Superspec Cooling Fan Switch

[alanrichey]

Looks like my cooling problems are because the Fan switch is not activating (shorting it out and the fan runs OK). It isn't a major problem, as the previous owner fitted a manual override switch for the fan. But I would like to fix it. I haven't taken it out yet but the trouble is that it seems to be a bayonet fitting into the radiator and all the ones I can find on the 'net are screwed in.

 

Does anyone know what car the Superspec radiator came from ? Does anyone know a source for bayonet-type cooling fan switches ?

How about fitting an adjustable thermostat instead of replacing the fixed temp one.

Alan, there was an opinion that the original SuperSpec rad was/is from a Rover SD1. From what i remember, (i've changed my radiator), it can be a bit of a swine to re-seal a new rad switch, i had to use sikaflex in the end.

 

A better alternative would be to leave the duff switch in place and fit a separate thermostat housing into the top radiator hose, you can also fit a rad switch into this and wire it to the original loom, something like this: http://www.cbsonline.co.uk/product/Aluminium_Modular_Inline_Housing_32mm_MOIN32

 

Or, another possibly simpler alternative: http://www.cbsonline.co.uk/product/Adjustable_Fan_Controller_Thermostat_STAT

 

Hope this give you a couple of ideas

Its from a Rover SD1 2000 - rimmerbros should have one - http://www.rimmerbros.co.uk/Item--i-GRID008906

Does the sensor have to go into the water ? If so what's the best method ? Although I saw on an Amazon review that he simply taped it the hose ?

That sounds incredibly sensible, glad you caught me before I disconnected it I found the one that Nigel suggested on E-Bay for £9 so I'll give that a try. If it doesn't work then I like the idea of simply adding a new housing inline.
