Recently my 1999 Grand Jeep Cherokee Laredo 4WD overheated and the radiator broke. After changing the radiator we found out that this was caused by a malfunctioning radiator fan. The mechanic stated it could be the relay so I decided to make the change. Thanks to this website I found the relay under the left front light and was able to replace this. However, the fan still did not work properly although the fan seemed to turn very slowly without cooling down the engine.
I have driven the car to work as the air flow seems to help keep the car cool. However, today the car overheated thanks to traffic and little car movement. Fortunately, the radiator did not break but the upper hose did. I do not know what the problem could be
? What moves the fan? Is it a belt or an electric motor? If it is the motor, how can I check if this works? Could it be the fan itself?
