When should a car fan come on?

What is the difference between cooling fan and radiator fan?

The cooling fan is also known as a radiator fan because it's mounted directly to the radiator in some engine layout.

Should both my radiator fans turn on?

Both fans should come on when the A/C is on. If one or both fans fail to come on, the lack of additional cooling provided by the fan may cause poor A/C cooling performance, and it may cause the A/C compressor to overheat and fail. The engine may also run hot and overheat, too.

Should both fans run constantly?

It can be normal for the cooling fans to run constantly under certain conditions. If the car is hot enough, they may be barely keeping up with demand and stay on. Also, most cars will run the fans at a high speed if the A/C is turned on.

Can cooling fan cause check engine light?

Intermittent aside, if your check engine light comes on while you're driving, it could mean your cooling fan switch is failing. Even if that isn't the problem, it's crucial to bring your vehicle in right away for a diagnostic check, as the check engine light means something is wrong no matter what.
