I just installed a Hypertech 160 thermostat in my 99 Camaro. I was wondering what you guys would recommend for the temperature setting on the fans to accomodate this new Tstat.

 

190 on
185 off

in florida heat my 160 stat keeps the engine temps at right around 175.

setting it to 190 will still keep you good and cool, but won't have your fans running TOO often, and decreasing the fan motor life.

set the 2ndary fan at something like 210 on and 205 off maybe
