Ya, that is a weep hole that lets you know that your impeller shaft seal has gone bad.

Sounds to me like a leak at the water pump cover leaking coolant. Good thing you asked. I would take a look at the impeller as well change the o rings while your at it. :devil::thumbsup:

Thanks Guys, just orderd new seals and bearings. hope it is all that is wrong. :thumbsup:

mine was probably just oil seals (03 450 ...) but I changed my bearing too ... bearing actually looked good when I changed it...a 'bit of a pain to get to.

You will be good to go once you replace them, been there done that..... Nice heads up move to notice the leakage... :thumbsup:

:applause:just finished replacing both seals and the bearings, no problems. thanks for the info and all is well. now i just need more engine ice. :devil: thanks for the info all, it helped not going in blind. :thumbsup:
