Q: 04 aviator started over heating 2 months after thermostat replaced and within seconds damaged radiator need to know possible cause

asked by on March 10, 2018

04 aviator was overheating every time it was driven more than a mile but not while idling. Replaced the thermostat and purged the system of air and it drove amazing for 2 months. Then all at once overheated rapidly and damaged the radiator, two small holes on the top front of it. I would greatly appreciate of someone could suggest possible causes. I am about to buy a new radiator and water pump but if it's a much bigger issue I wouldn't want to waste the money. I am a medic in Oklahoma and have a ridiculous schedule so going to a regular mechanic to have it checked isnt an easy thing to do.

My car has 200000 miles.
My car has an automatic transmission.
