Do I need a new water pump?

While I understand this is immediately behind the pulley, the Magnums love to leak coolant at the timing cover where the water passages are, left and right side of the water pump. Lots of seemingly mystery seepage comes from here, and IME it won't necessarily show with a pressure tester
Look closely here and if you wind up replacing the water pump now is the time to do the timing cover gasket if it's suspect

Again, I'd only touch the timing cover if you can confirm leakage. It'll be visible if so. Otherwise, maybe just do the water pump and move on.
If you do the t-stat, you might just order a new housing. They're also cheap and yours may be surprisingly rusty. Or you can wait and see how yours is once in-hand
