I live in Dallas and I use a Texas Cooler fan blade. I like the low noise level
but with the AC on and sitting in traffic the engine temp still rises. The way
I took care of the problem was to install an electric fan in front of the
radiator that is controlled by a thermostat. The themostat is set up to turn on
the electric fan by either engine or AC system temp. It works great!

Yes, I know all our cars are "Hot!" (a la P. Hilton ;)
But, I'm talking running temps here. Although my BJ8 has a clean block,
good stock baffling, an Excel-cored radiator, RedLine Water Wetter and a
Texas Cooler fan I still get a temperature rise sitting idle on a hot
day (it'll creep up from 180F to 200F or higher in a few minutes).
Moving temp is under control, except when pulling a grade on a hot day.
Anyway, last time I did muffler work I wrapped the downpipes with header
wrap (from good ol' JC Whitney). The last couple days, we've had
record temps in the SF Bay Area, and I've been able to test this mod.
My "data" is empirical/observational at best, but it appears the wrap
helps keep the temps under control, especially sitting at idle. It's
not a miracle fix, but seems to reduce hot idling temps by 5-10degF. It
also appears that the gas exiting the muffler is hotter (measured by the
palm of my hand). That's heat exiting at the rear instead of trapped in
the engine compartment. Looks kinda cool, too.
I agree with others that a flex fan is more effective than a Texas
Cooler-type fan, but I couldn't stand the noise at idle.
