Pontiac Repair: 2003 grand prix 3800, upper intake manifold, 3800 engine

Question
I have a leak in the front left are just behind the light (only during and after running not when idle).  It appears to be from a cap just behind a cover.  When I look from up top, I see no evidence of the leak.  The fluid appears reddish but the tranny is much further back.  Is this just simply a loose connection of some kind?  Thanks

Answer
Hi Andre:

what light? (left) meaning drivers side?  The dex-cool coolant in these cars is red/orange in color. If it's a 3800 engine common things to leak are the upper intake manifold plenium and or gasket those are on the left side (drivers) and the water pump and or coolant bypass pipe in the intake manifold those are on the right side of the car.
