fan clutch question
- Thread starter larsen101
- Start date
A typical Ford fan clutch is engaged for the first 30 seconds or so.
You've probably noticed it roaring until you go a short distance down the road. Normal.
Then, it uncouples and the roaring ceases because the fan is now free-wheeling more than it is being spun by the belt (but it's still spinning).
The way to tell is if it will spin by hand with the engine stopped. It won't continue to spin, but you can spin it and it feels dampened. If you can't spin it, the clutch is stuck engaged, which is what it is only SUPPOSED to do if the radiator gets real hot.

My truck was running hot in town before I changed my fan clutch. When I spun it by hand, it had some resistance.

Must be a pretty wicked electric fan to outcool the factory fan.
