Today I was cleaning up my car after I got it back from a shop that was removing my turbo. They told me the car was running fine but was smoking a little, I went to pick it up yesterday, drove it 10minutes to my house, was in a bit of a hurry so once I got there, I parked the car got out and left until today. After the cleaning I started up my car to let it run for a bit. After a couple minutes of idle, there was white smoke coming from under the coolant resivoir/battery. I couldn't really see much as it was already dark. I was able to get a flash light to look around and noticed a sweet coolant smell as well as seeing a bit of coolant on the plastic piece on the bottom of the car. My coolant light did not come on and I could see the coolant level did not appear low. Any ideas?

 

Sounds like a coolant leak. Check them hoses! Yes they are on tight buy they might be bad.
Or *Caution!* check your battery. Could be leaking. This was reported once.

 

Could be a coolant leak, Or possible they had to remove some cooling hoses out of the way, some may have stayed trapped under there. When you leave the car on it gets hot and might be heating it to smell. This is one option.

Another would be to check your hoses and clamps cause it could be a coolant leak. I would remove anything in your way so you can better see. Fill the coolant to the right level. With the car being cold of course. Start the car and let it build up pressure. Give a good squeeze to the top hose and check for any leaks. Care full cause it will be hot. Under pressure you would be able to see the leak.
A much easier way is to buy a coolant pressure tester and put about 16psi on the guage, check for a leak. You can do this while the car is cold and coolant is cold.
