Scotty, my mom's 2003 Lincoln Town car with 176,153 miles on it overheated the OBD2 codes are p1229 for both Banks and p1285. Coolant was bubbling out of the radiator cap, but I didn't see leaks anywhere else. No smoke.
What do you think is wrong with it? Please help.

P1229: Check the Intercooler Pump. You might have to replace that or the wiring is bad. https://www.engine-codes.com/p1229_lincoln.html
P1285: Check the Cylinder Head Temperature Sensor. It's either gone bad or the wiring is faulty. https://www.autocodes.com/p1285_lincoln.html

Don't forget to check traditional causes of overheating such as thermostat stuck closed or clogged radiator.

If it's bubbling out of the radiator cap, you have a bad thermostat and a bad radiator cap.
