Catalytic Converter Replacement on a nissan Altima

[@juanportillo2201]

May i ask you which bramd was the catalytic? I am about to install one in my car also from rockauto(eastern catalytic) and i am wondering if the heatshield holes line up. Great video keep it up

[@410AutoTech]

Rock auto it was the California emission and yes they did line up but the bolts will probably break so they did come with new bolts as well.

[@410AutoTech]

Great fit surprisingly!!

God BLESS you child for this VIDEO lol. Seriously, I was quoted $1900 for this job on my 08 Rogue but this video makes it easy to dive in. Got all my bolts soaking in PB blaster and broke them a little so they wouldn't be so hard to remove. Now all i'm waiting for is the convertor, belt, and 02 sensors to come in. Thanks a BUNCH man....damn I REALLY appreciate this!!!!!

[@hootinouts]

Excellent presentation. I've replaced the manifold/pre-cat on my s005 Nissan Altima twice already due to the out shell developing cracks and leaking. Now I am having the same issue once again with the third one that has been on the car for about seven years now. This time I am going to remove it and braze the crack to seal it.

Excuse me, sir. I just bought a 06 Nissan 350z because my 2010 Altimas catalyitic converter was throwing a code and couldn't pass emissions. I have searched and searched on where the catylitic converter is so I could remove and clean it. I was under the impression that mine was welded on. I can't say that you've saved me money. But you probably just made me some. Thank you.

[@Dwasabi]

This is the first video I’m checking out (just starting my research) because a mechanic I was talking to said the studder in my (06) Altima may be caused by blockage in the catalytic converter. He told me they usually get gunked up and all you typically have to do is take them off and break up the gunk, shake it out and it should blow the rest out and start breathing. Does this sound correct to you…? Also, MD mechanic? (Born and raised outside of Baltimore)

[@410AutoTech]

That definitely not what you do lol. But yes I'm in Maryland

[@hootinouts]

If your cat is gunked up I don't think there is too much you can do to clean it out. The monolith inside is a delicate ceramic material that can get damaged easily if you aren't careful.

[@khanjee75]

After installing new cat the po420 code will be disapear automatically or do we have to remove that code using some kind of device 🤔

Hello. Thanks for your videos. I have the same car. Everytime I look something for my car your videos show up. I have the check engine light on. The mechanic checked the error code and told me that the code is about the upper catalytic converter or the oxygen sensor on it. However the car has no problem when running. I guess when you have a faulthy sensor you should have other problems or symptoms. The car has 103.000 miles. Do you think the problem is the catalytic converter or the oxygen sensor? Thx
