Q: Where Is the Cooling Fan Switch Typically Located?
A: The cooling fan switch is usually mounted on the radiator assembly.
In some third-generation Ford F-body models, the cooling fan switch is on the engine block near the starter or on the passenger side head between the #6 and #8 spark plugs.
Normally, the cooling fan switch has two wires. The fan switches on to cool the radiator down, and you’ll normally hear this switching sound as you drive.
If the cooling fan switch fails, the most common symptoms your vehicle might exhibit include intermittent fan operation, an illuminated check engine light, and an overheating engine.
Tips on How to Access the Cooling Fan Switch
In most cases, the cooling fan switch has a wiring harness that should be fairly easy to spot and remove from its slot.
But before you remove the switch, it’s important to drain coolant from the radiator, which you can do by removing its drain plug.
Once you’ve removed the switch, you can proceed to test it for continuity with a digital multimeter.
