Hey yall , back for help with a problem. So the other day my outlet heater hose just decided to burst. I got someone to fix the hose for me but it was with a different hose than the one that was originally on the car . Some how he made it work . He ended up putting the Regular Green coolant in the car instead of the Dex-Cool orangish pink coolant because it wasnt any coolant left in the car seeing as though the hose exploded . He got all the air out of the system and we drove it around to test it, however the engine temp was fluctuating way colder than normal operating temp. I replaced the thermostat in January of this year but unsure of if the coolant temp sensors has been changed. Today while driving for about 20 mins i noticed that the A/C off due to high engine temp message popped up and the temperature gauge stopped working . Also the check engine light popped up . I live in Guam and most auto places here are closed on Sunday so i couldnt take it so see what code was being thrown. . Could the issue be because he put the wrong coolant in my car or is it possible that a 2 1/2 month old Thermostat has gone bad . Im lost here and need all the help i can get . Thanks in Advance!!
