WK2 Water Pump and Prevent. Maint

My 2011 Overland 5.7 Hemi is approaching 70k mi.

When should I preventatively replace my water pump?

-I just replaced the main belt.

-Transmission Fluid?
-Transfer case Fluid?
-Front / rear diff fluid?

Anything else?

Thanks!

Re: WK2 Water Pump and Prevent. Maint

I can't speak for Hemi engines, but in the past with other engines I've had whenever the timing belt was replaced, so was the water pump which was usually around 60k miles.

Audi used to say 100k for the timing belt, those of us with experience knew better.

Otherwise, as long as it's not leaking out the pulley shaft bearing you should be fine.

Never. No reason to do it if it isn't leaking or failed. The Hemi doesn't have a belt so no reason to go in for that.
Come to think of it, I wonder if they are plastic impellers or metal. My BMW had plastic. At 205,000 miles it went out and there was an aftermarket stainless pump I thought about buying. Then I thought that there was little possibility that I was going to drive it for another 200K miles.

The owners manual has that info. The last two are so easy though, why not take an hour and get them done.
