The breaking impeller issue is generally found on early vehicles but there's no magic formula to tell if your vehicle will or won't be affected. It's not straighforward like Nikasil where the issue stopped at at specific engine number. Water Pumps can fail on any engine.
As you're removing the Thermostat Tower and fitting a new thermostat, it's very little extra work to take the pump off and check the impellar. Better to know what condition it's in than to speculate.
Note the locations of the bolts as you remove them. They aren't all the same length.

There's three 'shoulders' on the clamps. Gently squeeze the outer two together using a pair of pliers and the clamp will open.

In the photo the one on the left is open, the one on the right is closed.
To close the clamp, squeeze the centre and top 'shoulders' together.
