Oil, coolant, fuel, condensation (moisture). All can cause white
smoke and they all smell different as well.
If you are familiar with the different scents, carefully smell the
white smoke to identify what the source liquid "might" be.
Once you know the type of smell, you can determine the cause.
With the colder climate ahead, it is common to see white smoke (condensation)
leaving the exhaust pipe. But should go away once the engine has
reached operating temp (unless ambient temp is low enough to keep
the condensation visible).
