Shane,
Thermostats don't start opening at their advertised temps. Don't ask me why but they don't. I did a test 3 years ago when I put a Hypertech 160 stat in my 2000. I tested both the stock and 160 in a pot on water on the stove. I heated them very slowly to see when they started to open and when they were fully open. I was surprised at the results.
I thought being pressurized might cause them to open sooner. Wrong.
Dealerjim autotapped my truck a few times and the constant temp was 176-177 with the 160 stat. This is even a different 160 than the one I tested in the pot of water. This happened because I tested the 170 stat out giving my first 160 away. I purchased another 160 later and this is the one tested with the autotap. The rule of thumb is the stats don't start opening until about 15 degrees above their advertised temp.
The results of the test are on my website.

FOOD FOR THOUGHT
Just thinking out loud ! I would think if the TEMPER on the little springs on those Stats were weakened due to heat then, they are compensating for it. What I'm really saying is longer it's in the truck exposed to heat-temps it has to have a bearing on the function of it opening !

The longer a stat is in a vehicle the more prone it is to sticking. You don't notice it as much when it's stuck open but you notice it in a hurry when it's stuck closed.
It usually takes years for this to happen.
The 160 in my truck has been in for about 2 years.

Thanks for the info. One more question. I do plan to do the e fan and water pump pretty soon but if I do the 160 degree thermastat now, will that help a truck with a stock fan?
Thanks, Shane
