Time for another update...(same as the previous update.)
I have 190,000 miles on the mechanical fan installation, (240,000 miles on the JK).
Whether it's -30°F or +95°F outside, the transmission continues to run in the 90°F to 130°F range; the engine continues to run in the 195°F to 200°F range;
the heater and AC continue to work well; under-hood temperatures remain much cooler than before the installation.
Still running the original water pump.
Average gas mileage is still approximately ½ mpg less than the long term average before the installation.

Just FINALLY installed the mechanical fan and shroud on my heavy 2007 JKUR. The reduction in temperatures was amazing. Have to see how it does on a hot and high trip but so far, so good. I wish I could still find the electric fan to run in tandem but I'm having zero luck.
