There is an iPhone app called FordPass. If you get the app pretending it’s your car and input the vin number you can get the service records for work done at Ford dealers. Carfax is also useful for researching the service records done at shops that report to carfax, many do not report. If the work was done by a shade tree guy you won’t find the record and likely you wouldn’t want the car anyway. He probably used aftermarket parts. You want the OEM parts. Very complicated job for a one off mechanic.
If the service records show the car was service regularly you are probably okay and getting a good price because of the negativity surrounding the water pump failure issue. A 2010 has the first generation timing chain which is a negative but since it’s normally aspirated and not turbocharged, the engine is probably going to outlast the cars underside because it was a salt belt car.
Frankly, I’d be more worried about salt induced rust and hidden corrosion if it’s a Chicago area car.
