum tank' and it's part of the VIAS control system (variable intake air system). At 3:53, the pipe is called the 'EGR tube' which bolts to the EGR (exhaust gas recirculator) volume control valve.

[@MetallicAsian]

What hose was that at 6:00? Im having trouble identifying the exact name/specs. Ours is collapsed. Pm me please

[@dial2fast]

MetallicAsian Hey, sorry for the last response, was out all day. That hose at 6:00 connects the intake manifold to the rear rocker cover is part of the positive crankcase ventilation (PCV). I don't have a Nissan part number (service manual doesn't specify it). Best thing is to call your local Nissan parts department and they can look it up for you. At least my local dealer is super helpful with giving info on parts.

[@johnaranjo2059]

dial2fast my local nissan dealer sucks and wont give me part numners because i wont buy their over priced parts, and why would i order a part withoit a part number( dont know what im ordering) but courtesy nissan has a lookup by vin system and great diagrams all oem parts at a discount guranteed to fit if you go by vin! thats what ive beem doing after trying cheap parys from amazon, over priced aftermarkets from advanced suck when you can pay the same for oem at courtesy nissan. com

[@NEMOJA]

Your supposed to remove the green connectors from the bracket. Not remove the bracket itself

[@Autofixpals]

How in the hell is that engine that clean and corrosion/rust free. I did the eaxct same job and made a video about it on my channel (shamless plug be sure to check it out) and the vehicle i did the repair on was not half as new looking as this one. Man i wish all my customers cars were in that great a condition.

[@dial2fast]

Lol...No rust because I live in Georgia where it doesn't see any salt. It's clean because I am the only one that touches this car and no one else. A light rinse with water couple of times a year is all I do to it.

[@Autofixpals]

@@dial2fast Thats awesome. That thing is cleaner than a 3 month old New Jersey car..lmao.. good video BTW.

[@keniacruz7410]

what is the name of the piece you remove at 3:10? thank you in advance!!

[@dial2fast]

kenia cruz the small component I unbolted at 3:10 is the VIAS control solenoid valve. to the right of it is the vacuum tank.

[@KahwahShutseh]

[@linhnguyenba5418]

+Manila Kid How can you do it? As far as I know, the Maxima V6 also need to remove the manifold in order to change the rear valve cover and spark plugs, since the rear valve cover is under the manifold.

[@manilakid3]

+Linh Nguyen Ba My bad, I should edit my previous comment. But the 7th gen and I guess the 6th gen Maxima's are required to take out the Upper Intake Manifold to get to the rear spark plugs. My 5th gen Max doesn't.

[@Famcov215ify]

dside521 philly

[@eh2688]

I'm in nyc a little to far. It is a extremely simple job, they have better diys. The valve seal is a little more work then the spark plugs. You can have everything done in 3 hours roughly first time. Just make sure you have all the tools. 12mm 10mm 5/8ths spark plug socket, flat head, socket extender and a t30 torques. Just look at the plenum make sure you disconnect all the hoses. Make sure you disconnect the sensor clips. Completely remove to get access to the valve covers.

[@garnetdurham4643]

Top Plenum Rear Bolts are 12mm, Passenger Side one is 12mm, Driver Side One He takes off with short stubby driver at 08:55 in video is actually a 10mm bolt 😡 Stupid Nissan Engineers!

[@Pragmatist1st]

Car manufacturers design car parts to periodically fail. Then they stuff that engine in so tight, you can barely reach anything. They don't want you to be able to fix your own car. Then you have to bring it in so they can make $ off the repairs too. They get paid twice.

[@Osama84ca]

[@maclandyouth]

+Mike Zaldivar And you're talking about 100,000 mile spark plugs, so this might be a once per ownership thing. Doesn't make it easier, but puts it in perspective.
