Smoke

We have a 2000 ford escort ZX2, it has about 110,000 miles on it and we're unsure of the engine size, we just had the radiator replaced and the transmission worked on within the last month or so. Now it has lost all the coolant, which we replaced, but there's smoke coming from the left section (if you're facing the front of the car) close to where the belts are on that side. There's a strong smell also. Temperatures aren't going up and there's a low key almost hum sound but otherwise it doesn't seem like there's anything going on with it. We're afraid to drive it even to a repair shop because we don't want it blowing something out or catching fire or anything. Please help.
