Changing my water pump, what else?

[~jeff]

Hi,

I have a 2001 Boxster S with 57k miles, and my gut tells me it's time to change the water pump and thermostat, and have a couple of questions.

I'm going to change the thermostat and serpentine belt while I'm at it, and I'm wondering if it would be smart to change the rear hoses while I'm under the car. The car is 21 years old now, and I'm wondering what the useful life of the hoses really are.

I've read a lot about coolant tank failures, same concern. What do you think?

Appreciate your responses, thanks!
