fan clutch noise
I replaced my fan clutch about 3 weeks ago. No surprises or problems. Since then, I thought I was having transmission issues, as it sounded/felt like the truck didn't want to upshift when I would first take off. I finally figured out today that the new fan clutch is howling for the first 30 seconds or so and then quiets down. It's a NAPA fan clutch that seems to be working properly, except for the noise that the oem part didn't make. Did I get a bad one? Do I need to be concerned? A buddy said some are noisy, some are quiet, he wouldn't worry about it. What do you think?
