I noticed that the heat shield above the mufflers is messed up. The following photos were taken with me standing under the car (I'm very short!) facing the rear of the car. The first photo shows the shield on the right, it looks like someone took aluminum foil and stuck it in there, or is that part of the shield? The second photo is the one on the left, it looks normal.

Question -- is it hard to replace? I noticed that it goes way up under the vehicle.

Another Question -- is this something to worry about or should I just leave it? Seems to me to be something that I should fix.

 

I just went out to the garage to look at mine (I'm very tall but have a lift), and it looks like you may have to take a lot of the car apart to replace it. But, being in Florida you may find your carpet getting very hot if you don't do something. Maybe you can find a way to attach some pieces of junk yard shields, as the Jag parts probably cost a fortune.

 

I fitted 2 new ones to my bodyshell, one was easy to get, the other took a while on back order, the one over the gearbox in the picture was later swapped for new. Jaguar have them in stock I think.

By the look, it's the front one that needs replacing, and that should be easier than the rear one. You can bend them a bit to install over the prop after the trans and slide up to position.
Part number for front GNC9330AB goes over the trans, the rear GNC9341AD.
I think they were about Ł100 each.

 

I got confused, thought I was on XK8 forum. There is a big difference in mounting location.

 

I didn't post such great photos, but I'm pretty sure I need #4 in this illustration.

 

Hi OldMike
Here is a JPEG file of the XJ X308 exhaust system components. I added the part names to each of the components in the diagram.

I thought that this might help identify the location of the heat shield that you need to replace.

When the dropbox webpage opens click on the image and increase browser zoom to 125% to get a sharper view:

Thanks Jim. I'll have to get under the car again and see exactly what's up.

 

BTW I have JTIS installed on my iMac but I have one heck of time finding anything. I thought for sure I could find the illustration showing the heat shield and instructions on removal and installation, but nooooooo! LOL

 

Hi
I think you are right about the heatshield (over axle heatshield) figure #4 on diagram.
I had a look at our intermediate muffler by putting my head under our 2001 XJ8 right before these rear axle.

It has a heat shield there that goes under the 2 intermediate muffler and above the rear axle.

Here is anonther JPEG showing the heat shield and the over the axle heatshield that I created:

I have started to use the parts lookup on the website that Sean B has pointed out in other threads. Its has the browser zoom feature advantage over the JEPC software. Now I am able to increase the size of the diagrams and text with only minor distortion.

Part no. GNC9341AD | Over axle heatshield Parts From Jaguar Classic Parts UK

The JTIS shop repair software does not have r&r procedures for every part on the vehicle models that it covers. The muffler heatshields and some of the heating system hoses r&r are some of the procedures not included.

Also there are some reference procedures called out with SRO numbers that do not exist in the software (these are called software bugs - errors), but most of these can be found under another SRO (Service Repair Operation) or procedure related name.

Your best bet is to try to locate the heatshield by calling your local used parts recycler.
The part number is GNC9341AD - Gaudin Jaguar list price is $130.50 less discount plus shipping is $120.97. Jaguar of Greenville total price is probably about $10 less (they give a 15% discount and free shipping on orders $25 and over to Jaguar Forum members).

I called our local recycler - Tom's Foreign Parts.com and they will be calling me back - they have 2 xj8 in the yard to see if the part available.

Thanks for all your help, Jim. Your second link is from the same place that I got the parts diagram that I posted above. My issue at this point is not so much how much the part costs or where to get it, but more how hard would it be to replace. I've decided that unless I can find a local parts yard that I can go to and see the piece before buying it, I might as well play it safe and get a new one and just spend the $$$$.

So, at this point I'm wondering if replacing it would be a royal pain or something that is doable in the garage or something that I should have my mechanic do for me. As of right now, I'm not able to determine the removal procedure.

 

I have a Alldata DIY subscription for our 2001 XJ8 - Std Shop Time for intermediate muffler R&R is 0.5 hrs for each side. Procedures in JTIS is SRO 30.10.15 (LH Vehicle USA) and 30.10.16 (RH Vehicle Rest of World) use SRO search.

Drive/Propeller Shaft Rear Axle R&R - Std Shop Time is 1.9 hrs. If it needs to be removed, then maybe only front or rear coupling need to be taken down to get at the heat shield???? --- probably 1.0 hrs ???? in any case there is important caution - see Procedure in JTIS - SRO 47.15.01 Driveshaft (use SRO search).

Maybe you can send PM to Sean B, Motorcarman, Brutal to get their expert advice?

Thanks Jim, sounds like maybe it's more work than necessary. I was hoping it would be much easier -- maybe just loosening or removing part of the exhaust system and leaving the drive shaft alone. My other option would be to find a used heat shield and try to attach the "wing" to where it's missing on my car. Just a thought. Not sure how I'd attach it, so maybe that's not even an option, but if I could, it would be so much easier than replacing the entire thing.

I don't like the way it is, I want to do something.
