Coolant leak behind water pump

I have a 2006 grand prix and it seems that I have a coolant leak in behind the water pump, how can that be and what part is behind the water pump
 


The front cover bolts to the block with a gasket. It can leak coolant between the block and cover.

That is a possible leak if the water pump is okay. Or the other leak is the coolant elbow above the water pump leaking down.
 
Thanks for the reply, does the water pump bolt directly onto the block or is there a part between the pump and the block. The pump was recently changed by a mechanic and he said the part behind the water pump is also leaking and he would fix it for $700, but I called bs on that. I always thought the pump bolts directly to the block.
 
if the leak is from under the water pump snout and pulley, its the pump leaking, most common leak. you can grab the w/p pulley with two hands, push and pull with each hand back and fourth, it you got play the pump is bad for sure.

if you got a mirror and a flash light, you can see under the pulley to the snout and see the wet weep hole under there.

The pump bolts to the front cover, which is bolted to the engine block.
 
From further research I guess that would be the timing chain cover that the water pump bolts to. I read somewhere that you could remove the water pump and the timing chain cover all in one piece by removing only the 4 larger water pump bolts that go right through to the cover...your thoughts on this or do you know of any tricks or tips to make the job easier.
 


You still have to take the balancer pulley off with a special puller, then remove the front timing cover. And yes, just for those long bolts is all you need to take off plus the rest of the timing cover bolts.
