98 caddy deville nothstar v8 how to replace heater coil have no heat and I'm loosing water somewhere


the heater core in a 1998 Cadillac is very tricky to replace.
start with getting a pressure test to determine where the exact location of the leak is, it may not be the heater core.
if you do decide to pull the dash apart to change the core make sure the battery is disconnected for at least an hour to allow the airbag system to discharge.

Follow the top radiator hose to the engine. Remove that end of the hose and then remove the thing the hose connects to. The thermostat is behind that.
