More helpfully, if you take the front airbox cover off and undo the self tappers you can lift the air-scoop out. That gives you much better access to the hinge bolts both from the airbox aperture and the front of the car. Taking it off is the easy part - getting it back on and adjusted can be a bh!

Right at the front bottom of the bonnet are the hinges you need to undo them and take off the bonnet its a 2 man job, I changed mine to quick release ones years ago so much easier, can not remember where I got then from might have been Steve Heath

There you go, so much easier then the standard one you just undo the bolt at the back and the bonnet slides off, when you want to put the bonnet back on there is a sleave that slides in the front of the hinge a bit like male / female type thing which the bolt screws in and pulls the bonnet into place and it can be done by one person

Well, here we are again, 6 years down the line, and I've eventually managed to remove my bonnet.

I've resurrected this thread as I've realised that some of the previous advice was not pertinent to my baby.
This work was carried out on a 2001 Series II 4.5
So, as usual, just in case there is someone that knows even less than me, here is what you do do...

The bonnet has a bolt in each side of it which are bonded into its inner sides.


They are NOT for undoing but pass through a banjo bolt, on which the whole thing hinges.There is a nut on the inner side of the banjo and a locknut (10mm) on the outer side.
These are used to fine tune the lateral adjustment of the bonnet's seated position.

Each of the Banjo Bolts screw into a bracket and can be adjusted in this position to fine tune the longitudinal positioning of the bonnet.
The threads of the banjo bolts each have one locknut on.


The brackets fit onto both sides of the outer air filter scoop moulding.
The brackets themselves have two bolts tacked onto them.
These are NOT for undoing either but have two disproportionately large washers and a 10mm locknut, on their respective threads, on the inside of the air scoop.


It is these two nut/washer sets which have to be removed in order to free one bracket and then allow the bonnet to be slid off the remaining bracket.

You can either approach these nuts from over the 'mouth' of the bodywork and squirrel around the front side of the air scoop (requiring a universal joint on your ratchet extension) or go in through the top half of the 'mouth' and try and undo them blind.

Because I'm right-handed and the fact that the bonnet support is on the driver's side helped me to decide to remove that side first.


If you have a well-trained Octopus as a garage mechanic then I am sure that you will have more hair left on your head than I did by the time my nuts came off. rofl

I remember taking mine on/off with the wife helping! Fairly logical if you take your time.
Make some easily removable marks to make alignment easier when re-fitting - this was essential for me.
In retrospect, 2 helpers with the bonnet would be better as just keeps things more steady when aligning it up again. Decent ratchet spanners and new nylon nuts help.
