How to clean catalytic converter while on car, customers request to spray down with cleaner 

Thank u yup I tried to help as much as I can I do get comments that’s I can’t reply back some times it shows but when I click it dosent come up

Super Glue LOL!!

Nice good job!!!

Just wondering if I have to remove the bottom sensor as well? I already popped off the top one and I have the throttle body cleaner but I don't want to spray it in there and have it catch fire. Do I have to remove the downstream one as well or only put it in the top and clear out the the honeycomb? I inspected it with a flashlight in the Combs look perfectly fine

​@@krakenhits1587did you ever figure out if the down steam sensor needs removed too?

@@BRANDONGONE92 no

The answer to your question is said in the video, but it isnot shown. He said to make sure you do the bottom one.​@krakenhits1587

Nice great job!

Nice good job

was gonna say the same thing would have taken 20 sec

no its must be cleaned with cata this is wrong cleaneng...

Ohhhh man I wish u would have used the camara to see if their in immediate reaction.

True

You basically want anything that’s going to eat carbon diesel fuel, purple power, optimizer GM top in cleaner, the foam spray and you really want to use a whole can on it and just let it set that GM Pop in Cleaner if you spray the cylinder or a cat and let it sit overnight And then the following day get the cleaner out look at it with a borescope camera. He looks brand new in there the GM top in cleaner optimizer for Chryslers that is for carbon cleans. It breaks the carbon down into dust you could D carbon your motor with water it’s a old-school trick, I’m not going to explain it how it’s done or watt temperatures or anything of the sort because if you’ve never done it, you can destroy a motor it’s the old-school trick and the old guys out there know what I’m talking about they’ll know exactly carbon and water. Don’t get along with each other who loses the battle the carbon does, this is how they done it before we had all these chemicals all old-school tracks there’s still out there we still use them. They work on modern days now computerized a lot of times you still have to use them. There’s guys out there that knows the tricks and lotta guys don’t like to give their tricks up they don’t believe in letting their information out And I’m one of them because if somebody does something wrong I’m liable I could be sued because they’ve done it wrong. The way the world is now everybody wants to sue and there’s one say payday is what they say not on my clock. I’ve told a lot of these guys it put a RU-vid videos out. You got a watch it because you put that information out and somebody does it wrong you’re liable That’s why I don’t put a Videos out because there’s too many people out there that don’t use common sense no more that’s the number one reason they can’t think on her own and the new generation out there is coming in the automotive they think the scanner is the god that code is the problem. The thing is they need to learn how to read the scanner read the data That scanner disappoint you in a direction. Where are the problems that and then you got a figure it out you have to diagnose it because the scanner will tell you if it’s electrical problem mechanical problem, sensor problem or internal problem it’s all in the way it’s worded, you have to know how to read between the lines And have enough background in the automotive to figure it out or diagnose it and a lot of guys out there. Just want to throw parts at him all day long and just say check engine light used to thousand dollars worth of parts at it still not fixed it could be a loose pin. It could be a bad ground. It could be a broken wire, or it could be were a mouse chewed on the wires why do you have to get a meter out and start diagnosing it nowadays that is a bad word to people they don’t want to hear diagnose in a vehicle. They just want to throw parts at it and go people need to learn how to take a step back idle down take some time fix it, right Yeah there’s some vehicles were you have to have a part known good part for a test part for a quick test to determine OK which is it here? If you’re in a time frame you can throw that part on there OK spit out another code OK that wire is good but it’s not. It helps you that’s all I’m a say and then you just have to figure it out yourself. and people need to learn how to pronounce catalyst system not Cadillac.

Good job!!

No concern for UT catching fire?!

Still no check engine light?

Update please.

Yup welcome!!

Good luck!

Nice good job

For how long did it worked?? Am trying to do the same thing to mine but I was wondering if the check engine light stay off

@@elmexicanodelabarba3245 give it a shot maybe it lasts longer than you think America mechanic will charge 2000K for replacement 😁 awful service

Yup

U have to let it dry for couple of hours

@@RBTheMechanic ok

Are you referring to soft porn? 😂😂

What kind of coupler did you add and where? I'm having the same issue.

Good job!!!

Is the code came back?

@@marsinbako8491 most cars I do don’t and it dose improve fuel economy also clean out the oxygen sensors

@@marsinbako8491 Yes it did. I looked through the 0- sensor hole with a camera.Catalyst material is not broken or stopped up. I installed a extension on the # 0-2 sensor and reset the p-0420 alarm.Problem has not returned in 2 months.There is no emissions testing in my state.As long as they don’t, I am going to treat it like a low tire pressure alarm.Not interested

@@jamesdavis8021 what was the extension you purchased. Do you have a part number

Oh wow u did lottttt I think maybe cleaning the maf sensor did the fix!!!

No problem!

Yup

Oh those are terrible!!! Try fixing ur oil consumption issue first

Check out piston soak videos.. B12 cleaner or others

Good job!! Merry Christmas!!!

Have you waited for couple of hours ?

He didn't use mass air flow sensor cleaner he used throttle body cleaner he clearly showed you the label, there is a difference!

So I need you to make me a small video showing me where the o2 sensor is lol on a 2011 Nissan Sentra lol jk I will google it or U-Tube it too !! But THANK YOU SO VERY MUCH FOR THIS INFORMATION BECAUSE I DID NOT KNOW IT

😂😂😂

Thank u

​@@RBTheMechanic umostwc

Yes

Yup use catalytic cleaner let it dry off for a bit also u can try fuel injection

@@RBTheMechanic Thanks so much

Do you mean to say that, "..you can use fuel injector CLEANER"?@@RBTheMechanic

Cool yup let me know

report please, report. it's 6 days ago. What happened?

@@irisbaez1972 I’m sorry refresh my memory

@@RBTheMechanic John leigh says he will report back, still waiting but he never came back

@@irisbaez1972 oh yeah true lol I though u was waiting on somthing from my end

Welcome!!!

​@@RBTheMechanicdid it work ?

Yeah but that would make job hell of difficult pressure would go out valves

This been good ever since. Passed inspection and all

Ok

Seafoam didn’t work for me.

@@lorikuck19 You're not supposed to ingest it.

@@MexicoAdventurer no shit. 🤦‍♂️

​@@lorikuck19didn't work as a laxative either?😂😂

Nice job!!!

Did it come back?

@@originalimmigration Not yet but it was only yesterday and I have only driven 25 miles.

Came back?

@@Jerri001 No not yet! It has been at least 2K miles if not 3K. Still no engine light!

@@theMatrixEndsHere thanks

Nice good job

Yeah

It worked well for me

Yeah If you want to fu*k up your engine insert lacquer thinner. How stupid do you have to be??

Oh niceee

which injector cleaner?

@@nadeem5476 crc

@@nadeem5476 Israrted with cataclean twice it went away for 100 miles. But it came back for another round. I tried B12 chemtool same thing. I tried high octane more power but same issue. I tried Lucas, gumout, stp, and I can't remember what else. I found out that a regular stp or gumout used on every full tank will keep the code away for longer. Some how now I have to use it for ever. But like I said this is a 230k mile engine. I can't say what for newer

@@fernesal try using laquer thinner a gallon In half a take drive till the half tank is gone

If you use a fireplace poker on your cat, the SPCA (Society for Prevention of Cruelty to Animals) will want a word with you!

So would I

Oxygen sensor socket 22mm or 3/8

7\8 special slit socket

Well I would reset and wait for the light to pop up and scan again immediately

It shoots as much as it got in the barrel for the moment

Lol

You're welcome!

Is the p0420 code still off?

@@ducrogers302 yup car passed inspection also

No best thing u can use in this can is fuel injection it will enter from engine injectors and go through whole systm

Ok

Thanks

If u becarefull u should be good but do so

That’s what I thought 😂

Wow I have 99 Toyota Camry manual transmission and the code came up as a catalytic converter, I didn't think to try the process of elimination and clean the O2 sensor but I will try this. Hopefully it will work.

What’s the issue with twisting the wires? You know that how manufacturers store the wire and how do you think it looks inside the wire loom? If you are worried about the wires breaking then it’s probably time to replace the sensor anyways

A lot of Toyota connectors become brittle over time. The huge pain in the ass of hunting another OEM connector down alone makes unplug as few things as possible.

Yes it could be bad catalytic also down stream sensors

Font see why not🤷‍♂️

The EGR valve gets build up on it too. It can be cleaned as well. The intake manifold too. ( Dodge caravan 2.4) I'm referring to.clean the " tube" that goes to and from intake manifold too. On my van ( caravan) that " tube" was clogged up . I bought it from a one owner

But there’s no misfire or oil in spark plug tubes

@@RBTheMechanic That's was one of the issue of the 2005 RAV4 I was working on (although minor) Valve cover gasket is next on my list with PCV valve to manifold hose disconnected at manifold (customer is on tight budget!) Code P0171 fix on it ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uS3IcsBIAAE.html

@@mkrp4 yup could be the issue good information to be away tho I see people drive around with heavy misfire and they lack to repair the issue then it gets more costly

You are correct. Quite often that is the case with DOHC engines.

@@RBTheMechanic That’s what my reply is always. People saying coolant leak into cylinders BUT coolant level is the same & oil looks great

Into the cat? By removing it? Why not in The gas tank as a first attempt? I am Dreading taking the cat off I want to try adding it to the gas but…..But I’m scared. I have a 2005 Toyota matrix with 303,000 mile on it.

Almost 300,000 mi on toyota prius 2006. No worries, 1 gallon laquer thinner to 1/2 tank gas. is ok. I did it. Works. But you still mat need to replace 02 sensor.@@chlatepdng

22mm oxygen sensor tools

Yupp I use crc lot

@@RBTheMechanic I don't care what they say You're a beast!

@@BlimpChimps yeah bro!!! Every single viewer got to save money!!! Solid Guillermo clean videos easy to do urself

can carburetor cleaner work as well???

@@victorjegede4380 yuppp

Only from my trusted part store “ Buywise”

U have it ready then spray

Check vaccum leaks and injectors

Yes u can do either or it’s fine

I u can clean sensor but after u do this or replace sensor the down stream

Yupp also clean out rear o2 sensor

@@RBTheMechanic ty compa👍

Yes I had free I had to clean or replace the downstream o2 sensor check that also

Nooo u turn it straight capture the fluid spray then repeat unless u wanna try to go down in straight angle

Try catalytic cleaner or fuel additives

Yeah that’s good idea also

22mm

Yup

U can do that as well

Welcome

Yeah lol I done that with throttle into intake

I thought the same thing

Oh ok yeah smoke will go away

U can try fuel edditeves before replacing it might get cleaned out or u can try replacing down stream sensor other wise u need to replace the catalytic

What did you end up doing? And did it fix the p0420

@@ducrogers302 had to ultimately change the catalytic converter

Not Fron down stream it has to be from upstream

@@RBTheMechanic would this spray be safe to use to clean the carbon out of the EGR exhaust port/channel?

@@apollo11capcom39 yup

Turn it straight it adds pressure

Scan the car for codes even if u have no light and see if there’s any pending or memory codes with high end scan tool

Yup. One before and after

I have used seafoam

Try cleaning oxygen sensor also if it don’t work out try changing oxygen sensor first before spending money on catalytic

So how did it go?

@@marsinbako8491 no, no, these people comment and then disappear.

Nope been good every since

No need

Antizseize should be applied

No replace the sensor don’t mess with catalytic

Yes u can dosent matter hot or cold

Drill hole? U don’t do that access through o2 port

If it severely restricted then u have to replace it

Do u have codes for catalytic. U can remove the oxygen sensor before the catalytic it will be loud but u can confirm it this way

Bolt will brake !! I rather take out the sensor

Yes both would be good cold and let it rest over night or few hours

Also another question, do I use half the can or the full can of spray cleaner?

@@orinyellowhair8278 less than half

Yeah just make sure u let it dry

@@RBTheMechanic thank you

No not with car running never do that

@@RBTheMechanic ok so i have two sensors one in the back of the turbocharger and one is after the catalytic converter do i spray inside both locations of o2 sensors or just the one that is close to the catalytic converter

@@ahkh642 what kinda car u have not sure the set up of ur catalytic but it might not work out due to location on sensor

@@RBTheMechanic you probably have never heard of it , it's from a Chinese manufacturer called Gac Motor , Ga4 . anyways thanks for your help i really appreciate the dedication you have for your channel you're a really nice guy i hope you get whatever you want in life you sure deserve it

No try cleaning g or replacing oxygen sensor first downstream

It needs to be driver not all cars get ready in 200 miles some before some after usully cycle is 90 miles so try 90 miles then if u got scan tool to see if it’s ready or not other wise u have to take the chance

Ok
