1. do you get your pumps from the same source ?
2. are you using 50-50 mixture ?
I replaced the factory one with the 1st timing belt (2yrs ago), mostly for preventive maintenance. Got the new pump from Autozone.
Now I have 170k on the car and the pump started weeping 5-6 months ago. I'm loosing about 1/2 - 1 qt of coolant / 1000 mi. I decided to live with it until it gets more serious... No noise or other sign of trouble yet.
