i have a 2007 pontiac grand prix that has only 63??? miles.. my overheating problem happened about a month or so after i had the tranny and coolant flushed, i replaced the thermostat and my car still blowing hot air out the vents and, its engine is getting really hot and steams after the temp gauge gets between a quarter to half way to max .. is this a common relay problem? or more serious?
