Unhappy Coolant leak?

So, my 02 SLE seems to be leaking coolant from somewhere. I can smell it immediately after driving the car, and my over flow reservoir is constantly low. It'* not leaking when the car is parked so it must be leaking only when the engine is running. When I took a closer look, the upper half of the intake manifold on the passenger side looked wet with residue around it. Are there any common places for the 3800 series to be leaking coolant over time? I checked all the hoses and coolant lines, and they seem fine? Any input would be greatly appreciated.

Thanks in advance.

There'* a elbow from the LIM to the water pump on the passenger side. A bit hard to see so you may have to get your head under there. It'* plastic and has rubber O rings

Will the fitting that you have in the picture fit my application? I haven't removed it yet, but that definitely looks like where my leak is comming from.

Yes, those elbows fit all Series 2 motors.

Easiest way to change out the elbow is to remove the alternator and it'* bracket..

Word of advise....those rubber o rings in the help kit are useless and will start to leak in a few months. I had to pull mine back apart and resuse the factory o-rings and then silicone the heck out of it to get it to not leak. I tried getting rubber o-rings that I could use as a replacement, but didnt have any luck.
