I’m in the middle of a head gasket job. While wait for the machine shop, I figured it’d be worth inspecting the water pump while it’s accessible.
But what constitutes a “bad” water pump? Impeller erosion, obviously, but what else? Bearing play?
Thsnks for input…including whether I should replace, inspect, or fuggetaboudit!
