help!!!
You shouldn't need to be worrying about your overflow tank going down. If it's at the same spot, in between the min and max marks indicated on the overflow tank, you're fine. As long as no loss of coolant continues, leave as is, don't worry about "filling" up.
If it's leaking out anywhere, then each time it cools down it sucks more coolant out of the overflow tank. If your cap wasn't working properly, your radiator could've been half empty...
So you still gotta find the leak. Look for crusty deposits around the hoses. Pull your spark plugs. If your headgasket is leaking coolant into a cylinder, that plug will look really clean.
