I own an '88 Corolla. I appear to be losing coolant in the radiator, and the overflow is steaming, in a milky white uh...well, steam. I can smell a faint sweet scent, which indicates antifreeze. When I looked at the engine when I first noticed it, I could hear a gurgling in the overflow tank and the steam was coming directly from it. It's causing my engine to overheat rather rapidly (by five-ten minutes of driving, the needle is up at the red). Does anyone know what could be causing this? I just filled the radiator a couple weeks ago, and just tonight it was below the line, so I think there might be some kind of leak, but I don't see a noticable drip. Any help would be appreciated.
