问：我的车从中冒出白烟。我今天将冷却液放进去，因为它很低。为什么有烟雾

我的车遇到了一些问题。一方面，每次我获得汽油，然后尝试启动我的汽车，就不起作用。我需要尝试在它实际工作之前重新开始。然后它在终于走之前发抖。我去了Autozone，但他们还不清楚。他们说了一些关于蒸发系统的事情。现在，我还有另一个问题，白烟来自我的引擎盖。我的冷却液水平确实如此，所以我得到了更多。Before that though, my I needed to change my oil but I didn’t for like 4 months (I know. Terrible car owner) I got it change though and everything seemed okay but then like a month later, my engine would randomly almost overheat and I didn’t know why. Come to find out that my all of my coolant was gone so I got it I got some more. After just a day, I had to use the whole bottle because my car had ate up all of the coolant. There was still some in my car though so I left it alone for a little while. I put some more in today then white smoke came. Please help.
