That is the one attached to the rad in front of the engine. My fan is not sitting square so vibrates when switched on (never do now until sorted) so guessing that one of the bolts/nuts holding it in place has gone for a walk. Looked easy enough to remove the frame & fan which I tried to do (2 bolts top/ connector/2 lugs at the bottom) but once loose not enough room to come & out via the top so guessing its a jack it up job and try from the bottom ? Had a quick look but that route did not look that easy either. Anyone had to do this ?
