Hey I just bought a 2017 Chevy sonic LT RS 1.4 turbo. I’ve got a coolant leak coming from the lower passenger side of the radiator I put cold distilled water into it and started it with no leakage but once it get hot again it started leaking. I put about a gallon and a half into it and drove it home, about three miles or so. and it leaked out about half a gallon but the temp light didn’t come on this time. any help would be appreciated as I bought the car today and have no idea what I’m looking at when I open the hood.
