As a DIY type mechanic (not a real one) I’ve seen my car close up on me multiple times. When I think over heating I think no water circulation and the thermostat is the cheapest to start with. When it’s closed from my idea is that it prevents the flow to the engine and then the heat starts backing up. Ever see your coolant box piss out and bubble? If no water is on your oil then my guess it’s a clog. Blocked thermostat.
