You will have a viscous fan clutch, and when they are engaged cause the fan to really howl. From the description you gave, it sounds to me like the fan clutch has gone faulty and locked up. See if you can spin the fan by hand with a cool or cold engine, there will be some resistance but not much. If it's very hard to spin, or won't spin at all, you need a new fan clutch assy. Also, you'll need a big wrench and pulley holding tool to get the fan off as they're threaded onto the water pump shaft. Let me know what you find out. By the way, napaonline.com lists them for about $76.00
