My truck started smoking by one of the hoses next to the radiator?

The coolant is full, and the transmission fluid was recently flushed along with an oil change.|||The hose might be leaking, change it|||Try squeezing the hose, if it feels soft, replace it before it busts. if you drain the antifreeze out to replace it,Put in new antifreeze,(Because it%26#039;s not good to put what they call contaminated antifreeze back into an engine) Check to make sure that your clamps are tight enough. Good Luck. (And try not to get antifreeze on the paintjob,it might mess up your paint
