Fan clutch options

So I’m not running A/C and I believe what I have here is a factory original thermal fan clutch for an A/C car since it has the spring thingy. Not sure if this is a good functioning clutch yet and don’t want to find out necessarily. Would rather just replace it at this point in my build. Although it does not spin easily it does spin. I curious as to how these things would fail actually.

Any good purchasing opinions/options for an OEM viscous/torque style fan clutch?
