In this video I will be replacing the front and rear CATALYTIC CONVERTERS on a 2006 TOYOTA SIENNA LE. So if this video helps you please LIKE COMMENT and SUBSCRIBE TO THE CHANNEL.
Great job! I love seeing actual people doing the job in the real world rather than the tons of videos that are taken in a shop on a lift with all the perfect tools and everything just comes apart like magic. I know when I do stuff, I always hit an unexpected broken or frozen bolt and I usually wind up needing additional parts!
Thanks for this, I'm doing the entire system on my daughter's sienna today from the cylinder heads to the tailpipe, and I just wanted to see how the new manifold gasket goes on. There's no way I could afford to have a mechanic do it. Great job, much appreciated!
I have the same van and same color and year. I have to replace the y pipe and everything back including the muffler. Thank you for this. It will help with part of my job. You are very entertaining to watch
Thank you for taking the guess work out of the job. My Daughter took her Van to the local mechanic, they wanted 3k to do the job. I stepped in and said hell no ! Purchased 2 new cat's and 4 sensors for $ 250 from Ebay.
I like watching you do this job with the car jacked up, but not on a lift, and using mostly regular hand tools. That pipe you were trying to cut sure looked like it had be cut and rewelded several times. Those for sure were not factory welds.
No luck at all the aftermarket suck my check engine light came back on a month later and I didnt have to replace my O2 sensors they were working properly
Great video! I’m just wondering if you could tell me how you were able to get to the bolts on the cat that was at the back of the motor? When im under the car trying to access them, I can manage to get to the top three bolts that connect the headers to the motor, but the bottom three seem near impossible to get to? Any advise you would much appreciate!
I would recommend going over the top of the subframe in the back with a couple of extensions but you might not be able to do that until you remove the rear catalytic converter first I hope this help.
Im looking at buying the same cat converter on ebay; I appreciate you making this video- I was worried about breaking bolts off in the manifold, so i was gonna pay a mech to do this but I think I may be able to handle it- How hard was it to access the nuts on the back side manifold? I am a big guy not sure my hands are gonna get a good grip on a ratchet
I'm glad my video was a help to you. My hands are small so it wasn't hard for me. But I would recommend going over the top of the subframe in the back with a couple of extensions but you might not be able to do that until you remove the rear catalytic converter first I hope this help.
@@fixitchicktv Ty for your reply! I still have the bolts in place, so I should just be able to unbolt it without cutting- my sienna van has 300k miles on it and im having lots of issues with it right now- I am getting codes p420 p430 and I've replaced all the o2 sensors. recently my power steering pump/belt has been acting up (mostly in rain/cold weather) but I am not sure if thats causing the van to be really sluggish on acceleration and intermittently I feel a vibration and a low roar/hum that seems like it goes away when I give it more gas. My MPG has been terrible lately too, I think I am only getting 10-15mpg so I suspect that the cat is the cause, but there could be multiple issues. Exhaust sounds terrible, tomorrow I am gonna replace the power steering belt and inspect the front end/exhaust further to see if there is something else that could be causing my issues, but I really think its a clogged cat converter considering the mileage.
@@jeffandhisdogs Toyota p0420 & p0430: Catalyst System Efficiency Below Threshold (Bank 1 & Bank 2) Possible causes for the codes are A failed Catalytic Converter, A Faulty Oxygen Sensor, Damaged wiring and loose connection, Exhaust leak. I would recommend you check all the wires for the o2 sensors and check for an exhaust leak because I had a leak in my exhaust at first after I fixed that the code came back then that's when I replaced both of the converters then my check engine light finally stop coming on after I had erased the codes. I was wondering do you have the dust shield in place on the wheel well because if water is getting in it can cause the belt to slip so I hope this help you.
Check engine light was on. So I scanned for codes and got P0420, and I also had an exhaust leak as well, causing me not to pass the state required emission test. Thank you for watching my video
Well my check engine light was on and I was getting a code P0420 after I replaced the cats I erased the code and I was able to pass the emission test that is required in the state of georgia
