Loosing Coolant

[siether]

I was wondering if anyone else has or had this problem. Ever since i got my alero last june I've notice that when it comes time to change the oil i've lost about 1 to 1.5 litres of coolant out of my resivoir. It's not leaking into the oil and not onto the ground. Some people said it's normal that some of it evaporates, I could understand in the summer, but I still loose coolant in the winter. My Alero is an 01' with 42000KM. Can anybody shed some light on this for me. Should I be really concerned or not?

crack open a raw egg and dump it in your radiator. If you dont belive me, ask the Myth Busters.

Mine was losing coolant and it turned out that the O ring on the thermastat cover was leaking thats it 175 dollar labor for a 99 cent part heheheheheh

the only explanation i could have is that your engine gets hot and it boils or evaporates out, it wont evaporate cause its summer but because of high engine heat.
