Evening All,
It's been a while before I visited the forum, but again I am in need of some help.
I've been hearing some nice big "clonks" from the back of the car when driving, and especially when going over bumps. Had a look under the car and there's an exhaust heat shield, located pretty much under the rear seats that's come completely loose on the driver's side. The holes where the bolts go through have completely worn out and they're now way too large to be help up.
This looks like a reasonable DIY job, but I can't seem to see the right part on the interwebs. Would anybody be able to point me in the right direction? The car is a 2007 2.2 Diesel without a DPF. It's a bit too dark to take pictures now, however I can try and do so in the morning if required.
Also, what's the risk of removing this part in the short term whilst I wait for a replacement, or am I better off keeping the car off the road until I've replaced it?
Cheers,
Jon

You could probably take it off completely but would some large penny washers cover the holes so that you can screw it back?
That worked for me.
EDIT
Beware that the threads will likely be rusted so clean them up and go easy getting the nuts off/on or the studs will break off.

They'd have to be some REALLY large washers, but I'll take a look. The holes have worn so much I'd like to look to replace it.

I have no doubt the purists will kill me for this but when a similar thing happened with my 2004 RAV4, I 'repurposed' some baked bean tins to make some plates and riveted them in place  |

Cheers, Jon I had the same problem on my 2008 XT5. It would appear that the "wear" is really corrosion caused by using steel fixings ( - i.e. the studs, washers and nuts ) for mounting the aluminium plate. Itis very difficult to avoid this corrosion, particularly in such an exposed situation and where it is too hot to use plastic or rubber isolation washers. My solution was to make some large repair washers from 16g aluminium and remount the heatshield with one on either side of the heatshield at each fixing - so you need 8 washers in all. This moves the corrosion area from the heatshield itself to the washers and, as they are much thicker than the heatshield, they should last a lot longer than the original fixings. I did mine about 3 years ago and have had no problem ever since. There is no need to cut the washers round, mine are about 50mm square.
