Default Mysterious coolant leak...

I've been going thru coolant on an unusual level lately and I think I found the leak. I was testing my new ramps out for fit of the 315's and clearance for the front. When I was checking the front I decided to crawl under... that's when I noticed green drops falling... yes I found a leak!! I have no clue where it's at exactly just a general area. It appears to be coming from one of the lines that runs from the oil cooler up to the front of the motor? The coolant is dripping from the passenger side of the cross member. I cannot get a clear view of that part of the car, I am going to go out and take pictures shortly.

Any Ideas would be great! I'll post pics A.S.A.P.

The oil cooler line is connected to a "T" in the heater hose. It's hard to see from the bottom but you should be able to see it from the top looking from the passenger side. Might be a loose clamp or split hose.

Default Leak Found

After extensive searching I found the leak by pure luck and some help from replies It appears to be a small steady drip coming from the p/s of the water pump where it mounts to the block... this gives me a chance to swap the belt tensioner too. I observed the T hose.... looks okee dokee for now

Thanks all who gave advice!
