How to Fix Rotating Mini Headlight Bolts.

Mini Headlight Bolts, mainly mini models R55, R56, R57, R58, R5,9 R60, R61 (Link to part numbers) have a habit of corroding inside their housing. The headlight bolts screw into captive nuts, moulded into the plastic housing. When undoing the headlight bolts, if the bolts are seized (corroded), the captive nuts break free. You then can’t undo the bolts, as they just go round and round, without ever coming loose. They just won’t come undone!

First, a brief statement on inherently bad design issues…

When finding an issue, I’m just the same as anyone else. I’ll be scratching my head, going “what the…”. I must admit, in this day and age you would hope design issues like this would have been discovered and ironed out long before it went into production. But unfortunetly, round every corner there’s a fault or issue waiting to happen. We’re only human of course. Now where’s the robot that built this… 😃

The Bolt(s) Won’t Come Undone?

I tried to undo the headlight fixing bolts, but the captive nut just kept going round & round..?

The Four Mini Headlight Bolts that Usually Seize

The Mini Headlight Bolts and the Different Components

I tried to grab the fixing From behind, but I needed to move the air intake pipe & the water expansion chamber. There wasn’t much of the captive nut to grab hold of, and the bolt was seized tightly in place.

I failed. I just couldn’t undo the bolt!

Notes:

  • Don’t undo the headlight adjuster, (unless you’re adjusting the headlights)!

How to Get the Captive Bolt Out.

So, how do I get the bolts undone?

  1. The captive nuts are held in place by a plastic mounting bracket…

  1. Using a bit of heat (from friction). We can remove the rotating captive nut whilst it’s fixed to the bolt! For this we need a drill or a powered driver…
The Seized Mini Headlight Bolt (Removing)
  1. Rotating at speed causes the captive nut to heat up. Gently levering the bolt out speeds things up! But don’t lever off anything that can break.
