I have a 2003 Grand Prix 3.1 that has been losing coolant, so I just pressure tested my cooling system and I can see a leak. The only problem is I'm not sure where it's originating from.

If i'm standing in front of the car, the oil pan is on the right, and the dripping is coming out just to the left of the oil pan. Anyone know what would be above that and leaking coolant?

Thanks for your help.
