Coolant leak on Driver's side leaking down to under the car

[LaCross]

I know there are a few threads on this, but i have some questions that arent answered.

The coolant seems to be coming from behind that black box with several wire coming out of it, under the intake.

The plastic tube more toward the front of the engine doesnt look to be leaking, only the rear area of the engine is wet, and it is not wet where the head meets the block.

Does anyone have a diagram of how the actual hoses are routed? The parts diagram doesnt give the best view. Or if anyone could look into their crystal ball and tell me which hose is leaking thatd be great

hose 22 and 23 connect to the heater core. You can remove the idle control valve pretty easily and look down underneath it to see if these two hoses are causing a probkem.

You likely have an old hose that is cracked at the hose clamp. Start there and eliminate what is couldnt be. If one hose is bad, there are probably more in similar condition about to go bad.

hose 22 popped off the plastic piece...didnt even break, just popped off
