Subaru replaced the water pump because the rubber nipple cap on the sti oil cooler port weather checked and leaked and because it is not a WRX pump.
All they had to do is put on another rubber cap that holds up to antifreeze and heat. Nothing wrong with the pump other than that cap cracked and leaking.
So the place that did the short block picked the sti pump and used cheap vacuum caps on hot coolant line.
