i just bought this 1995 cad deville 4.9 and at first smoke was coming in from the firewall. i later put coolant in the radiater because it was empty and it stopped smoking. now the coolent is running in on the passenger side floor from behind the firewall can anyone help me?:frown:

Sounds like the heater core is leaking.

The heater core isn't very expensive, but it's kind of a pain to change! I changed the one in my '94 Deville last year, and I don't want to do it again anytime soon!
