Time for another water pump

There's a pink puddle under my Jeep that feels slick on my fingers . Looks like my water pump is leaking.

I see that rock auto has a gates water pump for $43

And a Mopar one for $187.

Do you guys think it's worth going with the Mopar? I'm sure it's better, and I'm not keen on doing this multiple times, but that's a good chunk of change.

You can see a drip coming down here:

Hard to get a good picture, but it looks wet under the pump:

As a follow up, Rockauto is recommending that I also replace the fan clutch.
They don't offer the Mopar like this, only the Gates

Is this necessary, or would I just be replacing my stock fan clutch with a possibly inferior one?

If it were me, I'd go with the best water pump sold by AutoZone and skip the fan clutch if it is currently working.

Though I might go with the clutch if I had high mileage, say over 100K.
 

I buy most of my parts at AutoZone opting for the parts with a lifetime warranty. I've gotten good service out of most of their parts although I can't remember the last time I had to change out a water pump on anything other than my tractor.
 
Gates makes a good water pump. Just stay away from any yhat have a metal impeller. It failed fast and didn’t pump well.

As far as the clutch? If it is not broken do not fix it.

Back on the road again!

I ended up getting a genuine Mopar waterpump for only $91. It was an Amazon warehouse return (i.e. someone bought and returned it). It was a bit of a gamble, but the pump looked pristine and came with the gasket (the box itself was beat to heck).

The job ended up not being too bad, largely because of some of the tools I picked up lately.
These hose clamp pliers make life so much easier, especially on the larger clamps. They lock into place, holding the hose clamp loose

I picked up a new 1/4 torque wrench to use on the bolts. I think it clocked in at $10 on sale at Harbor Freight.

I used some thread sealant on the bolts. I've heard that's necessary as they pierce the water jacket.

and my good old hose pliers

I went ahead and used genuine Mopar coolant as well. It's only $20 a jug for concentrate on Amazon
Genuine Mopar Parts 68048953AB Antifreeze/Coolant - 1 Gallon Bottle

Hopefully I'm good for another 172k miles before I have to do this again.

I noticed what I think is another problem. My fan is fully engaged 100% of the time.
Right now the Jeep is stone cold, and I can't spin the fan by hand. If I really pull on it, I can get the entire belt to move, but the fan doesn't spin freely.

From what I understand, this means the fan clutch is bad. Does that sound right to you guys?
