Frequently Asked Questions (FAQs)

1. What controls the radiator fan?

On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it's not working, the fan won't turn on when it needs to, which means the engine might overheat.

2. What are the symptoms of a faulty cooling fan switch?

Common signs include engine overheating, the Check Engine Light coming on, and a broken or shorter signal wire.

3. 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.
