my waterpump is leaking constantly through the little hole on the back of the waterpump.
i took the front cover off and it looks brand new in there, are there seals behind it that can be replaced? or is it a second hand unit?

Thats a common problem as most here will agree.. The mechanical seal behind the rotor wears over time and coolant seeps past.. Either live with it if its not too bad(but DONT seal the drain holes or youl have coolant in your oil), or buy a new pump a great expense...
