Tools You'll Likely Need:
* New serpentine belt: Make absolutely sure you get the correct size and type.
* Socket wrench set: Various sizes to potentially loosen pulleys if needed.
* Wrench: Possibly for some pulley bolts.
* Pliers or a belt tensioner tool: This is CRUCIAL. You'll need something to relieve the tension on the tensioner pulley. Some tensioners use a lever, others require a specialized tool.
* Gloves: To protect your hands.
* Jack and jack stands (optional but recommended): This can provide easier access and stability. Never work under a car supported only by a jack.
Steps:
1. Locate the Tensioner: Identify the tensioner pulley. This is usually a pulley with a spring or arm connected to it that allows for belt tension adjustment. It's often located near the alternator or power steering pump.
2. Access the Belt: You might need to remove some plastic covers or shrouds to access the belt easily.
3. Identify the Route: Before removing the old belt, carefully trace its path around all the pulleys. Take a picture or make a sketch if needed; it's easy to forget the route.
4. Release Tension: This is the hardest part. The method will vary depending on your car's design:
* Lever-type Tensioner: Many cars use a lever-style tensioner. You'll need to find a way to carefully pry or push the lever with a sturdy tool (like a pry bar or a specialized belt tensioner tool) to relieve pressure on the belt. Do this slowly and carefully; the spring is under considerable pressure.
* Mechanical Tensioner: Some systems utilize a ratcheting mechanism; you'll need a special tool to turn it. Check for access points or a specific socket needed.
5. Remove the Old Belt: Once tension is released, the old belt should easily slide off one pulley. Work it off the rest of the pulleys.
6. Install the New Belt: Carefully guide the new belt onto the pulleys, following the route you previously noted. Ensure it sits correctly in all the grooves.
7. Release Tensioner: Slowly and carefully release the tensioner to allow the belt to fully seat.
8. Check for proper routing and tension: Double-check that the belt is correctly routed and that there's good tension. You should not be able to easily twist the belt more than 90 degrees.
9. Reassemble: Replace any covers or shrouds you removed.
10. Reconnect the Battery: Reconnect the negative battery terminal.
11. Test: Start the engine and listen for any squeaking or squealing noises indicating belt slippage or misalignment.
Important Considerations:
* Consult a Repair Manual: A repair manual specific to your 1993 Lincoln Continental is highly recommended. It will provide diagrams and specific instructions.
* Safety First: Always use jack stands and never work under a car supported only by a jack. Wear safety glasses.
* Difficult Access: Access on this vehicle may be tight. Consider using a small flashlight and possibly a mirror to help guide you.
If you're uncomfortable working on your vehicle yourself, it's best to take it to a qualified mechanic. A misaligned or improperly tensioned belt can lead to further damage to your car's components.
