So I’m buying this car , and the lady says it starts to over heat after 10 mins of driving but says it’s not a big leak but she can’t find it and the engine doesn’t smoke

What is your question?

Like she says, it over heats after 10 mins or more of driving but it doesn’t smoke out of the engine but also says when she stops the car and looks underneath it’s not a big leak like she can’t find it but I need help like do I just buy a whole kit for the intercooler
