My 2005 Buick Rendezvous ---heads were leveled and complete valve job done with new water pump, thermostat, relay belt,bypass hose, upper radiator hose, and complete coolant flush. My car keeps running hot. Please help!.
We found out that we had a problem with my wife's vehicle. Initially, the vehicle was stationary. I took it to get an oil change and was asked to come into the shop to be shown that the antifreeze was like yogurt in the reservoir. We were told that we needed a coolant flush. This led to being told that we needed a new radiator; bypass hose; and last but not least, head gasket job amounting to approximately 1600. 00. We were told that there was no open recall but yet there was litigation going on regarding dex-cool antifreeze and that it was causing all of the problems that were and are having with this vehicle.
I took my car to the local gas station about 3 minutes from my house. I went in came back and out and before I was even halfway home my car started to overheat. I hadn't even driven half a mile. The thermostat and the coolant temperature sensor have been replaced and the radiator flushed. There was all sorts of brown gunk in the line but the issue still is not resolved. The heat only works occasionally after this and the car still will run hot and then drop back down to a normal temperature all within 2 minutes. No one is sure of what is going on with it. The cause cannot be found at this point.
