Here's a general overview. Specific steps and torque specifications will vary slightly depending on the exact engine (3.0L Vulcan or 3.0L Duratec) and transmission (automatic or manual). Always consult a repair manual specific to your vehicle's year, make, model, and engine for precise instructions and torque values. A Haynes or Chilton manual is a good investment.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely crucial for safety.
* Wheel chocks: To prevent the car from rolling.
* Socket set and wrenches: Various sizes, including metric.
* Torque wrench: Essential for proper tightening of bolts.
* Pry bar or engine hoist (highly recommended): To help maneuver the engine. An engine hoist makes the job significantly easier and safer.
* Ratchets and extensions: To reach difficult bolts.
* Penetrating oil (PB Blaster, etc.): To loosen rusted bolts.
* New motor mounts: Make sure you get the correct ones for your specific vehicle.
* Gloves and safety glasses: Protect yourself.
* Shop rags or absorbent cloths: To clean up spills.
General Steps (Consult your repair manual for specifics):
1. Safety First: Disconnect the battery's negative terminal. Secure the vehicle on jack stands. Engage the parking brake and use wheel chocks.
2. Access the Mounts: This will require removing various components to access each mount. This often involves removing:
* Exhaust components: Parts of the exhaust system may need to be temporarily removed to provide clearance.
* Transmission or accessory components: Depending on the mount location, you may need to remove or loosen some components attached to the transmission or engine accessories (like the power steering pump or alternator).
* Underbody shields/splash guards: These need to be removed for better access.
3. Support the Engine: Before removing any mount bolts, use a jack or engine hoist to support the engine to prevent it from dropping unexpectedly. Place the jack under the engine's oil pan or a suitable support point.
4. Remove the Old Mounts: Carefully remove the bolts securing each motor mount to the engine and the chassis. Penetrating oil is your friend here. Note the orientation and position of any washers or shims.
5. Install the New Mounts: Carefully install the new motor mounts, ensuring they are seated correctly. Tighten the bolts to the manufacturer's specified torque using a torque wrench.
6. Reinstall Components: Carefully reinstall any components you removed earlier, ensuring everything is properly connected and secured.
7. Lower the Engine: Slowly lower the engine using the jack or engine hoist, ensuring the weight is evenly distributed and that nothing interferes.
8. Reconnect Battery: Reconnect the battery's negative terminal.
9. Test Drive: After reassembly, test drive the vehicle to ensure the mounts are correctly installed and there are no vibrations or other issues.
Important Considerations:
* Rust: Older vehicles are prone to rusted bolts. Use penetrating oil liberally and allow it to soak in for a while before attempting to remove any bolts.
* Torque Specifications: Using the correct torque specifications is crucial to prevent damage. Always refer to your repair manual.
* Engine Hoist: Using an engine hoist is highly recommended to make the process safer and easier. Doing this job without one requires considerable skill and patience.
* Professional Help: If you're not comfortable with this level of automotive repair, consider taking your vehicle to a qualified mechanic. The cost of a professional repair is often less than the potential damage from an improperly installed mount.
This is a general guide; always consult a repair manual specific to your vehicle before attempting this repair. Improper installation can lead to engine damage and safety hazards. Remember safety first!
