Just taken off my water pump off my P6 v8. Got the short nose, not had engine running yet but there has been past water leak problems and I am unsure about the condition of the pump. I don't want to blow £115 on a new one if this one just needs a clean/tidy up. there appears not to be any damage inside and I can spin it quite easily by hand, it doesn't bind and is not loose. Is it supposed to spin freely for a short time when spun by hand ?... silly question but as I say I don't want to buy a new one if this one is ok.
