I changed the oil a few days ago in my 06 lacrosse cxs (3.6l)
and checked the coolant level. It's low and even when warmed up the overflow tank has hardly anything in it.
When it cools down, all I see is some goop the same color as the antifreeze in the bottom of the tank. Almost a fist full worth of it and a little bit stuck on the sides of the tank.
The car only has 18k miles on it! There is a TSB for a coolant leak at the rear of the engine, but I haven't seen anything on the garage floor.
I was worried about the headgasket going or something causing contamination, but after reading this thread and the "mud" description I'm wondering if it's just the Dex that's the problem?
