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.

I didn't see one. Moss has them for various Jags, Triumphs, MGs, etc. I 
was just wondering if someone managed to fit one to a Healey. Not sure 
if it would help hot running or not.

Fan clutch really is a misnomer, it's a viscous coupling that prevents the
fan from spinning too fast.

Bruce,

I will admit a thermal fan clutch is a nice to have and not a must have.
The biggest benefits are less engine noise and better economy (i.e. less HP
loss) when the clutch isn't engaged. As I mentioned previously I doubt one
exists that is thin enough to work in the limited space between the water
pump face and the radiator. If anyone finds one that fits a Healey please
pass on the information. Here are a couple of pictures of a typical thermal
fan clutch for reference.

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.

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.=20

The viscous type only drive the fan when running at relatively low =
engine speeds thus reducing the horsepower required to drive the fan.=20

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.

There may be a third: I inherited my parent's 2000 Lincoln LS; it has a 
hydraulically-driven fan powered by a pump that is nearly identical to 
its power steering pump. Near as I can tell it has a bimetal valve that 
gates pressurized oil to the fan, which has a kind of turbine (it looks 
a bit like a clutch fan; well, I guess it is). The car would overheat at 
random and had to be towed a couple times; eventually, there was an SB 
and we replaced the 'clutch,' and it's worked OK ever since. I only 
recently learned why it had such a goofball setup: The early versions of 
the car had a wimpy alternator which couldn't supply enough power for an 
electric fan. Why didn't Lincoln just use a better alternator? Well, 
under the skin the car is essentially a Jag S-Type from when Ford owned 
Jaguar; this somehow seems like a very 'British' solution.

Aircraft engines, most of which have oil coolers, often have a 
'vernatherm' in the oil cooler circuit. It's bimetal, I think, and 
closes when the engine is cold so the oil can warm up quicker. I think 
some oil cooler systems in cars use something similar.

I asked about a fan clutch because the best solution I've found for a 
Healey overheating at idle was a SS flex fan, whose blades flatten at 
higher engine speed but would still offer some resistance at high speeds 
(but it was annoyingly noisy). A fan clutch /might /offer less 
resistance to airflow through the engine bay, but I haven't had much 
issue with cooling at highway speeds. Moss offers clutches for various 
Brit cars, so they do have a place apparently.
