Background: Noticed that my thermostat housing was leaking and issue with the alternator. While looking at the leak my fan pulley had some wobble. Thought it was the pulley out of round.
Action: Replaced thermostat housing and thermostat; new alternator; new fan pulley. All went together fine but the fan pulley caused me some concern. It seemed to rub the bottom pulley on the harmonic balancer. Didn't think much of it. Fired it up and the contact was obvious. Shut her down and removed fan. Manually again rolled the pulley and it does touch and seem to have a wobble. I had checked the original and new pulley for round. No gaps when placed on flat surface.
Recommendations: I am thinking the water pump shaft or the fan attachment device/"star" are out of round. New water pump? The shaft seems tight, not sloppy. The current water pump I believe is the original. Anyone have ideas or thoughts? Make sense my explanation? Thank you.
