Here's a general outline. Specific steps and difficulty may vary slightly depending on the exact engine (2.2L or 2.5L) and transmission (automatic or manual). Consult a repair manual specific to your year, model, and engine for precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools you'll likely need:
* Socket wrench set (metric): Various sizes, including deep sockets.
* Ratchet and extensions: To reach tight spots.
* Wrench set (metric): For various bolts and nuts.
* Torque wrench: Essential for tightening bolts to the manufacturer's specifications.
* Jack and jack stands: For safe vehicle support.
* Wheel chocks: For added safety.
* Penetrating oil (PB Blaster or similar): To loosen rusted bolts.
* Wire brush: To clean bolt heads and terminals.
* New starter motor: Make sure you get the correct one for your vehicle.
* Gloves and safety glasses: Always protect yourself.
General Steps (Consult your repair manual for specifics):
1. Disconnect the battery: Remove the negative (-) terminal first, then the positive (+).
2. Access the starter: This is the most challenging part. The starter is typically located on the transmission bell housing, often requiring removal of various components to reach it. This might involve:
* Removing some underbody components: Possibly plastic covers, heat shields, or other parts obstructing access.
* Partially or fully removing the air intake system: This provides better access in many cases.
* Possibly removing the exhaust downpipe (or at least loosening it): This depends on your specific model and how the starter is positioned. This is the most likely step requiring mechanical knowledge beyond basic DIY.
3. Disconnect the starter wiring: There will be at least two large wires connected to the starter – one positive and one ground. Carefully disconnect these. Take photos or make notes to remember how they were connected. A wire brush can help clean the connections.
4. Remove the starter bolts: These are usually 2-3 bolts holding the starter to the transmission. Use penetrating oil if necessary and allow it to soak before attempting to remove the bolts. They can be quite stubborn.
5. Remove the starter: Once the bolts are removed, carefully maneuver the starter out of its location. It may be a tight fit.
6. Install the new starter: Position the new starter in place, making sure it aligns correctly. Install the bolts, tightening them to the manufacturer's specified torque (see your repair manual).
7. Reconnect the wiring: Carefully attach the wiring to the new starter, ensuring a secure connection.
8. Reinstall removed components: Carefully put back everything you took off to access the starter.
9. Reconnect the battery: Attach the positive (+) terminal, then the negative (-) terminal.
10. Test the starter: Try to start the car. If it doesn't start, double-check all connections and ensure everything is properly secured.
Important Considerations:
* Difficulty: This is not a beginner-level repair. If you're not comfortable working on cars, consider taking it to a mechanic.
* Repair Manual: A repair manual specific to your vehicle is invaluable. It will provide detailed diagrams and instructions, saving you time and frustration.
* Safety First: Always prioritize safety. Work in a well-ventilated area, use jack stands, and disconnect the battery before working on electrical components.
This is a general guide. Consult your repair manual for precise steps and torque specifications for your specific 1997 Subaru Legacy GT Wagon. Attempting this repair without proper knowledge and tools could lead to damage to your vehicle or personal injury. If you're unsure about any step, it's best to seek professional help.
