what's the best way to tell if my fan clutch is dead? i've read that if i can spin it with the engine off/cold and it rotates 5+ times on its own then it's toast.
what about if it won't spin at all on its own? when i push the blades, they will only move as far as i push them and will not continue on their own.
i have also noticed that if i grab one of the blades and push my hand toward the radiator then toward the engine i'm able to wiggle it more than i would think is ok. is the fan supposed to have that much (or any) play front-rear?
the reason i ask is because when i start my car, either hot or cold, i get an obnoxious squealing sound from the front for about 1 second then it dies out. everything works fine, it doesn't make any noise when i drive it, only when starting it.
i checked the power steering fluid and it was low so i added some, but it's still there. i believe the belt is new (looks new, guy i bought it from said he replaced it) and i sprayed it with some belt dressing but it didn't make any difference either. i figured if it was one of the other pulleys then the noise would continue/increase while driving, but it's only on initial start-up.
if it's the fan clutch then i'm just going to ditch the clutch fan and replace it with an electric fan, but i'd rather not do it now when it's getting colder out if i don't have to.
