1996 Cadillac Seville STS Question: Coolant Leak
I would not jump to the conclusion that it is a heater core leak without first doing a cooling system pressure check. The way an automotive shop would locate the leak is by removing the radiator car and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. - patrick mannion
Empty your coolant resavoir with a turkey baster , disassemble ,check if cracked , specially on the connection with the hose. - Visitor
