Citroen DS under bonnet insulation

As my DS has a NOS bonnet, I did not want the hot engine to damage the paint.   The Citroen DS under bonnet insulation not only protects the paint, but also reduces noise.   I was also told that I was missing two brackets that help hold on the insulation.

I was able to purchase a good used pair of the brackets and have some help to get the bonnet off to install the insulation.   It comes in three pieces so is quite easy to install.   As can be seen in the picture, it does not cover the whole bonnet, as the engine is very far back in the DS.   The un-insulated section is above the spare tyre and radiator chute.

The most common way of attaching the bonnet is to use contact adhesive.   I was advised that sikaflex would more likely hold it in place with all the engine heat.   This isn’t something i’ll ever want to remove either.   With the bonnet off the car, it was very easy to install the insulation.   With the right brackets and screws, the securing plates went on quite easily as well.    I understand why my car was missing them, as they are probably not necessary if the adhesive is good enough.   Nevertheless, I am glad I have purchased them, as I would prefer the car to be correct and as designed.

It was easier to remove the bonnet prop to fit the insulation as it is one bolt.   Not pictured here are the hoses for the windscreen washer.   These hoses push through two holes that need to be made in the insulation.   I was quite impressed with the quality of the Citroen DS under bonnet insulation.   The insulation on my old bonnet was in poor shape and coming apart.   While I was doing this job, the suspension boot on the front passengers side was being replaced.   As a result of this fix, it should stop the LHM puddle under the car each time I drive it.
