I have a 2004 H2 and I am getting overheating indications on the driver corntrol center and the heat gauge. It was fine when I drove it home and the next morning at 2am when I started for work it overheated with 5 miles of home. I have changed the thermostat, the water pump, the fan clutch and the coolant cap and it still overheats. I am desparate. Any ideas?
