Fan Mode
Temperature A/C Pressure
Primary (RH) Fan ON 109 C 229 F 189 psi
Primary (RH) Fan OFF 105 C 221 F 150 psi
Secondary (LH) Fan ON 112 C 234 F 240 psi
Secondary (LH) Fan OFF 108 C 227 F 210 psi


Additionally, the PCM will turn off the
fans at higher vehicle speeds (above 48 MPH I believe) since running fans can
actually impede airflow through the radiator at high speed. Each fan also has a
minimum running time. Once activated, the primary fan will run for a minimum of
50 seconds, and the secondary fan for a minimum of 26 seconds. Finally, certain
Diagnostic Trouble Codes (DTCs) may cause the PCM to turn on one or both fans.

Also just get the SLP fan switch and you will be good to go I put that in my car and it runs at 170 all day long

go with the above. get your car tuned to turn the fans on sooner so you dont have to make the fans turn on and off by a switch. less hasle.
