That's what I thought also. There was a leak earlier this summer but we never could find it and it just quit leaking. Never did see any white sweet smelling smoke (thank god) and it hasn't been flushed lately. I'll pull it into the shop again and check it out but I think it must have leaked out enough then and not any more. Weird thing is it was maybe a gallon low, I wouldn't think that was low enough to cause the heat to work intermittently.Well, that's some good news. The bad news is that you really need to find out where that coolant went. Could be anything from a bad head gasket to a leaking hose, radiator, overflow tank, etc. Is there any noticeable signs of coolant anywhere? Any white smoke lately with a sweet smell to it? Easiest is to do a visual check. I would start with checking the hoses, heater core lines, bypass hose, t-stat gasket, radiator tanks for seepage, overflow tank for cracks or a bad hose, etc. If you can't find any visible external leaks, then it's time to start looking for internal leaks.
Has the cooling system been flushed recently? An improper fill could also pose some of the same symptoms if there was air trapped in the system.
Why backflush and what's wrong w/ my head gasket?Backflush that crap out of your radiator unless you really want to kill your engine.
Take a GOOD look at a head gasket if you want to see why.
And replace that radiator.
Stop Leak will plug small leaks in radiators and also small water passages in your engine. Thus stopping proper coolant flow.Why backflush and what's wrong w/ my head gasket?

Not your head gasket, at any head gasket. You will see the small holes where coolant flows from the block to the head. Stop Leak will plug or restrict these passages. Less coolant flow = hotter head = CRACKed or WARPed head.
Flush it and replace that bad radiator.
I agree that's the best solution. My days of stop leak occured in college. With my lack of funds, a $1.99 tube of dust looked pretty good over a $100 radiator.My advice would be to replace the radiator now. They're not that expensive and your cooling system will thank you.
