General Steps (May Vary):
1. Disconnect the Battery: This is crucial to prevent electrical shocks. Disconnect the negative (-) terminal first.
2. Access the Fans: This usually involves removing some components in front of the radiator. This might include:
* Shroud Removal: The fans are often mounted within a plastic shroud. You'll likely need to remove screws or clips holding the shroud to the radiator and/or other components.
* Removing other components: You may need to remove the air conditioning condenser, some plastic trim pieces, or other components to get sufficient access. Your repair manual will detail this.
* Accessing the Fan Motor Connectors: Locate the electrical connectors for each fan motor. Carefully unplug them.
3. Remove the Fans: Once the shroud (if applicable) is off, you'll usually need to remove screws or bolts holding the fan motors to the radiator or shroud. These may be difficult to reach, requiring specialized tools or extensions. Sometimes, the fan blades themselves have to be removed first (often after removing a center nut).
4. Install the New Fans: Follow the removal steps in reverse order. Ensure that the new fans are correctly oriented and seated. Carefully reattach all screws and bolts, making sure they are tightened securely.
5. Reconnect the Electrical Connectors: Double-check that all connectors are securely plugged in.
6. Reassemble: Replace any components you removed to gain access to the fans. Make sure everything is correctly reconnected.
7. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
8. Test the Fans: Turn the ignition key to the "ON" position (without starting the engine) and check if the cooling fans operate correctly. You might need to use a diagnostic tool to activate the fans if they're not automatically engaging. Some Windstars have high and low speed settings that may be tested through the diagnostic system.
Important Considerations:
* Cooling System Pressure: Ensure the cooling system is not under pressure before beginning. Allow the engine to cool completely.
* Electrical Connections: Be very careful when disconnecting and reconnecting electrical connectors. Take photos to help with reassembly.
* Specific Year and Engine: The exact procedures will differ based on your Windstar's year and engine type. Use a repair manual.
* Tools: You'll likely need various sockets, wrenches, screwdrivers, and possibly a ratchet and extensions to reach difficult-to-access fasteners.
* Safety: Always wear safety glasses to protect your eyes from debris.
This is a complex repair and should only be attempted if you have experience with automotive repairs. If you are unsure about any step, consult a qualified mechanic. Improperly installed cooling fans can lead to overheating and engine damage.
