Don't know why, but I cleaned and painted up a front crank pulley and bolted it on. It's black and helps break up some of the red. What is that, the P/S pulley? I don't even know. It's on there now. LOL
A month later: yes, the black thingy is a power steering pulley. I'm not sure what A/C cars used, or A/C cars with power steering. Would have to have been a multi-groove pulley.
