How thin is that elbow? Is this the coolant elbow from the LIM?
And yes, A/C refrigerant leak dye mixed with condensate can look like antifreeze.
Thanks for everyone'* thoughts. I am afflicted at work for planning to go to Myrtle Beach in 2 weeks. I literally have not been home in the daylight to pull everything to get a good look, and give you guys informed symptoms to aid in your much appreciated assistance.
For full disclosure, I have two achilles heels in the car.
1) I haven't put dye in the A/c in 3 years. We found the tiniest leak in the evaporator. I have been living with it for the past 3 seasons by putting in a 2 stage leak stop and charging it. i have been lucky as it has held through the seasons with an addition of one can of al34a in Aug or Sept in each year. Odds are it is pretty close to being below useable level by now.
I'm as certain as i can be that I'm seeing coolant. And it only looks scary when the drain tube dumps water on itand dilutes it into a bigger puddle. I have had neither the heat or A/c on for a couple of days, and find barely a drop or two on the ground, if any.
2) I had the plenum and the upper gasket replaced about 30k ago. I wasn't here yet, so I didn't know to go after the LIM at the same time. At 165k, and from what I have collected here, we can be pretty sure that thing is mush by now. I have wanted to go through the process of replacing the 2 gaskets and plenum with the recent GMs and a Dorman. I'm just not comfortable doing it without informed supervision. I have approached the Philly legend 95naSTA, and he'* agreeable. I just haven't put us together yet.
So, it'* a coolant leak that is showing itself on the rear, lower, passenger side of the engine, ie the line described above. The water pump, and the LIM, present themselves as prime suspects. A living-in-denial possibility could be a coolant hose leak to the heater core.
I have to get my FSM, and pull what I need to pull, to get a good look. Short term ,I think I'm OK. Operating temperature is normal, coolant level hasn't visibly changed, I'm getting no white sweet exhaust, and no Hershey milk in the oil.
Didn't mean to be so wordy. I just want to respect you guys' help with a full picture. And in the next day or so, some definites on where this bleeder is.
Any thoughts are still welcome, I'll keep an eye out. And I'll pop this thread to the top, when I figure out what I can.
