If you don't hear it, yours is not working. There is no mistaking it. No such thing as "I wonder if my fan clutch is working?" because you will hear it. 212* sounds about right. Even when pulling my Excursion on the first try, it brought the temp back down to just above 180*.
You just kinda proved my thought on the clutch fan. I've never "heard the fan roar" It always looks like it is spinning. I've always heard you can stop a fan if the clutch is not engaged. I like my fingers though
I still want to look into a bigger radiator and intercooler though. I haven't yet, but I would like to still turn up the power some. I won't do it though, unless I can cool it also. That's just the hp junkie in me though. I did find I could run 80 mph to North Dakota. I found that does come at a price though... Over 15 gallons in a hour.
Since my odo is off, it's hard to figure mpg, but I figure that is just about 5 mpg or little less. Across Nebraska I was at 5.1 gallons per hour at 67 mph. That is probably as flat and no wind as you can get in the US. 13 mpg
