93 SC 400 - 134K Noise from the engine
I have been looking for an SC and found a single owner 93 SC 400. Drove to Louisville KY and got it to Texas on a trailer over last few days. I do hear a noise and have searched. Wondering which direction I should be headed on my research. The fans moves easily by hand. Any advice from good folks here would be great. That seems to be only blemish. Would like to get her back to her glory. Have attached few links to video uploads for the type of noise.

The sound is really loud when it starts and seems to diminish in decibels as it warms up but as you can here in subsequent videos. The first video is when the car starts.

None of the videos show as available you have them set to private.

Sounds like a bad idler bearing or possibly power steering system low on fluid.

Thanks will start on my research. The power steering fluids (All fluids) are clean and pink. I did replace them all except transmission (maybe later candidate) but not touching it now. Will research bad idler. Any part number?

Could be idler, tensioner, alternator or possibly timing belt pulleys. Easiest way is remove the drive belt run the engine very briefly see if the noise stops plus you can hand spin the pulleys to check for noise.
