How many miles, was the expansion tank ever replaced? You will see white powder residue which is where the coolant dried up. If you have over 60K miles, the expansion tank probably needs replacing. Check your hoses and water pump for weeping. The O-ring on the level sensor in the bottom hose sometimes leaks. Also check the radiator. You should do a complete cooling overhaul.
