Is smoke coming from exhaust or engine compartment? If is from exhaust then yes, I am certain about the smoke.. White smoke from exhaust indicates coolant being burnt (unless it is just condensation, not actual smoke). Dark grey or black smoke means too much fuel to system or oil being burnt.. In this case it is coolant (or condensation, so check your coolant level).
Next thing to test will be the temperature sensor. Sometimes when they fail it wil never turn on the fan. Also test the fan to make sure it actually works. You can usally test the fan motor to see if it works by turning the A/C on, which wil automatically turn the fans on by default. The coolant temperature sensor is located on top left rear of engine, pictured below.
