Water Pump - 4.0L

My cooling woes continue.
Water pump started leaking today.
Looks like an easy job for a 2004 4.0L (at least from the youtube video's)
FWIW, I'm going with an OEM pump (for critical components I personally use OEM when I can)

Here's my question. I took a look at the FSM, and it says to (5) Remove power steering pump (Refer to 19 - STEERING/PUMP - REMOVAL).
Is this necessary? (doesn't look like it needs to be removed, possibly a typo in FSM?)

No. I'll find the YouTube video I used. Give me a Minuit.

Edit. Here is link 2004 4.0. I heated metal pipe with a blowtorch that gave him trouble. Came right off.

Yes, that's the Video I viewed (nice video).
Guess it's a FSM typo (also says 4 bolts in FSM, when it's 5 bolts).
Also, thanks for the reminder to have my torch ready for the heater hose pipe

No problem. Good luck. Maybe yours won't be stuck. A long 1/2 inch breaker bar is used on tension arm too if you don't have one. (Or stuff to improvise) I had to buy a second as I was moving when I changed it is why I remember lol.

There is no need to remove the power steering pump. Even on some earlier model Jeeps where the water pump bolts to the p/s pump bracket, you don't need to remove the p/s pump.

I should be able to use my (beam) torque wrench for that.

Check your Heater Hose Tube (Threads into the Water Pump) if it's rusty looking or questionable pick up a new one.

I just changed my water pump last weekend - I didn't have to remove the steering pump. That clutch fan was bear to get off, but after that - the rest is a piece of cake.

While I'm waiting for the OEM pump to get in, I picked up a fan clutch wrench from Advance Auto Parts (free rental), and using my beam torque wrench on the belt tensioner, I tightened the belt a little, and with a few light whacks on the fan clutch wrench (counterclockwise), it loosened easily for me.
But I'm sure I'll run into something else to cause me a headache when I install the new pump

Honestly - there's not that much to give you a headache. The biggest headache for me was that fan (and the weather!) My fan clutch nut did not want to come off, spent most of my time fuss'n with that more than anything.
Once that was off, everything was done in a couple hours.

Yes, it should be an easy job, but I'm a believer in "Murphy's Law"

Done. Put in a new Radiator while I was at it.
Easy peasy.
