Tools You'll Likely Need:
* Socket set (metric): You'll need various sizes, likely including 10mm, 13mm, 14mm, and possibly larger.
* Wrench set (metric): Useful for accessing difficult-to-reach bolts.
* Ratchet and extensions: To reach bolts in tight spaces.
* Jack and jack stands: Essential for safe working conditions. Never work under a vehicle supported only by a jack.
* Wheel chocks: To prevent the vehicle from rolling.
* Breaker bar (optional but helpful): Starter bolts can be stubborn.
* Penetrating oil (PB Blaster or similar): Helps loosen rusted or seized bolts.
* Battery terminal cleaner: A good idea before starting.
* New starter motor: Make sure you get the correct one for your Bravada's engine.
* Gloves and safety glasses: Protect yourself from potential injury.
* Wire brush: To clean connections.
General Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shocks and short circuits. Disconnect the negative (-) terminal first, then the positive (+) terminal.
2. Access the Starter: The starter on a Bravada is typically located on the driver's side of the engine, near the bell housing (the part of the transmission that connects to the engine). You'll likely need to remove some components to access it fully. This often involves:
* Removing the air intake system (or parts of it): This might involve disconnecting hoses and clamps.
* Removing some engine components: This could include the battery (if it's in the way), possibly the air cleaner housing, or possibly even parts of the exhaust system. A repair manual is critical here.
* Accessing the starter bolts: These are usually located on the top and bottom of the starter.
3. Remove the Starter: Once you have access, apply penetrating oil to the starter mounting bolts and let it sit for a while. This will help break free any corrosion. Then, using the appropriate sockets and wrenches, carefully remove the bolts securing the starter to the engine block. The starter may be a little heavy, so be prepared to support its weight as you remove it.
4. Compare the Old and New Starters: Before installing the new starter, compare it carefully to the old one. Ensure all connections are identical and in the same location.
5. Install the New Starter: Install the new starter in reverse order of removal. Ensure that the starter is properly aligned before tightening the bolts. Tighten the bolts securely, but don't overtighten. Consult your repair manual for proper torque specifications.
6. Reconnect Everything: Reinstall all components you removed to access the starter, ensuring all hoses and wires are correctly connected.
7. Reconnect the Battery: Connect the positive (+) terminal first, then the negative (-) terminal.
8. Test the Starter: Try starting the engine. If it doesn't start, double-check all connections.
Important Notes:
* This is a general outline. The specific steps and tools needed will vary depending on the exact model and engine of your 1992 Oldsmobile Bravada.
* Consult a repair manual: A Haynes or Chilton repair manual specific to your vehicle is invaluable. These manuals provide detailed instructions with diagrams and torque specifications.
* Safety first: Always prioritize safety. Use jack stands, chocks, and wear appropriate safety gear. If you're not comfortable performing this repair, take your vehicle to a qualified mechanic.
Working under a car can be dangerous. If you lack experience, seeking professional help is strongly recommended. Improper repair can lead to damage to your vehicle or even serious injury.
