There are actually at least 2 types of fan clutches.  Thermostatic and viscous.

The thermostatic type engages as the temperature of the air passing over it increases thus making the fan turn constantly when the radiator is hot. 

The viscous type only drive the fan when running at relatively low engine speeds thus reducing the horsepower required to drive the fan. 

I  don't think either would be of much help with a standard fan but may be an advantage if a large aftermarket fan was being used.

Harold, what would be the purpose of installing a fan clutch, assuming you can find one that will fit?  Do you really need to disconnect the fan so the engine warms up faster?  Once at operating temperature, the fan clutch is engaged; it won’t help a Healey run any cooler, which is generally our bigger concern.

Bob,

 

Is there a fan clutch available that will fit an Austin Healey? There is very little space between the water pump and the radiator.

Anyone fitted one to a Healey? I see they're available for various Brit 
cars, including Jags, Triumphs, etc.
