Question about Buick Skylark
The "smoke" you saw was your coolant. The vehicle uses engine coolant piped into the cabin of the car and through a little radiator under the dash for the heater. The blower in your car forces air over this radiator and this heated air is what you feel at the vents.
If you're lucky then one of the hoses has sprung a leak. This is a relatively uncomplicated cheap fix. The other thing that could have happened is that the cabinheater radiator has sprung a leak. If the leak is serious then the heater radiator will need to come out for repair or replacement.
You could try running some radiator stop leak(I've used Wynn's before) through the system and see if it helps. If the leak is on the radiator it might just work. On the pipes it will not be successful. Buy a bottle at your local spare shop/Autozone. Put it in the cooling system(do not open a cooling system with the vehicle hot!) and let the vehicle idle for a while. (Read instructions on the bottle) If it does not work, have the heater radiator removed and repaired.

Your heater core has a leak. The best way to fix this is replacing it with a new one.
Now if you do not need the heater right now, get a hose repai kit from any hardware (it is cheaper than the AutoParts), the kit comes with a nipple and two clamps. The nipple should be of the same inside diameter of your hose 5/8" or 3/4" are the most common sizes.
Under the hood, passenger side firewall, you'll see two hoses held by hose clamps, loosen the clamps and remove the hoses using a twisting motion and pulling at the same side, use the nipple and clamps to join the two hses together. Doing this will bypass the heater core. Once the leftover antifreeze is drained, your leak will disappear,

White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
It is also possible to be a engine problem you should immediate visit a car service.
