- Secure with Jack Stands: Immediately place two jack stands under designated frame points near the jack. Lower the vehicle slowly onto the jack stands, ensuring it’s stable.
- Remove Wheel: Finish removing the lug nuts and take off the front passenger wheel. This provides better access to the alternator area.
- Underbody Shield: You may need to remove a plastic splash shield or underbody panel to fully expose the alternator. These are typically held in place by a few plastic clips or small bolts.
Double-check that your vehicle is absolutely stable on the jack stands before proceeding.
Step-by-Step 2006 Ford Fusion Alternator Removal
Now that your vehicle is prepped and secure, it’s time for the actual 2006 Ford Fusion alternator removal.
Follow these steps carefully to avoid damaging surrounding components.
Relieving Serpentine Belt Tension
The serpentine belt drives the alternator, so it must be loosened and removed.
Locate the belt tensioner, which is usually spring-loaded.
- Locate Tensioner: Identify the automatic belt tensioner. On the 2.3L engine, it’s typically below the power steering pump. On the V6, it’s usually on the front of the engine.
- Apply Tensioner Tool: Fit your serpentine belt tool or a long breaker bar with the correct size socket (often 15mm or 18mm) onto the tensioner pulley bolt.
- Rotate and Release: Rotate the tensioner clockwise (or counter-clockwise, depending on the engine) to relieve tension on the belt. Hold it in this position.
- Remove Belt: While holding the tensioner, carefully slip the serpentine belt off the alternator pulley. You can then release the tensioner slowly.
- Route Belt Away: Move the belt out of the way, or remove it entirely if it’s due for replacement. Take a picture or draw a diagram of the belt routing before removal!
A new serpentine belt is a good idea when replacing an alternator, as they often wear out around the same time.
Disconnecting Electrical Connections
The alternator has a main power cable and a connector for the voltage regulator.
Ensure the battery is still disconnected before touching these.
- Main Power Cable: Locate the thick power cable (usually red) connected to the back of the alternator. It’s typically secured with a nut (often 10mm or 13mm). Loosen and remove this nut, then carefully pull the cable off the stud.
- Wiring Harness Connector: Find the plastic wiring harness connector plugged into the side or back of the alternator. Depress the locking tab and pull the connector straight off. Be gentle; these plastic tabs can be brittle.
- Secure Connections: Tuck the disconnected cables and connectors away so they don’t interfere with the alternator removal.
Inspect the terminals for corrosion. Clean any corrosion with a wire brush if necessary.
Unbolting and Extracting the Alternator
The alternator is held in place by several mounting bolts.
These can sometimes be stubborn, especially if they’re rusted.
- Identify Mounting Bolts: There are typically two to three mounting bolts holding the alternator to the engine bracket. These are often 13mm or 15mm.
- Remove Bolts: Using your socket wrench and extensions, loosen and remove all mounting bolts. A bit of penetrating oil can help with stubborn bolts. Keep track of which bolt goes where, as they might be different lengths.
- Maneuver Alternator: Once all bolts are out, the alternator might still be snug in its mounting bracket. Gently rock it back and forth, or use a pry bar to carefully lever it out of its position. Be careful not to damage other components.
- Extract Alternator: Carefully maneuver the old alternator out from the engine bay. On the 2006 Ford Fusion, this usually involves rotating it slightly and pulling it through the gap where the wheel well was. It might be a tight fit.
Take note of how the alternator was oriented and removed, as this will help during installation.
Installing Your New Alternator and Reassembly
With the old unit out, installing the new alternator is essentially the reverse of removal.
Pay close attention to connections and belt routing.
Fitting the Replacement Unit
Ensure your new alternator matches the old one in terms of mounting points and electrical connections.
Sometimes, a slight difference can cause major headaches.
- Position New Alternator: Carefully maneuver the new alternator into its mounting location, aligning the bolt holes.
- Install Mounting Bolts: Insert the mounting bolts and hand-tighten them first. Once all bolts are in, snug them down with your wrench.
- Torque Bolts: Consult your service manual for the correct torque specifications for the alternator mounting bolts. Use your torque wrench to tighten them to spec. This prevents overtightening and potential damage, or undertightening and loosening.
Double-check that the alternator is seated firmly and doesn’t wiggle.
Reconnecting Wiring and Belt
This step brings power back to your new alternator.
Ensure all connections are clean and secure.
- Wiring Harness: Reconnect the plastic wiring harness connector, ensuring it clicks securely into place.
- Main Power Cable: Place the thick power cable back onto the alternator’s stud. Reinstall and tighten the nut. Ensure the connection is snug but don’t overtighten, which can strip the stud.
- Reroute Serpentine Belt: Refer to your diagram or picture of the belt routing. Carefully route the serpentine belt around all pulleys, leaving the alternator pulley last.
- Tension Belt: Use your serpentine belt tool or breaker bar to rotate the tensioner again. Slip the belt over the alternator pulley. Slowly release the tensioner, ensuring the belt is seated correctly on all grooves.
Visually inspect the entire belt path to confirm it’s correctly aligned on every pulley.
Final Checks Before Starting
Before you even think about starting the engine, perform these crucial checks.
They can prevent immediate issues or further damage.
- Double-Check All Connections: Ensure all electrical connections to the alternator are tight and secure.
- Tool Check: Make sure no tools or rags are left in the engine bay.
- Reinstall Splash Shield/Wheel: Reattach any removed splash shields and reinstall the front passenger wheel.
- Lower Vehicle: Carefully raise the vehicle with the jack, remove the jack stands, and then fully lower the car to the ground. Tighten the lug nuts to the manufacturer’s specified torque.
- Reconnect Battery: Reconnect the positive (+) battery cable first, then the negative (-) cable. Ensure terminals are clean and tight.
A quick once-over can catch simple mistakes before they become bigger problems.
