Hey just wondering if anyone has dealt with a similar sound before. My Land Rover started making this ringing sound about the time my serpintine belt decided to shread itself but they may or may not be correlated. The sound continues slightly after the engine is shut off. I don’t think it is speed dependent. Any ideas would be appreciated, Thanks.

On of your pulleys is shot. Take the belt off and check each one by hand for play. Also check your fan clutch
