450 leaking antifreeze

It's dripping off the end of the fan shaft. I take it needs a new water pump?

All you should have to do is tighten the jam nut behind the fan blades. Very much like tightening the packing on a water faucet. The nut does not have flats on it just notches and made out of brass. You should be able to use a channel lock pliers to do the job.

What Don says, but add a drop of loctite on the threads. I had
a new water pump that unscrewed itself.

Cool thanks

My 450 has two grease zerks in that area. Mine was leaking and I gave it a couple of shots of grease and it quit leaking.
Good Luck

As Don said, tighten the packing nut, but only as much as it takes to get it to not leak. Too tight can become a problem also.
