After heading home from taking my son to the er, my temp gauge started to rise fast to the red lines while I was going down the street. I quickly pulled over, put it in park and shut my engine off. I got out out of the car and looked under neath. Coolant was pouring all over the ground under the engine. Obviously couldn't drive so I had to call the husband to pick us up and a tow truck. Took the van to two different garages and they both said the head gasket blew. I have found that GM knows about this problem and many have complained but yet not one recall on this issue. I have even seen this issue in the service note due to plastic parts. Garages are asking 15 hundred for repair!!!

Van over heated after replacing water pump and thermostat. Dexcool was required by GM for warranty car was flushed out and dexcool was replaced. One week later van over heated again, was told it was an air bubble in heating system. Bleed out system using a vacuum pump and pulled out all the air in the system. This worked for about 3 months. Problem returned again in spring in 3/6/2012 over heated again drivingbat highway speeds 25 miles from starting point. Found air in system again. Had water pump, thermostat, hoses and coolant all replaced again. Problem is still occurring. Dexcool destroyed the head gasket in the motor. Needs to be replaced. This is a common problem I have found from new repair shop they work on at least 2 a week. GM has hidden this from the public needs to be a full recall on head gaskets. At no cost to owners. This repair will cost about $1500 to $2000 depending on the repair shop I have contacted. When car was under warranty nothing was said, now they say it's the head gaskets at the GM dealerships.
