Hi to all, this is my very first post in this forum.

I have serious problems with the catalytic converters of my X-Type (2.5 V6)
Which means they are not working properly anymore.

So, I would like to remove and replace them by myself.
According to Jaguar JTIS removing the front subframe is necessary for replacing the right hand cc.

Question: is there no other way of getting removed the right hand cc?

The search function did not get me any answers.

I have asked various people who should know, but they are either not able or not willing to explain how this can be done.
But, at least one of them said that "it is not such a tricky thing", so I would suppose there is an easier way without removing the front subframe.

I really hope you can help me.
Please excuse my English, I am from Italy.

 

welcome to the forums, i do not know how to remove or replace thr catalytic converter but why dont you take it to a muffler shop? the catalytic converter is the part that is going to cost you the most the labor shouldnt be that much since they are just welding it in. call a few muffler shops in the area for quotes. it might not be that much.

 

I agree with jaggyx. Exhaust work can be frustrating because the bolts are likely to be seized and you may need to cut them off. Also, you need a reasonable amount of room to get under the car and maneuver things about. Most exhaust/muffler shops aren't that expensive for the labor. It's the part that's going to rape the wallet.

 

Thanks for your replies.

I have already purchased the converters (used parts).

Unfortunately there are no muffler shops i could turn to in my area.
The only possibility would be the official Jaguar garage (there is only one).
But they are very expensive and have not a good reputation.
I am quite sure it would cost me nearly a 1000 dollars.

Other motor mechanics usually do not even touch Jaguar cars, as they are uncommon, so they have no experience with them.

So, I really would like to know if there is no other way than removing the subframe.
I think my skills are not that bad, but I definitely don't have the equipment to remove the subframe.

 

The Jaguar World magazine covered the removal of the X Type AWD transmission over three issues: Nov, Dec 2008 & Jan 2009. It does look like the subframe has to be removed to get at the rear cat. It looks like a very time consuming and difficult job, but not beyond an experienced diyer. I personally would attempt it if necessary, but not without a good deal of thought about how to tackle the job first - tools, help etc.

 

Jay, by "offical Jaguar gargage" do you mean a Jaguar dealer or an independent shop that works on Jaguars. If it IS a dealer you might have some more bad news in that they might not want to install a used part, especially if you are not a regular customer and do not have a previous relationship with them. If that would be the case unless you could return the parts you already ordered you would be SOL.

 

You'll need to remove the transfer box to do the rear (RH) cat. Not for the novice. I would not recommend putting used catalytic converters on it....they are labor intensive to install, and if they are junk, you be right back where you are now.

My $.02

 

The rear cat can be removed without removing the subframe. Personally I find the procedure frustrating and at most it will save about 45 minutes from the job. Worth it when you are working flat rate but probably not when you are on your back in the driveway.

 

Would it be possible to just cut out the rear cat, then just splice in an aftermarket cat for that bank farther down the line instead of using an OEM replacement?

I realize you'd probably have to do some wiring work with repositioning the 02 sensor, but is it feasible?

 

Anything is possible but the problem with the X-Type is that both cats are made of cast iron where they bolt directly to the exhaust manifold. You would have to fabricate a new flange to bolt to the manifold. I suppose the easiest way which wouldn't save any time would be to remove the cats and gut them so they are free flowing and then install aftermarket cats downstream of original position. Again a lot of work but possibly cheaper than factory cats and would avoid fabrication at the manifold flange.

 

Ah, yep but you are back to square one with having to remove the subframe or screw around and try to squeeze out the rear cat.

Wonder if you could remove the lower downpipe, gut the cat from below, then put the downpipe back on and then splice in the aftermarket cat. Just thinking out loud here.....

 

I think it's worth going to a muffler shop to get a quote / advice, they don't have to be jag specialists for that.

 

Good news for me.

Could you please give some more information about how this can be done?
Which parts do I have to remove?

 

i assume you are going to fit new cats.i dont know about elsewhere but here in england if the car was fitted with cats when new it must retain them otherwise it will not pass the vehicle test requirements,for this reason you may not be able to change their location either.also any lamda sensors or otherwise that are fitted to the system may be affected by location change.dont forget the exhaust system was designed for optimum operating range and will be affected by any changes.

 

So, now I have removed all bolts and nuts, but I don't find a way to pull out the (rear) cat.
Who knows where it will pass?

 

Finally I managed it to replace the rear catalyst.
It is possible without removing the subframe.
The exhaust manifold has to be removed, as well as the intake manifold.

The old converter was totally broken inside.

 

If your in the states the emission system is warrantied by the government since emissions equipment is required by the government. So check on that and it would be replaced free of charged at the dealership or local shop.

Granted if it became defective on its own and you didnt destroy it yourself.

 

I have the same problem they are bolted in no weldding is necessary but i have to figure out a way to replace them the dealer quoted me $ 2,785 with labor and parts

 

Jay1980, what were your symptoms that led you to replace that cat, and did the valve covers or A/C lines need to be removed as well to remove that rear cat?
