    Good/bad idea?

    The bolts and studs have rusted away to nothing so its sitting on top of the back box rattling. Cant get in touch with my normal garage. (think they’ve closed down)

    But what glue? was looking at some Sticks Like Sh*t

    last time that happened to me I removed it altogether and it made no difference*

    Something like this maybe?

    Indeed – do you need it?

    What car is it?
    I had it happen on a heavily modified fiesta, standard heat shield over the back box on a £700 exhaust system.

    I took it to the tuning shop that did most of the work for me, and the owner just ragged it off completely and said ‘problem solved’.

    Never caused any issues.

    Also any excuse to post some exhaust porn.. Can you guess which one was the standard exhaust?

    I miss that car!

    The garage took mine off on my old jettex SS exhaust. Told me not to park on long grass…

    It’s an Alfa Mito QV, I know I could probably get away without it but would rather get it on properly with new studs. but doesn’t look like its happening if i cant get it in the garage i trust.
    also cant even slide it off and deal with it some other time wont get over the box

    The one with the catalytic converter. You child killing, baby robin poisoning monster! 😉

    You want to glue it to the car? Something silicone would be my advice due to the warmth. https://www.everbuild.co.uk/product/heat-resistant-silicone/

    Something I have used before called Stixall. I used to it to glue radiators to the walls of flat after it was tanked! But only rated to 100 degc

    On my car, the heat shield itself perished where it was bolted, so I undid the bolt, fitted a large washer, and bolted it back up. Is there anywhere it can be cable tied to ?

    I think I shuffled under my car and stuck one back on with some zip ties and bit of old gear mech cable.

    There’s nothing to tie to, a crumbly bit of bolt left, i tried holding it on with some copper wire wound round but was a losing battle.

    I did initially strap mine back up with some wire, but these heat shields are paper thin and mine just rotted further and it started rattling again after not very long.

    Starting to think I should put wire round it so its tied to the box, wouldn’t rattle and do the same job right?

    It’s Italian, it’s designed to fall off to save weight, our Panda exhaust sheds skin like a snake.

    They do very little, may as well just slide it out.

    See above, it will work as a temporary fix but if it’s already corroded it will just rattle lose again in not very long.

    I’ve ragged a few off the rear section of several exhausts. No fire to date…

    I used a webbing strap to keep mine on, it’s been fine for a year, and went through an MOT

    It was indeed silicone based adhesive.

    That’s possible I suppose but then why do they bother fitting them in the first place when they could save a bit of money in production by not bothering?

    The wire option has worked for me in the past, it’ll stop it rattling and won’t melt.
    Ripping the annoying heat shield off also works.

    Had a Friend who used cable ties when the exhaust mount broke on the back box. Needless to say it lasted about 3 miles and left nice smelly plastic goo on the back box 😆

    I used coffee cans, it’s plastic coated aluminium so gets around the galvanic rusting.

    I cut them up to make big washer type things so the bolt can hold the mesh again. Lasted another 80k miles before the thrust release bearings went in the gearbox/clutch writing it off.

    Like above, just rip it off, their entire purpose (in the UK at least) is to cause an annoying rattle after 10 years then mutilate your hands while you remove it. Oh and sometimes they make it really awkward to adjust the handbrake

    That way, next time it falls off everyone aboard will die

    Rip it off, toss it into a skip, enjoy life. 😀

    Had this happen to my car. It’s not bolted on but pushed onto studs, which look like rusted bolts but are fine. The fixing washers have rusted away and the heat shield has fallen past them. I pulled the old washers off (all but one which wouldn’t budge) treated the posts with some anti rust stuff. Bought some generic fixing washers from eBay and fixed it back on.

    You can get lengths of Jubilee clips which I’ve used. So long as you can get them all around the shield.

    What sbob said. Doesn’t feature on MOT so nothing to worry about.

    That’s exactly what it is, I thought it was rusted bolts! The heat shield is still in good condition with the old washers attached just with no grip.
    Had no idea press fit washers were a thing, ordered some from ebay, wouldn’t get it done this weekend anyway I’m not lying in the snow/slush to do it.
    Cheers.

    Was rattling on my old car so took it off and binned it (in the relevant recycling receptacle for heat shields obviously)
