Cooling fans in vehicles typically activate when the engine temperature reaches around 190°F to 220°F (88°C to 104°C). This range can vary based on the vehicle make and model. For most systems, the fan helps maintain optimal operating temperatures and prevent overheating. Always consult your vehicle's owner manual for specific temperature settings.

What temp should cooling fan come on 98 Chevy venture 3.4?
The engine computer (PCM) operates the fans by opening and closing the ground for the fans. The PCM will command the low speed fan to come on when coolant temp exceeds 221 degrees.The fan should always come on whenever you turn on the A/C no matter the engine temperature.The fan will also operate with the engine off when the engine coolant temp is over 140 degrees.The PCM will ground all 3 engine coolant fan relays when the coolant temp is 235 degrees or the A/C pressure is too high and run the fans on high speed.
