installing a new Aisin water pump on my 78z and noticed in this orientation the weep hole is on the top. Not sure if I ever saw a top weep hole but possibly in other applications this same pump would be oriented 180 degrees out. Original pump has hole on the bottom. Cant see where it would make any difference but wanted to get other opinions.

Nothing at all wrong with the weep hole being on the top. I've seen them both ways through the years and have seen both positions leak coolant (eventually) and never saw any room for concern about the weep hole position. Aisin is a good brand. Z man of Washington
