Okay, so the other day I confirmed that my fan is off virtually all the time.

I recently put in a full radiator block (in addition to my upper grill block). I had turned back kind of warm that day (70's) and I had to go make a trip on the interstate. P&G'ing between 55-65 ish after a while I started to hear this wierd sound at the beginning of my pulses. After a while I figured out it was the fan kicking on.

Guess that confirms how oversized my engine is--when I have to block off the whole radiator and then drive it "hard" to get the fan to kick on--and then only occasionally.
