The engine starting running hot while I was in a drive through line. Once I got it back on the road the temperature came back down but I thought I should have it checked out. So I took it to a place that I trust and the first thing they said was that there was Sludge in the radiator. They indicated that they have seen this issue with several cars with the Dex-Cool in the car. After hearing that and knowing the car was still under warranty I took it to the dealership. They said that the sludge was cause by a bad intake gasket. They replaced that and the thermostat as part of the repair. When I asked them if they flushed the radiator and coolant system to get all the sludge out of it they said "NO". The dealership indicated to me that it won't bother anything. That they could flush it out but it wouldn't be covered under the warranty and they would charge me $130 to flush it out. I personally don't see how any amount of sludge in my coolant system can be good and then when searching further on the problem on the internet it appears to be a big issue for a lot of GM vehicles.
