What should I put for the Fan on/off settings for a 160 thermostat? I was thinking 165/162 for fan 1 and 180ish for fan 2.
Also, should I enable the climate control override?
Thanks,

Not sure what this would be in *F, but when I was running a 160* stat I had Fan 1 set to come on at 79* and turn off at 75*. Fan 2 turned on at 85* and off at 78*.

Fan #1 on temp=185*
Fan #1 off temp=174*
Fan #2 on temp=187*
Fan #2 off temp=183*
Keep Climate Control Disable set to "Disabled"
Also set your Ignition Off to 179* and whatever time you are comfortable with(mine is set to 120 sec's)
You might also want to change the enable speeds as well. Mine are now set to:
Fan 1 Enable: 52mph
Fan 1 Disable: 55mph
Fan 2 Enable: 74mph
Fan 2 Disable: 77mph

Will it have trouble keeping temp at 160 with the fans coming on that late?

Haven't had to touch those settings for two years now. Temp stays a lot more constant. With the factory one the coolant temp was all over the place.
Alright, I'll try those settings. Thanks for the help.

What are the settings for a 180 ?
Personally, I'd just subtract the difference between the thermostats, and then lower the on/off settings by that much (180 would be -15; 160 would be -35). Then, I'd just set the key off one at the thermostat temperature rating.
The thermostat isn't fully open at 160; it begins to open at that point. Flipping the fans once it cracks is kind of pointless, in my opinion.
Heres what I'm using with my 180* stat - works good.
