We bought this car from someone that needed a larger car...They only ran it short distances to make sure it still ran..........However while driving it home it over heated and the heat light and oil light came on and it stalled.......We changed thermostat hoping it was just stuck and it was bad..But we didn't use sealer and it leaks there now...And not sure if thats the only problem........When we first got home with it and ( I know) you rnts supposed to open radiator cap but the son did and at the top of the radiator on passenger side there was steam...Does this mean anything..............we also change radiator cap......because it broke
