My car is leaking anti freeze smokes a little but coolant level in vech doesnt show im over heating, I just repaired an over heating problem but mechanic with out even looking at it says its a total different repair. I dont no anything about cars so im not sure if he just said that to get more money or what the problem is
Have the system pressure tested. This will expose any external leaks. If the vehicle is blowing out white smoke from the tail pipe then you have a combustion leak. Just throwing that out there cause you said it smokes.
