Hi. Is yours the early standard viscous type that is basically a damped turbine that just has one speed or is it the later temperature controlled big nut mounting type? . 

The early type is found on many cars from the 70’s not just Vauxhall’s and is a pretty common unit .they are available new as far as when I last looked but not cheap. ,.they tend to go slack and rattle.not much you can do to repair them I don’t think.

the later type was fitted to lots of 90’s onwards Vauxhall’s ,Carlton’s,mantas,monza,senators etc and maybee other makes too. They have the metal strip across to open or close a valve to let the viscous fluid through. They is i beleive another similar type with a coiled spring too. They should be readily available new or used I would think. Il have a look on ebay later and see what’s around .

this type can be made solid rather than viscous by drilling a couple of holes through it and bolting the unit together ( internal disc to outer casing) this can be a permanent fix if you want and would never let the engine overheat albeit at the expense of a very minor increase in fuel consumption and fan noise ) no issue in my opinion others it may be !

Just had a quick nosy now. Lots of the later types on there both new and used . Found 1 early type new for a hillman but has water pump as part of the sale so a bit dear as it is

I just searched for 

vauxhall viscous fan

and lots came up. Make sure it’s a 4 bolt fixing .m pretty sure ones marked frontera or omega a are the same although some look like a 3 bolt fixing. If you get a uk seller you should be able to confirm mountings and dimensions. 

The water pump fitting should be the same

Try typing 


That’s also nice to know they may  be fixable
