Guy Broad Uprated engine fan
Hi - First post here (hoping that this XK forum is a bit more active than the other one I initially subscribed to on another site!).
So I recently brought back my Dad's old XK120 DHC and am in the process of doing a 'few jobs' whilst I await the registration process for UK plates. Has anyone any experience of fitting the Guy Broad uprated fan?
Trouble is on trial fitment (with the rad still in place just the top hose and clamps removed, the blades foul the underside of the (new, alloy) radiator.
So question is do I persist with the new fan (painstakingly removing 2-3 mm off each blade) OR stick the original fan back on? Anyone of here used the new upgraded part - is it worth the hassle? I have to think that 'fan science' has moved on a deal in the last 60+ years so wouldn't be at all surprised by the upgraded unit shifting a ton more air than the old unit........ but does the benefit out way the time and hassle to fit it?

All sorted, I 'dremmeled' (new verb) the leading edge off each blade and this solved the problem. Still had to take the radiator out though - which is a bit of a pig to do! I suspect that the difference was very small but with a midified fan and modified rad I'm not surprised there where interference issues

I will say that the air flow from the new fan is considerably greater than the old one so I'd be amazed if it doesn't help and I think is probably a sensible mod.
