my del sol is turning on, but as soon as it does a big cloud of white smoke comes out from the tailpipe and it does that for about 15min, after that it still does it but in a less quantity. Please let me know.

 

From the place you live, of course you are getting white smoke! Because of the cold weather duh! You should've searched "White Smoke" and i got 25 results about it. Dont worry about it, Unless your motor has been running like crap and that means coolant is getting in your oil. Good luck Btw explain what car, model, year, blah blah blah info next time.
