Is it possible for your truck to 'burp' itself? Let me explain, my truck, an 06 GMC Sierra with 5.3, had a leak in the radiator and was overheating,so I changed it. OK it's still overheating, so then I changed out the water pump,still overheating. Changed the thermostat and I cleaned out the heater core, still overheating! so I did a compression test on it and it failed. you know the blue turned green. Head gasket. so I parked it until I can afford to fix it. so I parked it until I could afford to fix it. it was about 2 months I guess, that she sat. maybe that's that And I hopped in it today, she fired right up. I was taking her to the garage, expecting it to over heat before i hit the end of my street and ive been driving her for 2 days and no overheating. Hmmmm? Please explain.
