I've done a few kenlowes for members, and had the fan off mine Toooooo many times.
contact Artic for a good price on a spare two speed OEM fan he has would be my advice.
Fan change is:
front bumper off
slam panel and headlights off
cut fan shroud around ircon pipes and remove shroud inc fan
remove fan from shroud
Either fit repacement 2 speed exactly as existing was fitted
or ftr replacement kenlowe following inst given.
Are you anywhere near the Wolverhampton nano meet on the 16/17 Sept, couple of us could do it with you and guide you through it, Failing that i am at the Doncaster meet tomorrow rebuilding a fan for a member there, wont have time to do another in the day but if you were there you could observe
