I replaced the wrong cat first (driver side), busted those tiny excuse for bolts on the heat shield so chunked it. Found out that I replaced wrong cat so I went and bought the passenger and just finished it. I loaded up your video to show the guy at O’Reilly he is an idiot for telling me driver side and stubbled upon the holy passenger heat shield in your video. When I saw you cutting it was when I got stuck trying to take it out. I didn’t have shears, took me two hours to wedge, pry, beat and cuss at to get out. The rest was easy as driver side. Good video man thank you. Sorry for long comment.

The two studs the mount the rear cat to the front cat can easily be removed with a 10mm torx socket, which will make life a lot easier for u.

[@AGuyandHisProjects]

What year is yours? I don't remember that on mine. I believe mone were flat heads.

[@eminiscalperpro9729]

@@AGuyandHisProjects mine is an 05 xterra. on one end of the studs, the end the nut screws on to, is what looks like that of a torx bit head, it's 10mm. I recently had an exhaust leak at the flange between the front converter(the one you changed) and the rear converter. I wanted to change the O-ring gasket, but the previous owner had welded in aftermarket converters, so the rear flange, where I would normally unbolt the rear converter, so that I could move it back enough to get passed the studs to drop it down and get to the gasket, was not there, it was all welded together. I put the 10mm socket on my battery impact and popped the studs right out, allowing me to drop the rear converter enough to get the gasket in. if not I was going to have a tuff time dealing with it. Did you leave the exhaust manifold without any heat shield and did you have any issue with that? I'm thinking of leaving my passenger side off and maybe wrapping it with some heat wrap, when I eventually replace the front cats. Thanks for the video!

Fuel pump went out, had that changed out, Air Con went out, new compressor. Now the cat. converter is bad at 103,000 miles. Went to 3 different muffler shops and all said same thing, too much trouble and don't want to break a nut or bolt and be held liable for that.

[@todbnla]

Good Job, can you put the part numbers or links to the different exhaust gaskets? Also, was the new hardware you bought grade 8 metric or standard? And 1 suggestion; when you torqued your lugnuts, you should always use a criss cross pattern to spread the load I was always taught YMMV! ;-)

[@AGuyandHisProjects]

As far as part numbers I will try to start stating them during videos as I think that would be a good idea indeed (let me look through my purchase history and I will get back to you on that later. The hardware I purchased I bought grade 8 and would recommend doing the same as it is a high heat area. The lug nuts I agree 100% and typically do the star pattern with impact (16:32) then i count in a circle with the torque wrench to make sure I dont miss any.

Thanks for watching and glad I can help! On my frontier most of the o2 sensors are still good well above 200k miles. If you want to save yourself the trouble of doing it later than yeah go ahead...however you typically don't need to.

[@Mocconagames]

Yes there are two sensors. Four, actually, two in front cats and two in back cats. As you can see there is not real big to get there to sensors, it's like 20% of work, so I'll recommend don't replace thing if it works well. Just unscrew it in 2-3 stage, first when you turn it one time - if it goes easy, go ahead. If it stuck really hard as in this video, don't rush, use thread oil to spill it in between sensor and cat.conv., wait extra 20 minutes and continue.

So you went a year with a bad catalytic converter? My service engine soon light came on a few weeks ago, and just found out today that’s the issue. Wondering if its okay to take the truck to the beach (4 1/2 hour drive) before having it replaced?

[@AGuyandHisProjects]

Keep in mind I am not a mechanic. With that being said yes I went a long time with a bad cat. I don't remember the exact numbers but I believe that your check engine Soon light will come on when the catalytic converter as at less than 95% efficient. Keeping that in mind if your cat is mostly good then it's not going to hurt anything to keep running. What will hurt is if your cat has fallen apart and is clogged up so your exhaust can not flow

Did you try the cleaners and just changing the O2 sensor before just diving into the catalytic convertor?

Sometimes you can get lucky. I've found that the code always eventually come back. Gets old and expensive replacing everything lol. At that mileage their going to go eventually anyway. You can test them as well if you are worried about it though, they are expensive

Could be gasket between cat and manifold leaking ..or oil running down from the valve covers on to the o2 sensor saturating the sensor with oil..and also do a livedata voltage reading from the o2 sensors.. youtube explains the live data part..

Hay brother how long did it take you

[@AGuyandHisProjects]

Oh shoot, it has been a few days since I did that one lol. I'd guess a couple of hours, tops. It is a fairly straight forward and easy process on this one.

What size o2 socket is that ?

What was the cause of you having to replace the Cat? Bad 02 sensor or any other issue?

[@AGuyandHisProjects]

Thanks for watching. When your cat drop below something like 95% efficient it will trigger a check engine light. I have emissions control where I live so didn't have a choice but to fix it. Some will tell you to replace the o2 sensor and it will erase the code, however that I have found to only be a temporary fix.

@@AGuyandHisProjects mine was showing p0420 but it comes off and on randomly?🤷‍♂️ But its not running too good it looses power so I think I need to replace my catalytic

[@AGuyandHisProjects]

My check engine light would also come on and off intermittently at 1st before it became solidly on . I am by no means a mechanic but my truck even with a slightly badd catalytic converter still ran just fine

[@Tumusica311]

@@AGuyandHisProjects thank you I will change mine soon.

Sweet

Someone just stole my catalytic converter on the driver's side. Cut it right out.

Cat converter amazon link tells " "This does not fit your 2007 Nissan Frontier"

This is interesting. Not sure what/if something changed between 06 and 07. Just brought it back up and still shows compatible with the 06

To anybody watching this video hoping to learn! This video is 100% a guide showing you what not to do! Oh btw Nice technique torquing your rims down in a circular pattern, I guess your research department found that tightening rims in a crisscross pattern was a waste of time!

[@AGuyandHisProjects]

Thanks for watching and the comment! Please work on your vehicle at your own risk.

[@NeverEnoughPyro40]

The heat shield is not all that important you say! I really hope you stick to only working on your own vehicles and nobody else’s! Only someone with a lack of knowledge would say something stupid like that, I guess Nissan just put it there for looks!

[@AGuyandHisProjects]

Thanks for watching! I am not a mechanic nor have I claimed to be. I have experienced zero negligible side effects.

[@benladin626]

In this case it's not important. I replaced mine with an after market one and trust once the bolt snaps off the heat shield there is nothing you can do about it except but a new exhaust manifold which cost alot. So I left mine out and everything is fine. I've been running with out a heat shield for years and everything is OK. Look at performance headers there's no heat shield when you install it. So you'll be ok

[@Pr0ph3cy-k5z]

@@AGuyandHisProjects No worries bruh. IF you were to experience excessive heat around any wires or hoses, just wrap the wires and hoses with heat wrap tape and done!
