Fan turns all the time. Replaced fan clutch and it worked okay for one day and now it turns all the time again.
The fan will turn all the time. It will spin at a much slower rate when the air temperature coming from the radiator is cool enough. Once the engine gets warm enough, the air going through the radiator will make the liquid in the center of the fan clutch get more liquidy and that makes the fluid go the outside edge and "grabs" the other part of the fan clutch causing the fan to spin at a much higher rate. Sometimes you can tell by the sound difference. Because my truck has a large fan, when the clutch "engages" it sounds like an airplane powering up at take off. Unless you have electric fans on your vehicle it will spin as long as the engine is running,
Hi Fernando Navarro, I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
What about the clutch sound. I take it your fan clutch does not relax which means it is frozen. Try to spin it if it is hard to spin then it is frozen. Which in that mode your truck will not get hot but it is over working your engine. Since it does not relax. Good luck.
