Tools You'll Likely Need:
* Wrench set (metric): Various sizes, including those suitable for the alternator's mounting bolts, the battery terminal bolts, and potentially the pulley bolt.
* Socket set (metric): Similar sizes as the wrench set for better access in tight spaces.
* Ratchet: For efficient use of sockets.
* Pliers: Needle-nose pliers might be helpful for dealing with electrical connectors.
* Screwdrivers (Phillips and flathead): Potentially needed for various access panels or shrouds.
* Jack and jack stands: Essential for safe working conditions. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* New alternator: Make sure you get the correct replacement for your Mystique's engine.
* Battery terminal cleaner: For cleaning battery terminals before disconnecting.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes from debris.
* Possibly a battery charger: To help maintain the car's computer settings. Some procedures might require disconnecting the battery and this will reset the car's computer.
General Steps (Consult your repair manual for specifics):
1. Disconnect the Battery: Always disconnect the negative (-) battery terminal first, then the positive (+). This prevents accidental shorts and electrical shocks.
2. Access the Alternator: This is often the trickiest part. The alternator is usually located on the engine's front, typically near the bottom. You might need to remove various components for easier access, such as:
* Serpentine Belt: This almost certainly needs to be removed. You'll need a serpentine belt wrench or a suitable alternative to loosen the tensioner pulley.
* Air Intake components: Possibly air filter housing, intake tube etc.
* Other hoses or brackets: Depending on your specific vehicle, there might be other components obstructing access to the alternator.
3. Remove the Alternator: Once you have access, you will need to unbolt the alternator from its mounting bracket. Usually, there are two or three bolts securing it.
4. Disconnect Electrical Connections: Carefully disconnect the wiring harness connectors from the alternator. Take note of how they connect to ensure correct reinstallation. Sometimes, you'll have to remove the alternator's bracket to unhook the wires.
5. Install the New Alternator: Reverse the removal process to install the new alternator. Make sure all bolts are securely tightened.
6. Reconnect Electrical Connections: Reconnect the wiring harness connectors to the new alternator.
7. Reconnect the Serpentine Belt: Reinstall the serpentine belt, ensuring proper routing around all pulleys. A misrouted belt can cause damage.
8. Reconnect the Battery: Reconnect the positive (+) terminal first, then the negative (-) terminal.
9. Test the Alternator: Start the engine and check the voltage using a multimeter to ensure the new alternator is charging the battery.
Important Notes:
* Consult your repair manual: This is crucial. The exact location and method for removing components will vary.
* Take pictures: Before disconnecting anything, take pictures to help you remember how things go back together.
* Label wires and connectors: This is crucial to prevent misconnections.
* Safety first: Always use jack stands and follow safe working practices.
If you are not comfortable performing this task yourself, it's always best to take your car to a qualified mechanic. Improper alternator replacement can lead to further damage to your vehicle's electrical system.
