Help with coolant leak

I just purchased a 1997 Grand Prix Se with 145000 miles on it.When we brought it home the other day the radiator was full.This evening went and looked under the car and there was nothing on the ground.Started it for about 5 minutes and then after I shut it off there was a puddle about 5 inches around.I cannot find anywhere it could be leaking from because it seems to far back to be from the radiator.The fella I got it from said he thoguht it was a water pump and replaced it before I got ithe car.It is currently at the shop being looked at but I thought you guys may have an idea or 2.I am just hopeing that its not anything major the car runs great .Any help would be greatly appreciated.Thanks...Dont know if this matters but the car does NOT smoke at all.

well. when he replaced the water pump, he could have not tightened down a new hose clamp? properly torqued the bolts? broke a coolant elbow?

could be a few things.....
 
Or he could have not put thread sealant on the bolts when he installed the water pump. Could be a bunch of possibilities.

The bolts go directly into the coolant passages. Sometimes you can do them without sealant and they won't leak. Sometimes you can do them with sealant and the will leak. In my opinion, it is a bad design to have bolts go directly into a coolant passage. But what do I know. :th_scratchhead:
 
Well the shop found a leak at the elbow so as I type they are refilling the system and presure checking it.Hopefully that will be all..Thanks for all your ides.
