Great work! One of the best "How To" videos I've seen. Thanks.
Wow, thanks!
inner fender joke was so so cool and funny, worth the watch!
Nice job!! New subscriber here! I have a 2005 Nissan Pathfinder 400,000 + miles! Yes! You read it right lol that I finally had to put down but wish I can get it up and running again (if it’s worth it). I had the catalytic converter replaced twice, new transmission, a slow running oil leak and maybe others that my untrained mechanic eyes can’t see!
Yeah, I did have to read that 400,000 again, lol!
Nice job what I like is that you took your time to do it right EXCELLENT
Thanks Mike!
Just from reading the comments I had to subscribe. Also hope this comment gets read as it is a few years old, LOL. I was searching for cats R&R VQ 4.0 Nissan Xterra “OR” model as I just bought at a very, very good price. She has 183k on the clock with good maintenance records and no transmission issues noted, (SMOD) but owners were convinced the tranny was shot by some advisor “friends”. The truck looked new & I have a 014 XS with 48k miles and wanted the locking diff, the wheels & maybe the seats, from the OR for my “S”. When I drove it, the tranny checked out fine best I could tell by the way it was running, but immediately heard the rattling along with a misfire, (ah ha) of a plugged cat. 4WD & locker good, no leaks & appeared truck was solid and did struggle to get it to 50’ish mph spitting & coughing terrible!! Oh, AND NO RUST!!! 😁 🤪 Plan to R&R pre cats, R&R suspension, R&R fluids, and hopefully have two solid Xterra’s. Interior is perfect except a tiny driver “in & out” wear spot. So all that said, (sorry for this “book” comment) That said, I have heard on the VQ4.0 that there is a negative pressure from valve overlap that can suck some platinum & garbage into cylinders... ?? Have you any info on this issue? I apologize this turned into a “book”, but you’re vid and especially your comments impressed me and you have a new subscriber.
Very nice read, and that would be something else if it was a clogged cat!!! Seems like you got a great deal, so keep us updated on what you find, and THANKS FOR THE SUBSCRIBE!!
The Vid was way funner than the job it self!
LOL
Nice Tim and Sylvia.
Got mine apart today. Found my resonator is plugged from all the debris from catalytic converter. So guess I can either replace the resonator or drill holes through it
Thanks again for the video! I got both the front and rear cats out. The front one was hollowed out and all the catalyst had flowed into the rear converter. I poured out all the remnants and powdered material. Is it salvageable? Can i clean out the rear or should i replace both?
Hey good vid. I have to change o2 sensors every year. I just put a whole new exhaust from the headders all the way back brand new and all new sensors and i already have to do it again. I think its because i run 87 and not 93 in it ... but its a beast of a vehicle.
I doubt it's the gas, but anything is possible.
First off, your videos are great! Ive got the same issue on my 2006 pathfinder. Quick question though. Would it be easier to cut the cat out then remove the remaining portions? What problems could this cause?
Did replacing the catalytic converter on the right side front turn off the check engine light for code P0420
THATS WHAT IM LOOKING AT
How u know the first one is bad and not the second one ?

Xterra 05
Done. But heat shield they screw up my bolts I snap one off and the lower 10mm bolt is rounded. Popped the shield off and gonna ride like that for few days. The main part is the problem fixed. Didn't see to much of leaks
Have you replaced that heatshield?
Hi my name is Horace and I have a panther finder 2005 Nissan with that same problem and took it to a garage and paid 900hundred dollars is that too much to pay
Did they do anything else other than change the catalytic converter?
Hey i have a question. I have changed out the shifter assembly and brake switch butcar still wont come out of park 2004 nissan maxima. What im i missing
Check your fuses and check to make sure you are getting the proper voltage and ground to the switch. Hope this helps
Love your perseverance.
THANKS!
What is the lifespan of OEM catalytic converters? I had both catalytic converters on my 2006 Nissan Pathfinder replaced in 2015. This year the P0420 Bank 1 code returned.
I did a few basic things like spark plugs, valve cover gasket, and air filter, but I suspect its either a bad oxygen sensor or an exhaust leak that is causing the P0420 code.
Cats usually last a very long time as long as the things you just mentioned does NOT exist.
I wanted to replace my front but they welded it to the rear converter
Could I ask were you got that neat looking magnetic light in the video?
Thanks
Sure, a great subscriber of ours (Big Bill) sent it to us as a gift, and THIS LIGHT IS GREAT! He got it from Harbor Freight, and I believe it was around $20. Well worth the money!
I took the shield and wiggled it up enough to get to the 3. Bolts I had a much easier time doing this from the bottom under the car
Thanks for the vid i have one on my rack now im changing this cat on the left side i did last week and it wasn’t bad this one is no fun at all and nissan has no published r&r method for this side unfortunately
Let us know how it turns out
So from this point in the video if you need to do the manifold which in my case i sold one due to the screws for the shield being broken.... take the engine mount loose on that side they give plenty of room to jack the motor up a bit you can then move the shield around alot more and get your manifold nuts and sneak the manifold out leaving the heat shield still in the vehicle! Thought i would give everyone a heads up this side is a real pain but it can be done
@@chriscash9313 Thanks Chris for that info!
Astral Auto Repairs no problem thank yall for the super in depth video i was so lost untill i watched this, had to brainstorm the manifold a bit
Hey, I have codes for both cats on my 05 pathfinder. Do you think it's absolutely necessary to replace both cats and all 4 02 sensors? Can I take out my cats and clean it and just replace the 02 sensors? Depending on how bad they look?
If you have P0420 and P0430 you need to replace the cats, but not the O2 sensors. But first, you need to find out why they went bad.
Any recommendations on where to start?
@@OnlineAutoRepairVideos - how many cats in total to be replaced? I have both 420 and 430 codes. I'm in the process of ordering the cats. Thanks in advance
Hell0 Tim. I have the same Pathfinder but an 06. I'm getting a multiple random misfire code. P0300. I've replace all spark plugs, valve covers and gaskets and ignition coils. Would a P0300 also indicate that i have a bad catalytic converter?
If the catalytic converter is clogged, it can. Also check for any exhaust leaks BEFORE the cats.
Astral Auto Repairs I did the the vacuum leak test with a can of carb cleaner. No change in engine response. I know using car cleaner on a hot engine. Dangerous!! But i had a fire extinguisher close by. Still misfiring. So I'm gonna assume bad cat. How do I know which one? Or just change both?
Change the cats as a LAST RESORT, because if that P0300 still remains, you will damage the new cats!!
I got the same problem what did u find out
Great video I also noticed that the upper ball joint Boot was cracked might need further attention
Thanks Willie Little, I will definitely let the customer know!
45:35 best idea....genius of your lady !! Get out of the rain lol
LOLOLOL!!!!!
Man I have 06 nissan pathfinder se ..with code popping up p0301 or p0300 change plugs and change o2 sensor..any idea what else it could be ?
Ignition coil(s), ignition wires, bad fuel injector...
@@OnlineAutoRepairVideos I changed plugs and the coil that stated it was bad lost hesitation while driving xmas eve wouldn't go past 40 mph up hill
@@serges1871 Do you still have the P0301 and P0300?
@@OnlineAutoRepairVideos yes I just got sensor in yesterday and put it in it was a mess to get to it but I did
@@serges1871 Yeah they can be a pain!! Check the fuel injector, or even better, do a compression test on that cylinder.
hi, great video - very informative. I have a question. i have 2002 pathfinder and i pulled down the wheel cover along with another piece that was in there on the wall side. thing is, there seems to be some kind of other steel wall or something shielding the engine from access that is not like what you have in the video. question is, is that somehow removable ? i tried to get to the 02 sensor from the top with an extension but it is so tight that i cannot even get the 02 socket on it evem with an impact socket. it looks like i can probably remove the catylitic converter from underneath and perhaps get in that way (i have a 04020 bank 1 code so i figure the cat is likely bad but was gonna replace the 02 sensor too since i was going in there anyway. thoughts on best way to approach? its weird because it seems like the layout for the 2002 pathfinder including 2001 to 2004 are different than 2005 and beyond and also 2000 and prior. thanks!
Thanks John, but I'm not sure how to go about that one if they are different. There aren't any other CZcams videos out there for your year?
@@OnlineAutoRepairVideos i have looked for a 02 sensor change video for a 2001-2004 pathfinder but i cant seem to find one that shows this wall issue. i think the 2005 is different on that side wall. baring that, i wish i could find something to show how to easily access it from the top. i was going to try a crows foot socket next.
@@johndonohue7746 WOW, out of all these CZcams videos, nobody! I have to hurry up and be the first one to do one, LOL!
good fix on that screw tapping, and the fasteners always seem to end up missing.
It was funny that the other side was missing just as many, lol!
Is this the about the same process for an 02’ nissan pathfinder??
If it's the same engine, it may not be the exact same, but it will be VERY close.
Part just came in today, going to use this as a reference. Thank you!
@@Jaymes222 Great, let us know how it turns out.
2002 3.5 engines have a similar process. The o2 sensor is not mounted into the Cat itself, and I did not have to take the fender out because there isn’t any locknuts on this specific 6 bolt Catalytic Converter so all was visible from under the vehicle. The only trouble I had was getting those 6 bolts on the old cat loosened and with the amount of clearance I had since it runs up near the frame it was almost impossible to break them loose. Thankfully, a cordless 3/8 impact drive with a long extension makes it a whole lot easier.
@@Jaymes222 That's great, glad it all worked out for you.
Same problem with a friends Pathfinder
Are you doing a video on it?
@@OnlineAutoRepairVideos I have to do a little more of research because it is saying that both cats are bad.
This one had the same thing. We had to do both. This one had a misfire that damaged both cats.
@@OnlineAutoRepairVideos That's the thing. This one doesn't have a miss fire. I watch your video a few times.
Okay Hulk, put your scanner on it, and in the data stream, while the car is running, and warmed up, let me know what the long and short fuel trim is.
Thumbs up to you Timmy, another great video...👍👍👍
Thanks!
Where was the cat for this video bought from?
Not sure, the customer bought it.
Is bank 1 the passenger side??
Bank 1 is the passenger side.
THANK YOU
After she said Kevin heart, now I hear it ! 😆
LOL
When sylvia asked you about your hulk like strength you should have said they need a GYM pass lol ahahahh lol
LOL!
Would there be a better way, in retrospect, to get those upper bolts out to pull that converter out easier without having to go through so much trouble? Idk if that double nut trick to spin those studs off would work and then the whole converter would slide out easier, what would you think. I am doing this exact job tomorrow so I guess I will find out, wish me well. Thanks for your information and help with these videos.
Hey Tyler, anything is possible!! We try to teach people that no matter how you do the job, as long as the end justify the means and you are happy, then that's all that matters. If you try that, BE SURE to let us know how it works, that trick might help someone else out, THANKS!!
Ok. Soo.... wow. Where do I begin. I started off really well. Got to auto zone since my cat came with no hardware, the start of the end, unscrewed one bolt to get new set with similar size. Got home with supplies. Unscrewed all top three bolts and the two on the bottom. Seemed fairly stuck and the idea I had seemed to not be very plausible with the angle, so I went to the rear cat on the same side and unscrewed both of those fasteners which were rusted on and just sheared off. I was able to shear both bolt heads off and shook the whole thing and it all fell apart. Pretty quick. I then realized I couldn't use the nuts I got since the two studs were too big. I put it back together loosely to go grab two nuts from the hardware store. Couldn't match the size. I tightened the rest of what I could since it sounded terrible. I feel like I will have to take it all back apart to find the right size bolt which I could have done if I just took it out of the box or if the piece of junk came with them. Frustrating. What would have taken about 2 hours now is still not done. Oh and the kicker. Since I left the o2 sensor dangling, it melted to the side of the cat and now I need a new o2 sensor as well (which I should have got anyway. I just kinda did this hastily since my inspection is due by the end of the month)
Btw. I did all this work without jacking it up or taking the tire off. All I did was take the splash guard out, unhook the up and downstream o2 sensors, and unscrew the 7 bolts holding the front and rear cats to each other and to the manifold and exhaust tube, respectively. If the damn thing only came with the hardware. Ughhh
@@tylerfochtman1578 Now THAT I did not expect!! Where did you get the cat from?
I got the cat from rock auto. It was a Wagner 83699 (C.A.R.B. compliant) I called and they said the nuts for the studs are 10M 1.25. I actually bought those and tried and I guess I boogered the threading up trying to take the off since, like you were saying, the way that is makes it a pain for anyone trying to take that off next time. But thanks for your videos. Really helped a great deal. Still have one bolt that needs to be tightened so I am kinda up shits creek. Might just try to muscle it on. Otherwise I will try to use a tap and die to clean it up and get the right nut on it. I just didn't want to take it back out, but if I would have it would have been a lot smoother. I might have to end up doing that anyway to clean the threads. Really a bummer. Inspection is due by next week. Doubt I will be able to complete a drive cycle and see the light stay off. Let's be optimistic though. The more I look under my Nissan, the more work I realize it needs.
Put some Ajax on it
BOOM UNO 1 Bammmmm
Mark another one up for Sylvia. lol Good Idea or did you read the directions. (No Real Man would Read the Directions) lol. Oh darn, Timmy went to Plan A.
Yep, had to revert to PLAN A
