Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Possibly a small pry bar (use cautiously!)
* Gloves
* Shop rags
Procedure (General Steps - Verify with your repair manual):
1. Disconnect the Battery: This is crucial to prevent accidental shorts and injury. Disconnect the negative (-) terminal first.
2. Drain Cooling System (Optional but Recommended): This makes the job much easier and cleaner. Consult your manual for the proper draining procedure.
3. Access the Fan and Shroud: You'll likely need to access the shroud from the front of the vehicle, possibly after removing some under-hood components for better visibility (this is highly dependent on your engine and model). Refer to your repair manual for specific instructions on accessing the area.
4. Locate and Disconnect Fan Wiring: The electric cooling fan motor will have wiring harness connected to it. Carefully disconnect the connector.
5. Remove Fan (if necessary): Some shrouds might come off without removing the fan itself, but others may require fan removal first. Look for bolts or other fasteners securing the fan to the shroud or radiator. If the fan is attached to the shroud, it is typically held in place with bolts.
6. Remove Shroud: This is the most variable part. The shroud likely has fasteners holding it to the radiator and/or engine. These are usually bolts or clips. Carefully inspect the shroud and identify these fasteners.
* Bolts: Use the appropriate socket to remove these.
* Clips: Some clips might require gentle prying with a small flat-head screwdriver or plastic pry tool. Be very careful not to break the clips.
7. Inspect the Shroud and Radiator: Check for any damage to the shroud or radiator during removal.
8. Reassembly: Reassembly is the reverse of the removal process. Ensure all fasteners are tightened securely. Refill the cooling system if you drained it.
Important Considerations:
* Coolant: The cooling system will contain hot coolant. Allow it to cool completely before working on the system.
* Sharp Edges: Be cautious of sharp edges on the shroud and radiator fins. Wear gloves to protect your hands.
* Repair Manual: This is the most critical step. A repair manual specific to your 1991 Lincoln Town Car will show you exactly where the fasteners are located and the proper sequence of removal. Attempting this without one increases the risk of damage.
Remember, this is a general guide. Improperly removing or reinstalling the fan shroud can lead to damage to the cooling system or injury. If you are not comfortable performing this repair yourself, take your vehicle to a qualified mechanic.
