Just got a 64 reg 500 Lounge twin air, and as with all the other Fiats we get, we are installing twin horns The only space available appears to be behind the (as I can best describe it) windscreen wiper grille at the top of the bonnet.

To save me some time, can anyone let me know what screws or bolts or whatever need to be undone so we can remove this grille, or at least open it up enough to get behind it?

Thanks

My guide(username changed) on Front shock absorber replacement shows how to remove the trim panel and further down how to replace it.
Look in the "guides section" as I can't post a link yet

Hope this helps.

Remove wipers. Two little plastic twist screws and a small torx one in the middle. Lifts off and you just disconnect the washer pipe. 5 minute job.

In the real world, those little plastic twist screws are single use jobbies; if you reuse them, the grille will likely wobble about a little after refitting.

The easiest solution is just to replace them with proper bolts, nuts & washers.

That's very true. I' having a new windscreen fitted on Friday and I've already taken it off and lost one of them. I have some little push pin things that expand when you push them down that I bought when I repaired my Nissan Juke, I'm going to try those.

This is the guide link if you've not seen it;

may have changed a bit since my date of manufacture?

Just to say that the little push pins from my Nissan Juke repair which apart from being 6mm which was a too big size worked a treat holding the panel in place. I just used a drill to make the holes slightly bigger to fit them in.

Just remember some rust proofing too?

Thanks to all of you for such helpful answers, would have replied before but didn't get a notifications of replies on my email until today.

They are plastic.

Sorry it was the trim panel you drilled out not the metal work?

No metal work. The trim panel fits onto plastic underneath.
