thanks. I've found a water pump that claims to be for the 97 XV10, i'm hoping this section (blue arrow in picture) is the corresponding vent port location.
This engine's timing belt and water pump were replaced within the last three years, so i'm not going to replace the timing belt. I'm a bit surprised that the water pump has failed so soon, actually. Must have been a cheap unit. If anyone has any particular tips when doing this job, please let me know.
thanks
