My electric fans use to kick in at 210 but not sure what temp it has to get to now to kick on. My car got close to 300 idling in the driveway before. This caused the car to overheat so bad that steam was coming from the overflow. This is why I have hooked up a bypass for the electric fans and constantly monitor the temp. Once it gets around 210 i flip the switch.

Normal is 89C (192F).

Here are the specifications.
The ECM commands Low Speed Fans ON under the following conditions:

• Engine coolant temperature (ECT) exceeds approximately 106C (223F).

• A/C refrigerant pressure exceeds 1 310 kPa (190 psi).

• After the vehicle is shut off, the ECT at key-off is greater than 140C (284F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.

The ECM commands High Speed Fans ON under the following conditions:

• ECT reaches 110C (230F).

• A/C refrigerant pressure exceeds 1 655 kPa (240 psi).

• When certain DTCs set
