Whisps of sweet smelling smoke /steam is most likely a heater core issue. There is a product on the market called IRON TITE that will plug any leak in a heater core and will not compromise the cooling system by plugging.

You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

depending on how bad, and how long the orginal core leaked, it might just be residue in heater box, and if it got up into the vents, it will take awhile for it to dry out.

if your 83 deville is a coupe like mine then you can access the heater core from under the hood, not the interior of the car. take a look at the blower motor and you'll see that the plastic cover that it is mounted on comes out. under that large plastic cover you'll find the heater core. it takes a while to get all the little screws out, but it's more monotonous than difficult. you'll have to disconnect the blower cables, the temp. sensor and harness, and a few little ground wires and you're there. once you get to the core it's really self explanatory. undo the hoses, replace the core, clean out the piles of pine needles that have accumulated over the years, then put it all back together. if you have the core in hand, then you can replace it in 2 hours if you take your time. hope this helped. let me know if you have any troubles.

Problem is most likely the water pump.Have seen several of these doing this on the 5.4L. Impeller fins were damaged on the ones that I have seen.
