Why pay $1500.00 for a cooling fan? Try the many on-line auto parts sources, such as; www.RockAuto.com or www.autopartswarehouse.com for the replacement parts. For example, they (Rock Auto) list the radiator fan motor from around $267.00 for your vehicle.

Jimm 4/24/2012I'm not sure what you'll need. First, test the relay, the temperature switch, and the associated wiring and connections. Once these cheaper items are ruled out, or repaired - then test the fan motor itself. Each of these items that control the fan operation are separate from the cooling fan assembly itself - and can be replaced separately - as needed.

Don't use the suggested 'manual' method - stick with the automatic fan control based on the engine and cooling system temperature - as orignally designed. You may forget one time to turn on the fan while in traffic - there goes the engine - for the sake of saving the few dollars to rig up a fan control - you may end up costing thousands.
