I am installing a 160 F thermostat on my car tomorrow. I have a hypertech programmer III and was wondering what i should set the fan timings on. Install University (which i trust) says to have them kick in at 160 F too. However, I heard from another source you should run them at 195 F... any comments or suggestions are much appreciated. Thanks.

i think stock setting is 195. You should set them at 160.

I think 160 is too low - they'll run constantly. Mine run A LOT and have them set to:

Fan 1 on 184/off 175 low speed fans
Fan 2 on 194/off 185 high speed fans

Pretty sure if you check the HPP3 site that's what they recommend for the 160.

I have mine set FAn 1 on at 185 off at 180, fan2 on 195 off 186. The car runs at abo ut 177-183 most of the time

160 is way too low. They will never shut off.

Fan 1 on 184/off 175 low speed fans
Fan 2 on 194/off 185 high speed fans

Is correct

ok well i delayed the install til tomorrow, so ill probably go with that setting if hypertech recommended it. I can always switch it lower if i want. Thanks guys!

Hypertech ask for the thermostat size, which will be 160, so select 160 and it will do the rest. Very different from HP Tuners, where you can select & edit all the other parameters. Like you said, you can always change it higher !!!
