We've been noticing a light blue fluid dripping on the garage floor. It's coming from the engine bay, more towards the drivers side.
Any ideas? Concerns?

 

Coolant, check your coolant expantion recepticle for leaks

 

I just brought my 2005 MCS in for a similar problem. There were 3 things wrong: 1. Valve cover gasket - this is the leak I was seeing. 2. Thermostat housing coolant leak. This was dripping and evaporating immediately; my SA said it was something that would have probably gone undetected (by me, anyway) until it was too late and I overheated since the leak was not actually hitting the floor. 3. The third leak was the bad motor mount on the passenger side.

All 3 leaks were fixed under warranty.
