Make sure it is your waterpump and not a cheap pipe first. The leak I had was the lower rad hose, where it connects at the t-section near the top on the left. You couldnt see the leak to start off with, but I obviously knew about it as it got worse and could see the coolant coming out. The way it dripped down was then onto the alternator.
Its quite a common part to go apparantly, as the hose section is kind of moulded on, and this just disintergrated on mine.
This is just another option for you rather than splashing out on the waterpump only to find its not that, but only a simple pipe
Bit weird
