Not sure that I'm right about this but, I heard/read ? that the cooling fan
and associated assembly actually are required for engine balance, not unlike
a harmonic balancer. Not sure about that on a 4cyl engine, but that's my
recollection. Maybe that will ring a bell with someone??

Subject: [Healeys] electrc fan vs. belt drive
I'm also on a Triumph forum where a few people have claimed that the
installation of an electric cooling fan (and elimination of belt drive fan)
has increased their Power by about 7%.
They claim that the drag created by the fan on the waterpump pulley creates
a power loss that is more than the power loss due to the burden on the
Alternator/generator created by the electric fan.
Anybody have any thoughts?
