My 1998 monte carlo 3100 is leaking coolant. Looks like the side of the engine behind the power steering pump. Any suggestions would be appreciated. I've already lightly tightened 6 bolts on the head?

 

That sounds and looks like a Lower Intake Gasket leak.
To confirm, get a radiator pressure tester, bump up the pressure (I think 12 psi would do it) and see if it has coolant bubbling out where the lower intake and the head meet. If it does, then it is those gaskets (replace sooner than later, eventually coolant gets in the oil).

 

ditto on Maniacs advice

 

what the maniac said but I would add that if you drain the system so there is only air and then paint along the gaskets with dish soap, it will detect even the smallest leak because bubbles will form
