2012 XK - rear exhaust box heat shield adrift...
Discussion
Hi.
Noticed this weekend that the flimsy aluminum 'tin tray' type heat shield above the back box has come adrift and is simply sitting loose on top of the back box. And rattling obviously.
The 4 bolts are still in place and the tray has simply failed around the bolts and fallen through them. This means that the holes in the tin tray are now bolt sized.
Rather than buying a new shield (that will probably fail just the same and cost me a packet to buy and get fitted) it feels like the easiest solution will be to re fix mine with some large washers - but not sure how easy it will be to get to the the front two bolts ?
Has anyone on here experinced the same issue ?
Thanks

Same on my 2008 XKR except my heatshield had parted company from the rest of the car entirely. The absence of the heatshield was noted at a service and inspection by main dealer. I left it that way for about 18 months until I swapped the back box for an aftermarket once, decided I might as well fit a heatshield while I had the back box off.
The bolts were all still there although I'd bought some new nyloc ones so I used those instead. I also bought some big repair washers and some nylon washers to go over each stud. It was still there last time I checked.

2010 XKR - but probably common to may later models - you can get to all of the bolts, you don't need to drop the box, the heat-shield comes out and goes in with some 'fiddling'. I worked from the nearside on jack plus axle stand.
I was tempted to just fit larger washers but reminded myself that skimping on an £80,000 car for a measly £25 would put me firmly in the cheapskate category, so I fitted a new one. When I got the old one off I realised that it had become quite brittle and friable and the larger washers would likely only work for a limited time before going through them as well so in the end I felt quite justified as I don't want to do that again.
Note - plenty of WD40 and soak time before removal if you don't want to break studs or just have the whole stud rotate when you try to remove the nut. Also, it clearly gets quite hot so I'm not really sure copper grease really has any benefit but I always admire an optimist.
