Sunfire losing a little coolant..

The car is a 03 sunfire with the ecotec engine.

The car is losing about a couple quarts of coolant every month, I can’t figure out where it is leaking from.

The car has new radiator hoses, and the heater hoses are in good shape. It doesn’t appear to be leaking from anywhere. I put on a new overflow bottle cap.

There is no coolant in the oil or anything like that. The radiator is original and I can’t see the thing leaking from anywhere.

blowing white smoke? headgasket. Here’s a little tip for that too. Pull the oil cap and see if you have a hazy tan sludge buildup underneath the cap.

May need to be pressure tested in order to find the leak if there is an external leak.
