Hey I just saw your message about the taurus fan. I did end up doing it finally. It works fine for the most part. My temp controller to switch the fan on didn't work... and I never really put in a new one. I"m in Japan now and my truck is home in Indiana... but I'm pretty sure I had it set up come on low speed at start up.. and had a toggle switch to change it off or to high speed if I needed it. Having the fan on is almost not necessary unless you are at a stop and it's hot out.
