I am new to this, Her is my problem. My sister owns a 1991 DeVille that she got from my mother, the Caddy is in pretty good shape but has a leek in the heater core. i remember in the old days you could bypass the the heater core by connecting the to heater core hose to the return hose, untill you had time and money to fix the problem. Is this still possible?
