Bonnet does not sit right

Have you got an under bonnet picture of that corner?

The only thing there is the battery.

Is the catch that side locking off? If not, it might be pushing it back up.

 

That's all I can think of that would stop it other than the turn jacks.

Had this exact issue a couple of years ago. You really had to push hard down on the passenger side of the bonnet to close it properly.

 

Had to adjust the passenger side jack down half turn and driver side up half turn then it closed easily and all nicely lined up. Good luck.

Hi matey i had this problem. Where the bonnet locks in to the catches, there is one either side and there are two bolts on these. You can move the catch up or down. On mine one side was lose so it was locking but the the catch was sitting to high..

 

Hope this helps..

Your Rad clamp is on the piss.. That needs to sit straight really.

 

If its an after market bonnet with wont be 100%

 

Try adjusting using the 4 bolts at the back of the bonnet. Theres 2 either side. Loosen all of them off but not so loose you can wiggle them just enough so you can slide the bonnet around but some small force.

close the bonnet (but not shut) and spreading your arms across the bonnet 1 hand either side and slide it around till it looks better. Lift the bonnet, tighten the 4 bolts back up and properly shut to see it its better.

 

Had to do that with mine as best I could.

I doubt the rad clamp will sit straight due to the square corner on the rad, the clamp

needs modifying and possibly making the bolt hole into a slot will help, it looks like it might

need the left side of the clamp trimming to get it to sit square. Or make new ones

 

Good luck with getting the bonnet to fit properly, can't add anything to the suggestions

for that

I'm out of ideas with this I really can't work it out. I have straightened the radiator clamp as much as I can. The radiator is solid it's not going anywhere.

 

I tried twisting the rubber stops, I tried loosening the catch and pushing it down a bit. No change. I can actually see through the gap into the engine bay and the bonnet is not even touching the rubber stop. Could it be the radiator itself getting in the way? Mine is quite big and that raised section that is in the way of clamp looks like it could be close to the bonnet. Are all the radiators like that or have I got a badly designed aftermarket one?

If you want to rule out the radiator:

 

Put a few balls of bluetac along the forward edge (small ones, about 5mm in size) and close the bonnet. If they are still balls when you open the bonnet again, it rules out the rad. If not, there's your problem.

I didn't check the bolts that attach as the problem seems to be at the other end. Perhaps I should though.

 

Good idea with the bluetac. I will try that and then the bolts and report back.

 

Yes the problem is at the bottom, but there is a bit of movement at the top where the bolts are which will cause an alignment issue of not done correctly.

 

I spent several days trying to sort my problem out.

Exactly like yours but the other side.

 

I ended up with the strut brace off, my homemade air box off, lights out and bumper out to find it.

Even stripped down the locking attachment to clean it, needed it too.

And still couldn't solve it until I loosened the bolts and it closed perfectly.

So spent several hours trying to line it properly and tighten the bolts which was a nightmare on my own.

 

Sorted it now, roughly :/

Simple test, if you press fairly firmly, but not with all your weight, on the corner that isn't sitting low enough, does it sit flush, then spring up again when you let go? If it does is the whole length of the bonnet flexing to achieve this? If so the problem is most likely at the hinge end. If not you could remove the LH headlight and the battery and see and feel what's obstructing it. Remove the rad cap and see if that alters things, if the problem is at the front end. My old MKIV used to sit high unless slammed violently due to maladjustment of the latch on the front panel. It just sat on the latch which never fully engaged unless slammed down. I eventually fixed it, after getting funny looks doing Basil Fawlty acts to close the damned thing
