2010 altima 2.5L came in with a Check engine light on and DTC P0420 catalytic efficiency below threshold bank 1. Very simple to diagnose (see end of video).

This video is showing how to Change the Catalytic converter on a 2007 to 2012 Nissan Altima with a 2.5L 4 cylinder.
It is usually Very loud in the shop so there won’t be any vocal direction. Trying things a little differently on this video. If you prefer at least a voice over please leave your comments and suggestions down below.

Cats went out due to a valve cover leaked oil leaked into the spark plug wells caused my engine to misfire ended up ruining the cats cars at 180k so it should be changed for the age about to do the job on it once I get the parts, do you recommend replacing the o2 sensor?
This guy covers it all, he is awesome not to mention a professional
Awesome video. I have an 07 that has an exhaust leak in this same area. I hope its as easy as you make it look. Good job. Cant believe the customer didn't want to replace that belt..lol..
Anybody know where to get a converter for a cheap price for 07nissan Altima 4 cylinder
Hi what type a tool do you use to removed the serpentine belt
AFP… what tool did you use to get that piece flush on the bolt in the alternator?
Thanks!!! Awesome video and soundtrack!
I have learned a lot watching your videos AFP, changed my motor mounts and look forward to doing my valve cover gasket and Cat converter on my 09 Altima soon! You're the best!!
My car has been losing power up hills. I'll be doing this job in a few days. Should I change the air fuel ratio sensor at the same time? Or should I just clean it? I can't find the genuine sensor, but so far, it's about $110 for the Denso brand. Thoughts?
Thanks for the feedback, definitely something worth considering. I have one more question for you. My a/c fan motor under the dash board is making alot of noise, probably full of debris 07 Nissan Sentra S. Could you give me ball park figure on just labor to change out fan motor for a new one? Being trying to call my local nissan dealership but it's practically impossible for someone to pick up the phone now days. Thanks for your feedback and video. Keep'm coming.
I think this was done at the dealership, guy had nissan ski cap on. Dealership are expensive out of pocket money if you don't have a warranty of some kind on your car. I called midas and a job like this was 1200 bucks and change. Thanks for video though, alot of work is involved.
My screws are a little loose.causing that rattling noise.how do I get to those without taking off the whole thing
