Water Pump leaking

[Signature620]

I haven't done one of these on a Prostar but on most 871's you can save a lot of time by just buying the cartridge portion of the water pump and changing that (only 4 easy to reach bolts). If you have the whole pump assembly you can just remove the cartridge from it and do the same. If you do that though, I recommend buying a new o-ring for the cartridge.
