Ed, I've run a Hayden on my TR3A for a long time, and I've been quite happy
with it. Living in So CA, I sometimes drive in the desert heat, and with
the electric fan the engine keeps it's cool better than the passengers do.
It's not a cure-all by any means, but does eliminate any problems with
overheating at idle or in stop-and-go traffic.
It's effectiveness does taper off at speed, by 45 mph it doesn't do any good
at all (which is normal, you shouldn't need a fan over 30 mph). This means
it really doesn't help with the small grill openings, since they are a
problem at speed (if at all).
If you use the Hayden 'through the radiator' mounts, be sure that they go
through between the vertical tubes, and don't rub on a tube. I've used
those mounts with no problem, but a better solution might be to have a
radiator shop add some brackets to the radiator frame. That also means you
can take the fan on & off without replacing the mounts every time. I would
definitely suggest having the radiator cleaned and inspected while the front
apron is off.
The fan does draw a fair amount of current, depending on how and when you
use it, you may have a problem keeping the battery charged with the original
generator. I put on an alternator before the fan, but others have reported
'getting by' with the generator. I would suggest using a relay with the
fan.
