Re: Fan movement question
Is it a rigid (fixed-blade) fan.... or a clutch fan.... or a flex fan? Got any pics?

Re: Fan movement question
Blade flex?
Movement of blades relative to the hub/pulley? Movement of fan/hub assembly relative to the water pump? Does it only do it when you’re playing dance music? :-)

Re: Fan movement question
If this movement you are talking about is in a circular fashion...it's supposed to do that - lol. Sorry, I couldn't help myself.
I have known clutch fans to shell out internally and get a bad wobble to them. I could even grab a blade (with the engine off) and move it towards the front and back a good inch. The clutch guts were wiped out. Other than that, I am at a loss unless the bolts are looses and or missing.

Re: Fan movement question
It sounds like a bad water pump.

If I grab the fins of the fan I can move it back and forth and up and down
