Engine Cooling problem
2002 Buick Rendezvous 6 cyl All Wheel Drive Automatic 99000 miles

My car keeps overheating and the fans are not turning on. We replaced the relays and the Temperature Sensor which did not help. When we disconnect the Temp. Sensor the fans engage. Any ideas please?

There are two sensors, one for the computer one for the fan. Check your radiator with the engine shut off to see if it's the same temp all accross it. If you fel any cold or cool spots it needs to be replaced. Make sure the fans don't kick on while doing this.
