Well, starting to give up on this car. I recently had my car worked on, the idler pulley was replaced per a TSB and the cooling system was bled since it was "gurgling and sloshing". The sloshing is coming back and now I am smelling antifreeze. Maybe I should have traded it in after all... I am not seeing any leaks, and there is no antifreeze on my garage floor, so if there is a leak it is so small it evaporates before it can drip, maybe it's getting caught on a plastic panel under the car and then drying up. My cooling system is out of warranty since I have over 36,000 miles on it, but I never had problems until after the water pump was replaced (long before 36K miles), at least not with the smell and sloshing. My wife's 200 does none of this, so something isn't right for sure. Guess I i will look under the car tonight to see if I can see any visible evidence of leakage.
