jndnaps Posted February 5, 2015 Report Share Posted February 5, 2015 For years now I seem to smell a very slight smell of antifreeze in my 96 Deville when I run the heat or when the A/C is on low. I also see a slight film of some slightly slimy stuff on the woodgrain on the dash. The dust sticks to it and when I wipe it off with my finger it seems to feel a little slimy or oily, but doesn't really smell like antifreeze. I was thinking I may have a pin hole leak in the heater core or the hose. If the heater core needs to be replaced, how is that done in a 96 Deville? Does the dash have to come out, or can it be done by removing the glove box and lower panel? I have nothing leaking in the car or any noticeable stains in the carpet on the passenger side. I just get the slight smell and film and it takes many months to actually notice it.. Quote Link to comment Share on other sites More sharing options...
Cadillac Jim Posted February 6, 2015 Report Share Posted February 6, 2015 The 1997 FSM, page 1B-27, remove the heater core has these steps: REMOVE OR DISCONNECT Negative battery cable. Partially drain coolant. Instrument panel compartment [glove compartment]. Right sound insulator. Heater and A/C programmer. Heater core cover. Inlet and outlet heater hoses from heater core. Heater retaining screws. Heater core.
