On the K series its 102 deg, I guess it will be somewhere similar  but I'm sure someone will have an accurate figure.

I think the Toyota is similar to the S2 K series being on at 102 degrees and off at 96 degrees.

Not so simple. There are two fans, although they are both either running or not.  However, there are two fan speeds, depending on the temperature.  I believe the low speed starts at 98C and the high speed at 103C when the temperature is rising.  When the temperature is falling, the fans should switch from high to low speed at 98C and off at 94C.  .  A/C is a further complication, and the fans always run when the A/C is on.

Many thanks to all .
