Why is my car smoking from under the hood?

I have a 2008 mustang. It was smoking a few weeks ago and I took it to the shop they said it needed a new radiator so I paid to have that replaced as well as all the hoses and what not. Now it’s smoking again. It never overheats on the temp gauge but it’s smokes. Why could this be when I just replaced the radiator? They said that was the issue and it was fine for a few weeks.

    Radiators do not smoke, but they can steam when there's a coolant leak. If your car is *smoking*, it probably has an oil leak burning on the exhaust. If there is still steam coming off the engine, the mechanic may not have fixed all the leaks, or he left a hole loose to leak more.

    A hose clamp may be loose. Take it back to the mechanic that replaced the radiator for him to inspect his work. No charge!

    The car is leaking coolant again.  That is all there is to it.  Get the cooling system pressure tested to find the leak.
