Do you know what an ez-out is? They are designed to remove bolts with the heads broken off.

Normally you'd have to drill a hole down the middle of the broken bolt (the hard part), but with the nozzle you already have a hole.

If you don't know what it is, go to any automotive store and ask for it. Tell them the size of the hole (~1.75mm)

You can probably also get them at most hardware stores.

Find something that fits up its hole before you start, small drill bit or whatever so that you can try to turn it when it is hot.[/QUOTE

Will do and thank you for the advice.
