Heat Shield Needs Replacing

12 posts in this topic

Hi All,

 

The heat shield on my 111R has started to fall apart, behind this (rear n/s):

This is what it looks like from behind the rear wheel:

It looks like you can buy the sections here: http://www.deroure.com/diagrams.asp?TBL=5782&MAK=1&MDL=11&SMA=0&SMO=0&ST=&SC=0

 

Items 5, 6 and 31 I think.

 

However, they cost around 50quid each! Ouch! Does anyone have them spare, following an exhaust upgrade or something they would like to sell on?!

 

Also, how easy is it to replace? I can't see how you can get to it, maybe remove the rear wheel?

 

Thanks,

 

Baz

I doubt anyone will have it spare as it's retained in an exhaust swap. It bolts onto the u bend on the cat. You can just use manifold/exhaust wrap instead which will be a bit cheaper.

 

I used wrap and then put new nimbus over the top.

 

Make sure you do something as that section of pipe gets very hot and it Is pretty close to the rear tyre and other components.

 

5/10 difficulty to replace. Remove wheel, remove wheel arch liner, remove undertray. Then be prepared for some swearing as I seem to remember the lamda sensor needs to come out (need open ended spanner or special socket with slot for cable. Then the two bolts that hold the heat shield top and bottom will have rusted. You will also need a pop rivit gun the join the two new halves together.

Thanks Chris,

 

Any other places to purchase this stuff other than above?

 

Actually, can you recommend any exhaust wrap and places to get it?! That sounds like a cost effective solution!

 

Thanks again

You could ring one of the advertising dealers and see f they will do you a deal on the nimbus heat Shield. It will only be available from deroue or a lotus dealer preformed In the intricate shape. There is no way you could make the shape yourself.

 

Exhaust wrap from loads of online places like demon tweeks. If you use wrap you won't need to take sensor out.

Wet/soak the wrap first and wear some gloves would be my advice.

snap on my exige. i bought the best wrap i could and took my time ensuring all was well covered.

didn't replace the heat shield as it seemed to me that it would happen again.

Rich,

 

Did you remove the knackered heat shield prior to using the wrap or put the wrap over it?

 

I'm sorry if I'm asking a stupid question, I've never used wrap before, is it sticky flexible stuff or something?!

 

...and if you could remember what type of wrap it was, that would be a great help!

 

Thanks,

 

Baz

I have just replaced the heatshield on my S1 Exige. Having considered all options, I went with replacing for a new standard part. You pays your money...

Mine has also done the same - clearly a common issue. Fortunately mine was in position where I could extend the life a little bit as the main damage was the mounting holes on the lower section had pulled through, the forward hole on the upper section has also pulled through but the rearward mounting is still solid.

 

I would be interested if anyone manages to source new shields for a more reasonable price as when the time comes I'd prefer to fit parts in line with original specification.

 

In terms of fitting/replacing - to me it seemed getting the rear 'grill' panel out would make access significantly easier, but due to the lip at the top of the panel, and at the top of the heatshield rivetted to it, I couldn't get it out between the large exh silencer heatshield and rear clam - is there a trick to doing this?

hi

i removed / it removed itself when i fitted my tubular exhaust, corroded around the bolts as above and tatty round the edges.

exhaust wrap is like a mixture of 2" wide webbing fabric mixed with loft insulation and just as unpleasant to work with :)

wraps easily just ensure you cover all areas of the pipe , not a difficult job, otherwise i wouldn't of attempted :)

Well I finally got around to buying the heat shields and thought I’d have a go at removing the old one.

 

Managed to release the bottom tray with no trouble.

 

Also got one of the bolts out of the bottom section and although the bolt will require replacing (M6x10), I was quite happy and decided to spray the others with WD40 to free them up slightly.

 

Unfortunately, whilst trying to remove the second bolt from the bottom section the following night, the head snapped off!  L

 

I’ll post some pics later, but I’m a bit stumped to be honest, I could probably get away with attaching via just the 3 points.  However, I’m unsure whether I should even attempt to remove the top ones, ‘cos if it happens again, it’ll be a nightmare.

 

Any advice or help, if someone has better tools, would be great!

 

Thanks!

It will rattle if you don't put all the bolts back in, so you need to try and get them all out.

 

Run a drill slightly smaller than the bolt through the broken off bit, if your lucky this will remove it, if not then go up a size and re tap it.

      Is anyone running an S2 K-series elise with Hurricane/de-cat and either Larini Club Sport or EliseParts exhaust.
       
      I'm finally getting round to changing the standard set-up in exchange for pops and bangs now its no longer my daily drive.
       
      I'd love to hear the sound of both in the flesh or any comments from people who may have had something similar in the past.
       
      Cheers, Jim

      Has anyone done a comparison between an S2 k-series manifold and an aftermarket 421?
       
      I've got a 2bular 421 on my S1 111S which has given much improved torque over the standard item. The only downside is that I'm sure it's quite a bit noisier than before, but as it was fitted so long ago I can't remember what it was like! I think a lot of the change in sound is probably down to the change in material, from a cast item to tubular stainless. It may not be noisier, just more metallic, if that makes sense.
       
      I've been on a bit of a mission recently to try and reduce noise volumes in the car - it's an age thing I'm pretty sure! So far I've added carpet, put the std airbox back on and fitted a quieter silencer and it has made the car so much more enjoyable (for me) without really taking anything away. The next thing on my list to look at is the manifold.
       
      I've read a few posts over the years that suggest there are two potential improvements that could be made to an S1 on the exhaust side whilst staying pretty standard. The first is to grind out the clag in the standard S1 manifold, the second is to fit the S2 manifold and link pipe.
       
      So, am I right in saying that the standard cast items are quieter than a stainless system? Also, would a cleaned up standard S1 or S2 system be that much different in performance terms to the 421 on an otherwise standard VVC S1?
