I have been trying to chase down a coolant leak problem and noticed that there is a drip coming down what appears to be a plastic flange under the expansion tank. Could the tank be cracked? Is there an easy way to check this? Could this be the reason that the coolant level light comes on when the engine is stopped and then reappears only to disappear when you start driving. Any help would be appreciated.
