Engine Cooling problem
2003 Chevy Cavalier 4 cyl Front Wheel Drive Automatic 140000 miles
i recently started overheating in stop and go traffic. I noticed that thought the engine was very hot and the AC was on but the fan was not turning. I checked the voltage at the fan plug while the engine was running (AC on) and I got just over 13 Volts so I assumed the fan motor was bad and I replaced it. Immediately after I installed the new fan everything seemed to be back to normal, (engine hot or AC on, fan running). After several days I am getting higher than normal engine temp again. Again I checked fan with ac on and it is no longer turning. When I replaced the fan I was very careful not to over torque the bolt holding the fan to the fan motor shaft. I am wondering if there is another problem with the system that is causing my fan motor to go out. Is the 13V to high? I spun the fan with my hand and it seems to turn freely.
Thanks for your help.
