BTW, you don't need to cut or remove the heat shield. Unplug and unclip to O2 sensor wire first. Then, after unbolting the shield, lift it up on top of the coils. You have to shove it up there and tweak it slightly. You can lift it high enough to get to all of the manifold bolts. When you're done, pull it back down and bolt it back on. This works on both sides. It's how we do it at the dealership.

[@AaronHinesAuto]

Thank you for this info!! U the man

[@kill2ski]

Can I remove it entirely this way without cutting it up?

[@aaronbritt2025]

@@kill2ski You can remove the heatshield entirely, but you'll have to bend the s*** out of it.

[@yungavalor3192]

@@aaronbritt2025 possibly stupid question but would I NEED to replace the heat shield with a new one once I replace my manifolds? If that is too hard to do I don't want to waste any effort. My new manifolds didn't come with one.

[@aaronbritt2025]

@@yungavalor3192 no reason to completely remove your stock ones. You unbolt them, push them up and replace the manifold. Then you pull them back down and bolt them on the the replacement manifolds. It's actually harder to completely remove the heat shields.

Thanks for the video. I was able to replace mine in 19 minutes also

[@lcar9871]

WOW Aaron -- Great video!! - Thank you sir!! I was just looking at this job yesterday - 2008 Pathfinder with (I believe) the same VK56DE V8 engine. It needs a PS pump so I have the inner fender off for that. It also developed a leak in the passenger side exhaust manifold. I'm looking at the engine and reading the Service Manual (which has me removing the entire front drive axle assembly) -- thinking there HAS to be an easier way, and you just confirmed it. I found your very well done KZbin video this morning. You even list the needed tools. Very thorough indeed! Of course here in New England, the heart of the rust belt, there will be a lot more cutting, cursing and torch work. Maybe some welding too - the exhaust flange bolts look like toothpicks. Here's hoping the manifold fasteners come off ok. I will be sending a small donation your way and hope others are doing so too. Videos like yours are so helpful in so many ways. In this case it confirmed my thoughts that the manifold could MAYBE be repaired this way VS the Service manual method of pulling the whole front drivetrain out. Thank you! Larry

[@emiliosoto6545]

So I just did this job on my titan it has 220,000 miles on it and the bolts look like they havent been removed since day one. I used 2 cans of BP blaster and it took 3 days total to do the job as it took one day to just take the bolts of and another day to remove the old headers and reinstall the new ones. Day 3 was looking for the lugnuts my father in law lost and I had to buy new ones. So to sum it all up never doing this again. But thanks for the video it was helpful. 😁👍🏻

[@edwinthomas618]

Excellent video. I used it as a reference for my 2006 Armada 2wd on Bank 1 (LH) side. Take top of air filter box and flip over on the engine to get access to 2 motor bolts. I separated the steering joint to the steering CV joint. Trying to take the lower portion that connects to steering tack was an issue since it was splined and I didn't have a tool to get it off...so I left it. Regardless I worked around it...if you have huge hands it might be an issue. The heat shield came off without cutting it as it slide out from the top of engine compartment. My manifold bolts were rusted a little and I soaked them with CRC Knocker Loose over night. I took my time and they came off except for 1 bolt that needed heating. FYI... If you are doing one side and lifting the engine....my suggestion is to jack up the truck level because when placing wood under the oil pan and trying to jack the engine when it is tilted is not a good idea because there will NOT be direct contact across the oil pan when jacking up engine. It took me a day and 1/2. The little Milwaukee rachet was a life saver. I did a little things differently but your video was so helpful and a life saver from $1700 being paid..thank you sir.

I hadn't thought of going in from the wheel wells, and also now own an impact 14mm pivot socket to make the job easier. Fortunately, I'm experienced enough now with breaking things on vehicles that I only rounded off one bolt partially before I said "This isn't working..." and came to find this video!!!

VERY WELL DONE VIDEO! Nice balance of detail! Nice touch listing all of the tools required, that 7/8 wrench had me curious at the beginning. Excellent that you pointed out using new OEM nuts and gaskets, that's a DIY nightmare waiting to happen, strip them off half way and then have to wait for days for the dealer to order them. The length of the video was perfect, you edited the unnecessary parts, and didnt talk forever about things that are obvious! I did catch one edit that made me chuckle..... that first O2 sensor... you said something like.... just press the release and pull it apart... you fumbled a little and then the video was cut and magicallyit came right apart!

[@felixFPVDrone]

Great job! Excellent tutorial special for those of us who have Nissan Armadas/Titans. My check engine light came on at about 100k, I had the mechanic check for codes. He told me more then likely the catalyst converters need it to be replace. The more I follow this issues in KZbin, and other forums it leads me to believe my exhaust manifolds maybe crack (I haven’t actually inspected them). However, it seems Nissan has done a good job building heavy duty vehicle, but some of their OEM parts need improvement! Again thx!

[@dakotacresswell7270]

felix44860 just checked mine today and sure enough a huge crack around one of the tubes, getting it repaired and hopefully the issue is resolved, repairing existing headers is more cost effective than replacing

[@lovelife3628]

They use aluminum when they should have used cast iron. I have heard they can weld the crack rather then full replacement. Some shops can weld them without taking them off.

[@kill2ski]

@@lovelife3628 I was thinking about welding mine, how much did they charge you? My passenger side is a little noisy but not bad, been like that for 3+ years since I got it. Wouldn't pass emissions even though I have no codes or I/M readiness, this is BS!

[@blakeallen2189]

Any reason you didn't use the impact gun to remove the 8 nuts on the manifold? It seems like using the impact gun would prevent the chance of rounding the nut (not having to push the breaker bar (keeping it tight on the nut)while trying to turn it), but I was curious to get your input. Great video.

Great video. I have a 2005 Titan with all the original exhaust components besides a cold air intake. My question is what kind of sound will this make if my headers are bad? My truck is lifted 6 inches and has all terrain tires but I feel it's gotten louder inside the cab this past year even after I got new tires not that long ago. I have 190k miles and it does not show any warning lights on the dash. I'm in Avondale AZ so if your still in Surprise I would be willing to drive out to you and you tell me what you think in person.

[@kyflyboy965]

Thanks for this video! I just put new manifolds in my ‘06 Titan 4wd. I am not a professional mechanic but have done the service on all my vehicles for 40 years. This was one of the most frustrating jobs I’ve ever done! If I could offer any advice to anybody else thinking about tackling this project it would be to remove the 4wd differential (axle assembly), the frame cross member, and the motor mounts. I needed to replace the lower a-arms so I was already into it and had the steering knuckles already off. After I got the a-arms off I went ahead with the manifold replacement while I was at it. After doing the passenger side, I took a good look at the drivers side and realized it was gonna be a nightmare unless I removed the stuff I already mentioned. After taking those items off and finishing the drivers side, I wished I had done that first before even doing the passenger side. It made it much easier!

[@Matty-_-Patty00]

Just replaced my OEM intake with a K&N Series 77 filter (checked multiple times to make sure its snug and not leaking) and ran it for a day then the SES light came on. Looked and seen a P0174, tried cleaning the MAF sensor and erased the code then after driving for a bit with my scan tool connected a P0172 code came up checked for vacuum leaks nothing to report there although I did notice the crank case vent hoses didn't have any clamps connected and were very loose to pull off the valve covers so put on some clamps erased the code and going to see if that worked tomorrow. And while I put the clamps on I decided to get under my truck and listen for any leaks in the exhaust or the headers, sounds like above my upstream CAT's there may be a crack somewhere. It's hard to hear from the radiator fan but I think that might be just the problem. It sounds a bit louder on the passenger side than the drivers side. Might as well go with some JBA's and straight pipe cat back if that's the issue :) If you have any info what it can be happy to read out the possibilities and check it out. Edit: Also going to replace the Crank Case and PCV hoses to make sure. They've seen better days haha!

Is there shorties(not stamped manifolds) available out there with cats and flanges on already?(bolt ons).. only finding longtubes stock manifolds cats and open end shorties..

[@alouiciousjackson5812]

Those last two bolts can be removed with a wrench. Place the 14mm box end on the nut, and place the box end of a slightly larger wrench on the open end of the first wrench. Also, to prevent future failure of the cat a proper break-in procedure should be done: after idling for 5 minutes, run it up to 1500 RPM for 2 minutes. Then let it cool completely. This expands the catalyst material.
