another bolt focc-up ideas?

[Val]

I have tried Torx harmless approach as proposed by a guy on some other forum and it worked thank you Lutin for your help  :thumbup

Bought for £4.61 set of good hard steel [url=http://"http://www.amazon.co.uk/gp/product/B000LFTRYE?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00"]Torx bit sets[/url] yesterday.

They have arrived today. I have embedded T27 which is 5mm but has managed to tap it in 4mm hole with the hammer. I was a little pissed off so may have not been so gently as advised.

Anyhow after soaking with penetration fluid and waiting for 2 hours for my radiator to cool off after the ride, I have tried using about 1 foot long arm doing most of the pressure pressing with my right hand towards the bolt and actually untightening very little with my left hand. It bulged half a mm. I have tighten it back. Than untighten again a little. You got the mood.

It worked ;D

I have new ugly radiator cover mounted! Ugly because the fit was not ideal and it bend. Frankly I do not care  :lol
