Anti freeze leak

[Pup]

Well,

Had to have my rt header gasket replaced yesterday.. When we removed the pan for access, there was a slight anti freeze drip.. Never saw any spots on the floor of the garage or in the driveway. Looking up while it was in the lift, we could see the upper hose was wet, looked like the one that connect to the resivior, but not sure.. Not went in the trunk at all..

Also when checking the exhaust for leaks, with the motor running, on the life, I was hearing what sounded like knocking, couldn't locate it exactly. Was not motor, appeared to be more transmission area, but I could not tell..

Water pump maybe? Antifreeze was down slightly, until I release the cap., then it rose almost to the minimum line.

We here is the best place to buy a water pump? I assume that OEMis what i am after.

Should I do lower motor mount at the same time? Anything else?

Maybe the water pump was the howling that I have been hearing.

I have done lotsa spur he's and found a bit of info...

Looking for your help with where to begin..

Mileage is 56k, original 3.2. Runs strong ,only a drip of antifreeze.. Won't take chances..

Thoughts?
