Did you know... there are 6 (ayup,
six) different alternatives for the radiator fan setup on a 140 with B20? No? Well, you certainly know it now.
But alas, as my psychic powers are feeling the economic downturn this evening, and I know not the chassis number of your car nor anything else about your fine vehicle, I am unable to divine which of the 6 fan setups you have.
So... if you're looking to replace the fan &/or clutch, best starting with having a look/see here, and saving this file. It
will come in handy.

Now, when you get to Sida (page) 8 in Grupp (ie Group) 2B of the parts book, you can see the Alt 1 to Alt 6 part numbers. On sida 9, there's a diagrammatic view of the various fans - some with clutches, some without.
Cars in OZ often got the 'tropical climate' fan pack, which is the Alt 6 contraption. The clutch originally had the part number 687133, but this was superseded by p/n 1266788.
And if you have that one, you're in luck! (sort of) CVI has them, but for $161.29 USD plus postage.

But you never know! Somebody, sometime in the last 44 years may have snuck an Alt 5 abomination in there.
Quick fixes? None that I know of, really. Except clutch replacement.
