*Leaking Antifreeze* on 1998 Pontiac Sunfire

1998 Pontiac Sunfire, leaking antifreeze, but not sure where the leak is. The coolant is dripping off of a flat metal piece that runs around the oil pan on the passenger side of the car (when laying underneath it). But as for where the leak is coming from , I have no clue. Someone told me to change the freeze plugs on it. Could that cause this problem and if so where is the freeze plug located on this particular engine? (2.2L)

The only thing I'm sure of, is don't assume anything, find the leak first. You could trace it back to the source, use a flashlight and mirror to see where it's coming from.
Sure it could be a freeze plug, but you still have to see it leak before you address it. Get your flashlight..
