Just noticed today that my coolant is low. Could it be age? The hoses look ok as I don't see any leaking. Maybe a Head gasket issue? which I don't think it is. She ran fine going to Disney and back. It's a 2010 LT 2.2 built in Sept. 09 with nearly 40k. For now i'm looking at topping it off with 50/50 dex.

I recently topped it off with GM approved 50/50 dexcool. so far, Car's been running fine since. Will this cause any issues afterwards? If so I'm planning on having it flushed soon.
