the engine is a KA24E. The Rad fan is always running, and is running off the engine continuously. When the rpm’s are up, the fan speed follows the rpms of the engine. Its very annoying, very loud, and drags the car and robs hp. Anyone ever had this issue? i think its a defective fan clutch , Please tell me your opinions of it and if you know what it is. with a wayy to fix it. thanks. ---

You can run it no problem. It’s not gonna cause damage, just be really annoying and loud. ---
