How does a radiator fan switch work?
As engine temperature rises to a specific threshold, the switch is activated powering on the coolant fan. The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level. Once the temperature reaches this cooling stage, the coolant fan will shut off.
Does radiator fan turn on immediately?
Turn the air conditioning to the maximum setting – this should spark the cooling fan to immediately come on.
