Engine Cooling problem
2002 Buick Rendezvous 6 cyl All Wheel Drive Automatic 110000 miles
my wife has a buick rendezvous. I few weeks ago she called me and told me that her engine overheated. So we took it to a shop who looked at it and said it had a blow head gasket and also needed a lower intake gasket. Wanting 900 bucks to fix it I decided to get a second opinion. The other guy that looked at the car said that he could not find any leaks anywhere and thought that the thermostat was sticking and I could use a coolant flush. So all new coolant and thermostat and I drove it a halfhour home and it was fine. The next morning my wife goes to work and she has the same overheating problem. I noticed that there were alot of gunk in the resouvoir and in the radiator cap. I flushed the radiator 3 times now. Each time it seems fine for awhyle the heater is blowing hot and then it does the same overheating crap again and the heat gets cold. I think something is getting clogged in the heater core but dont know how to fix it. Anybody got any ideas on what to do?
