Gentlemen. One of the cooling fans has a bearing that is on its way out. Can I replace just that one fan or do I have to replace the whole fan pack? Thank you for any replies..!

 

You can replace the single fan but the whole assembly pulls straight up to come out and worked on as easier , no coolant draining needed as the radiator remains

Do not pull the plastic fan motor connector release too far out as they will break

To test the fan there is a 3 wire connector on the aft lower left radiator and a paper clip from one white wire in the connector to the blaclk wire will give you single fan

Remove clip and the other white wire to that black will give you both fans

This with the key in the run position and engine not started

This is a low current section of the fan control circuit so no arcing hazard

Sure it is the fan and not water pump or alternator ? You can remove both fan connectors and give it a try

You can put the handle of a long screwdriver up to and pressed against your ear and use it as a stethoscope to locate noise , place the tip on the fan motor

Same thing works with a very long socket wrench extension

But you have to be very careful with your hair

 

Parker 7. Thank you so much for your elaborate reply..! Excellent directions also..! Good news about having to change only one fan instead of the whole thing. It’s the one one top, it is wiggly and squeaks before the engine ignites. On a side note: I once tried to locate a faulty spark plug on a 69 gtx with my hoodie on, laces pointing down at the running fan for a brief unsuspecting moment. That won’t happen again. Again, thank you for your reply, much appreciated..!!!
