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.

My cadillac is not giving me any hot air ,ive replaced the radiator, changed the thermostat, has a new water pump, where do istart to look.


Feel the 2 tubes at the firewall for the heater core. If they are not getting hot, the heater core needs to be flushed out or replaced. I had this problem with a 1990 Cadilac Deville, it was just a plugged up heater core.

Remember to install sealant after flushing out the system to prevent leaks.

How difficult is it to replace the connections to the heater hoses? They broke off trying to disconnect the hoses from the firewall.


Do you mean the pipes that come through the fire wall broke off? Those are part of the heating core. You must replace the heating core.

I just replaced the pulley on my 1997 cadilic deville and now my car is overheating and i have no heat/


Sounds very much like like a water pump or pump belt problem. If there is no coolant circulating (indicated by the overheating), you will have none passing through the heater core of the car.
