What should the temp be for a thermo fan?
Surly there is a recommended temp if i put an 85 degC thermo switch in the bottom of the radiator i guess the block temp will be well over 90deg leaving the motor before the fan decides to start. Here is my hi/low speed Falcon AU fan setup controlled by an Autronic through a modified fuse box (for dual fans) and stock ECU temp sensor in my S15.
