Hey, new to the forum as it's my wife who owns our 2012 Journey with a 2.4 l engine but I have an issue I could really use some help with concerning the engine overheating. Originally I found the port where the heater core line runs into the coolant line was broken so I replaced that and refilled the coolant. However the engine still overheats but now when it hits 280 degrees the alarm pining stops and the display on the driver's console shifts to a thermometer showing <100 and seems to run ok but had a warning light that looks like ) lighting bold ( . I usually work on older engines so this is all new to me. My next inclination is to replace the thermostat but it seem there are 2 on this engine. Yes there is a check engine light on and when it is overheating there is the red temp indicator light . Any help at all would be greatly appreciated.
