I canot drive over 2 miles before it starts to over heats
the coolent leaks after I put 4 cups of coolent into the
overflow tank on 1997 Cadillac Catera
DO NOT DRIVE THIS CAR ANYMORE. Until the coolant leak is found. Coolant does not evaporate. You have a leak. Hopefully you haven't overheated to much and allready done engine damage.
