Driving down the highway tonight, had the belt completely blow. Pulled over after I noticed the battery light and check gauge light turn on in the dash. Noticed then the fan wasn't spinning and the temp gauge was all the way over to the red. Limped it home approx 1 mile from where I noticed the temp gauge heating up and had pulled over, hoping I didn't crack a head from overheating. When I pulled over it cooled down a little bit, but was still near the red. Do you think driving it a mile with neither the water pump or fan blowing would cause a head to crack? No coolant leaked out, it's a Vortec head, and it was 29 degrees out tonight.
