car started running hot yesterday and today the temp was 220 and the fans were not on..there are no cels on, where do i start to diagnose this problem?
okay another update, while driving with ac on the fans turn on, but the temp still gets to 215 and pressure relief opens. could the tstat not be opening? i also noticed the uppr rad hose swells more than usual do to the increased pressure, could this also be a sign of the tstat?
