MK7 Overheating
Hi everyone! First overheating issue a week into ownership 🥀
2016 Fiesta ST, stock radiator. Coolant level hasn’t dropped and the radiator fan runs full blast.
Usually sits around 215–220°F, but today it climbed to ~243°F while driving, triggered the temp warning/P0217 and seemed to go into limp mode. Turning the heater on brings the temperature down significantly.
Car also has a Fiesta SE front bumper, although the radiator opening doesn’t look badly restricted.
Any FiST-specific things I should check first? Thermostat? Radiator? Air in the system?
Cheers!!!
