Albert27 Posted February 23, 2017 Share Posted February 23, 2017 Afternoon all. In the strong winds today a piece of metal has come loose and was hanging down near exhaust at rear. Probs already loose but the wind seriously dislodged it further so I pulled it out. There was nothing holding it in. Pictures to follow.. My questions. What is it? Is it important? How do I replace/fix it? Thanks in advance. 1 Quote Link to comment Share on other sites More sharing options...
dezwez Posted February 23, 2017 Share Posted February 23, 2017 its part of the heat shield you can put it back on with over size washers and nuts not hard to do 2 Quote Link to comment Share on other sites More sharing options...

If the bolts i saw up in the space are for it - and looking at the size of the holes, maybe it's just rusted away. In that case, would i need a new one? If not, Can you give me a a link to the type of washers/nuts you mean? Cheers mate! 1 Quote Link to comment Share on other sites More sharing options...
dezwez Posted February 23, 2017 Share Posted February 23, 2017 it protects the rear floor from the heat of the exhaust no need to renew it just put bigger washer than the holes in it http://www.ebay.co.uk/itm/A2-Stainless-Steel-Penny-Repair-Mudguard-Big-Washers-ALL-SIZES-IN-STOCK-/332058482169?var=541091113396&hash=item4d503a55f9:m:m54P3EUQiGTEUPWr6_4CZ1wand re fix it 2 Quote Link to comment Share on other sites More sharing options...

isetta Posted February 23, 2017 Share Posted February 23, 2017 similar heatshield fell off on my wife's mazda2, same thing happened, it corroded away where the bolts washers were holding it on, hence the big holes. as said above it can be refitted using bigger washers (washers which are bigger then the holes in it). i did not bother refitting it on the mazda2. it seemed just to stop the heat getting to the boot floor. i suppose in theory the heat might shorten the life of the spare tyre by a microscopic percentage or make your frozen food shopping defrost. old cars did not have these. it might be worth checking you don't have any pipes / hoses for brakes / petrol very close by. 1 Quote Link to comment Share on other sites More sharing options...
Jonanstee Posted February 24, 2017 Share Posted February 24, 2017 I've had all my heat shilds off for a good 6 months or so now. No problems at all so you will be fine leaving it off :) 1 Quote Link to comment Share on other sites More sharing options...

This could be a long steep hill climb at close to full throttle in 35 to 40 C ambients, then a stop at the top. You will have a really hot exhaust system right to the tailpipe radiating and convecting considerable heat affecting nearby components. Since you and I are unlikely to do this in the near future I would not rush to refit it. ScaniaPBman. Quote Link to comment Share on other sites More sharing options...
stef123 Posted February 25, 2017 Share Posted February 25, 2017 Do a regen on a car with a dpf and no heat shields and let us know how long it takes the carpets to start smoking lol 3 Quote Link to comment Share on other sites More sharing options...
Commencal24 Posted March 5, 2017 Share Posted March 5, 2017 I had to go under my mk2 yesterday and noticed a very loose heatsheild, and a corroded exhaust bracket to go with it 😩 I did start to notice a little knock coming from underneath on acceleration Friday...

Commencal24 Posted March 5, 2017 Share Posted March 5, 2017 Hope so, I had loads planned for today, made my template for the additional boot light, purchased led side lights to fit and I couldn't do any of it 😕 Quote Link to comment Share on other sites More sharing options...
Albert27 Posted March 18, 2017 Author Share Posted March 18, 2017 Update: Managed to get two of the jumbo washers on the car but the third heat shield bolt is rounded off. Have put some plus gas on it and will try the hammer and mole grips trick this afternoon. What size are they and where would i get a replacement one? It's like a nut and washer all in one..........

The jumbo washer moves a little but I think it will be enough to hold it in place! So heat shield is back in. Did you use standard mole grips? I've seen these and just wondered if they are superior for rounded nuts and be worth investing in....... https://www.amazon.co.uk/d/Spanners-Wrenches/Toolzone-18-STILSONS-PIPE-WRENCH/B001O5M1ZC Quote Link to comment Share on other sites More sharing options...

It's caused because the 'shield' is aluminium and the nuts are pressed steel so being under the car, road salt, chemical reaction (yadda yadda) causes them to corrode. Some people just cut washers out of an aluminium Coke can and buy new nuts to refit them but as others have already stated they can be safely removed and left off! Take the car to a garage and chances are they'll just rip the part off and ditch it like my local garage did on my fiesta mk6 when I had this happen.

So long as your heatsheild doesn't rattle about I think you'll be all good 👍🏼 1 Quote Link to comment Share on other sites More sharing options...
WallaceZS Posted March 20, 2017 Share Posted March 20, 2017 The same heat shield has been hanging down underneath my ZS for a year now, I've just not got around to fixing it. It was an advisory on the MOT, I'll let the garage fix it when it goes in for its service in a couple of weeks. I have seen some people just cut up a Coke can, layer it and use that as an oversized washer. Quote Link to comment Share on other sites More sharing options...
stef123 Posted March 20, 2017 Share Posted March 20, 2017 An oversize washer of tigerseal is what I use depending on the situation. 1 Quote Link to comment Share on other sites More sharing options...
