Smelled coolant and saw smoke coming from under the hood. First visit, they said my radiator was cracked. They repaired that, drove the car home and parked it. The next day, my car smelled like coolant again and smoke still coming out. They replaced the thermostat, problem still not fixed. The third visit, they told me it was a y pipe underneath that is made of plastic and the leak was coming from there. They said that was the original source of the leak and probably caused the crack in the radiator. It was fixed for a year then the same piece had to be fixed a year later.
