[@SMAutoRepairLLC]

You got this!

[@charlesfinnegan7930]

How easy was it to remove the bolts at the manifold flange? Did you have to cut the bolts and use new ones?

[@tigertoilet2]

Saws all worked good .

I need to replace my 2006 dodge grand caravan 3.8L catalytic converter and o2 sensor. What bank is the catalytic converter?

[@SMAutoRepairLLC]

So for 3.3 and 3.8 engines only 1 catalytic converter for both banks, firewall side of engine converter is bolted to the exhaust manifold accessible under the vehicle.

I am disappointed, I bought recently 2011 Chrysler Town and country and I felt The motor sounds muffled and the car's torque is weak, recently I got engine check sign , I went to O'Reilly and they told me from the code i need a new catalytic converter, i called the Chrysler dealer , they told me my car had 2 catalytic and each one price 2310$ + labor 295$ + 200$ for something I didn't understand what's that + tax , it will cost around 3100 for each , 6200$ for both catalytic

I have a 2009 volkswagen routan se it has the same engine i am having issues with bank 1 it says that it is the 02 sensor i have replaced both sensors but the flange with the four screws connecting the exhaust and catalytic converter was broken i had tried to use tiger patch to get a hold of the leak in that area however it is still saying that the 02 sensor is having problems in bank 1 would this indicate the need to replace the catalytic converter i have been thinking of replacing the entire exhaust but i am not a very skilled mechanic and dont have many of the tools you used to weld etc. should i attempt to replace the exhaust and convertor ? Maybe with a scrap yard exhaust im assuming this will fix my issue but im curious to hear some thoughts employees at autozone have not been much help

[@SMAutoRepairLLC]

So what is the exact code that is being set? I can tell you this for sure if you have an exhaust leak anywhere before the upstream 02 sensors all the way to the downstream it will most definitely set 02 codes.

[@8000ismymiddlename]

the current code is po171 The leak is right in the middle of the two sensors the sensor that comes right off of the exhaust manifold with the bolts in it connecting to the exhaust running toward the catalytic converter is cracked and fully disconnected i tried latching that worked for about one ride and went right back to sounding like a diesel or a hellcat or something just loud and poppy loses power even when I’m pressing on the gas i just replaced those two sensors and the egr valve to find that pipe is busted and i just bought this vehicle

[@SMAutoRepairLLC]

@@8000ismymiddlename yes so your on the right track for sure, have you tried to get with a local exhaust shop to see if any on it can be patched. The way it sounds look like replacing the exhaust is going to be your best option. If you choose to go used do a good visual inspection for any cracks or potential leaks before installing.

[@8000ismymiddlename]

I am located in the middle of nowhere arkansas haha so i have made some calls to try and figure it out and was told by a few guys that i should order the part myself cause its real cheap on ebay etc. than have somebody come weld her on for me cause i cant weld but hey man thanks for your advice i appreciate you taking your time to help me

[@SMAutoRepairLLC]

@@8000ismymiddlename no problem at all! Good luck

I have a dodge grand caravan 2005. Can i remove my catalytic converter without using any saw? I am willing to remove it completely and buy a new unit.

[@jjonnyboi1]

No

[@neidraduncan3869]

Which catalytic converter was it? I was told that there are 2 different ones.

[@SMAutoRepairLLC]

This vehicle only has one for both banks not
Your typical design. Exhaust manifold for bank 1 and bank 2 are bolted together, bolted at the firewall side is the catalytic converter accessible from under the vehicle.

[@neidraduncan3869]

@@SMAutoRepairLLC Thanks for replying so quickly. I was referring to two different models or types of converters. I was told there is California catalytic converter and a universal. Of course one being more expensive than the other. If you have a model/part number, I would appreciate it if your share this information.

[@SMAutoRepairLLC]

@@neidraduncan3869 No problem sorry about that. I could find you a part number both ways but you are correct there are federal emissions converters and California emissions converters, California being the more expensive usually. Depending on where you live is the difference between which converter you will need for emission standards. If you are somewhere like Kentucky where we have no regular or yearly emissions testing required or higher enforced regulations (California Equipped), federal emissions converters are the way to go but either could be used.

how many hours labor to install catalytic converter on a 2013 grand caravan with a 3.6L engine

[@SMAutoRepairLLC]

2.4-3.5

[@jloluv420]

the honeycomb inside might have been intact, could have been cleaned? curious.

[@SMAutoRepairLLC]

Absolutely, If There Isn’t An Issue With The Vehicle Running Rich, Burning Oil, Misfires Or Low Power From A Restricted Converter Cleaning Could Be An Option.Especially In A DIYer Situation. As Far As A Solution With A Much Higher Success Rate, And Not Having This Issue Reoccur, Replacing The Converter Is More Ideal For The Repair.

And us welders all wanna see how your welding skills are

[@SMAutoRepairLLC]

Right lol

[@YoJoeFRtho]

Can I use a stick welder on this pipe? I have a little suitcase miller welder

[@SMAutoRepairLLC]

@@YoJoeFRtho I would say mig welding is the best method for welding exhaust pipe, now with that being said it could be welded with a stick welder get your amperage dialed in. I would do a couple test runs using 1/16 and 1/8 stick to see what works best for you.
