Brian, et al,
The electric fan on my TR4A is from JCWhitney. In fact I have two: one in
front and one behind, as there is no engine-driven fan and I wanted some
quick on-the-road repair if the primary fan failed for some reason. They are
as large as possible, either 16" or 20", I forget which. Under $100.
each. They are both installed using the poke-thru plastic pins. The
radiator
is aluminum.
I removed the rheostat controling the dash lights and tied the wires
together (they're never bright enough anyway, why would one want them to be
dimmer?) Installed another heater fan switch, which even has a small fan
blade
on the knob. This controls the electric fan, which I don't even turn on
unless idling or in slow traffic.
A concern might be the current load drawn by the large fan, about 10 amps,
I think. With an alternator it's not a problem, but with a stock generator
there may be a problem keeping the battery charged. Halogen headlights
also draw about 10 amps and the generator puts out around 20 amps, so you
could be in trouble right away.
Like other listers, the elecric fans have been trouble-free for years and
the second fan is simply insurance. Good luck.
