Why Does My 6.0 Powerstroke Fan Slipping? 

The main job of the radiator fan on Powerstroke 6.0 is to participate in the engine cooling system. More precisely, it absorbs the heat of the coolant used to reduce the heat of the 6.0 Powerstroke engine. 

However, if the fan of Powerstroke 6.0 goes bad or slips, it can’t pull the air through the radiator, and the issue of engine overheating occurs. It comes into action when your car’s engine is idle, or the vehicle is at low speed and doesn’t find cool air to lower the coolant temperature. 

Now, let’s find out some causes of the Powerstroke 6.0 fan slipping.

Bad Radiator Fan Clutch

If the radiator fan clutch becomes faulty, it cannot generate power for the fan. More precisely, the bad fan clutch doesn’t allow the fan to work at high efficiency. As a result, the fan may spin sometimes, but way slower than the average speed.

Moreover, the radiator fan clutch can become damaged or defective due to age or other external issues. Finally, it becomes clogged due to additional dirt and dust. 

Faulty Temperature Sensor

Before going deep in this discussion, you must first know what a temperature sensor does for an engine cooling system. To describe it simply, the main job of a temperature sensor is to measure the temperature of a 6.0 Powerstroke engine.

However, if the temperature sensor becomes defective, it can’t measure the actual heat of the engine. And, if this happens, the Engine Control Module or ECM of your vehicle can’t determine when to sound the radiator fan. 

For this, you will likely notice the radiator fan slipping on the 6.0 Powerstroke.

Damaged or Broken Radiator Fan

What if a radiator fan is damaged or broken? Well, this is not unfamiliar. The blade or blades of a fan may become damaged or broken; in this case, it can’t function properly or cause a slip. 

Furthermore, it may also happen that the electrical motor inside the radiator fan is damaged. 

Blown Fuse

A blown fuse is another possible cause of the Powerstroke 6.0 fan slipping. The fuse is connected to the motor of the cooling fan. If the fuse is blown from an access electrical short, it can cause the cooling fan motor not to work smoothly or sometimes unable to work.

Therefore, it makes a lot of sense that you will notice the issue of the radiator fan spinning due to the blown fuse. 

Broken Connection Wiring

Sometimes, the connection wiring of your 6.0 Powerstroke radiator fan may become damaged, broken, or worn out. Moreover, if this is the case, the radiator fan will malfunction, or you can consider it a cooling fan slipping. 

In the 6.0 Powerstroke, the radiator fan wiring harness is connected to the fan relay.  

Bad Radiator Fan Motor

How can you expect the radiator fan on your 6.0 Powerstroke to function smoothly if there is an issue with a bad radiator motor? Sometimes, the radiator motor can be burnt out or damaged. Due to this, the fan motor can’t work, and unfortunately, you will find the issue of the fan slipping. 

Furthermore, if you see the motor come on, but the fan is still slipping, the motor is not getting enough power.
