Diagnosing loose fan / replace water pump FJ60

[jwould]

Was driving awhile ago and the 60 snapped the belt that goes from AC compressor to crankshaft. Snapped due to a loose bolt on the AC compressor that eventually fell out. Pulled out the mangled belt and replaced all the old ones.

Started up again and runs rough and the fan wiggles/is loose where it attaches to the water pump. See attached video (think it ought to work - embedded from YT). Thinking this is a water pump replacement but wanted to check and make sure before undertaking.

Any tips on water pump replacement much appreciated also - from perusing prior threads sounds like it might be a good idea to pull the radiator at the same time.

Thank you!

There are 4 bolts on fan to pulley, try tightening with 12 mm wrench.

Agreed. It might just be loose fan bolts.

Ditto as above. If it is the water pump it is not the worst (damn near it though) but very doable with patience and persistence. Good write ups on here too.

I have replaced three failing waterpumps, twice on my 60 and once on my sisters 62. In all three cases there was a wobble like you have and there was coolant leaking out of the front seal. If you are not getting leakage, I am betting it's the pully that's loose and not the pump failing.

Tried tightening the bolts but the wobble persists. Guessing it’s the pump in all likelihood. Thanks for the advice!

I took a look at this with @jwould . the 12mm nuts (p/n 90179-08123) on the pulley are definitely tight, and all the belts are new and recently tensioned. Possibly a lose bolt or the seat? Is the seat replaceable or a part of the pump assembly? Are the bolts a part of the seat too?
Sorry, not all that familiar with the 2F!

I think you should pull the clutch and pully off and see if you can find where the wobbling is coming from.
