Fan stopped working on my 96' Dodge Neon causing it to overheat every time I came to a stop or was moving too slow for the wind to cool the engine. Huge pain in the ass if you don't get it fixed soon. If you have this problem, replace the Coolant temp sensor located in the cylinder head on the driver side. Very easy to find and replace. All it takes is a deep socket, socket wrench and a drain pan to catch the fluid released from the head. Sensor is located under a couple hoses, but you should not need to remove them. Simply reach under the hoses, disconnect the connector from the sensor, get the socket onto the bolt holding the sensor into the head, connect the socket wrench to the socket, and loosen until removed. Then, install the new sensor, re-connect the connection to the new sensor, remove the radiator cap (as long as the engine is cool) and fill the system with 50/50 mix (not just water), put the radiator cap back on and that's that. MAKE SURE TO DISCONNECT THE BATTERY PRIOR TO CHANGING RELAY, FUSE AND SENSOR!!!!
It is not worth the possible problems to save yourself 20 seconds that it takes to disconnect the terminals.
