Here's a general overview. Specific steps and torque specifications will vary depending on the exact engine (likely a V6) and the type of motor mounts your car has (hydraulic or solid). You'll need a detailed repair manual specific to your 1987 Buick Electra Park Avenue to guide you accurately.
Tools You'll Likely Need:
* Repair Manual: Absolutely essential. A Haynes or Chilton manual for your specific year and model will provide detailed instructions and torque specifications.
* Jack and Jack Stands: Safely support the vehicle. Never work under a vehicle supported only by a jack.
* Engine Support Bar: Essential to prevent the engine from falling when disconnecting mounts. This is a crucial safety precaution.
* Sockets, Wrenches, and Ratchets: A variety of sizes, including metric and possibly SAE.
* Torque Wrench: Crucial for tightening bolts to the correct specifications to prevent damage.
* Pry Bar: May be needed to help separate the old mounts.
* Hammer (Rubber Mallet preferred): For carefully tapping components loose.
* Penetrating Oil (PB Blaster or similar): To loosen rusted or seized bolts.
* Safety Glasses and Gloves: Protect yourself from injury.
General Steps (Consult your repair manual for precise instructions):
1. Safety First: Disconnect the negative battery cable. Secure the vehicle on jack stands.
2. Access the Motor Mounts: This often involves removing various components like the air cleaner assembly, possibly parts of the exhaust system, and potentially some underbody shields. Your repair manual will show you exactly what needs to come off.
3. Support the Engine: Use the engine support bar to securely hold the engine in place. This is critical to prevent it from dropping or shifting during the mount removal.
4. Remove the Old Motor Mounts: This typically involves removing nuts and bolts securing the mounts to both the engine and the frame. Penetrating oil may be necessary to loosen rusted bolts. Be patient and work carefully.
5. Install the New Motor Mounts: Carefully align the new mounts and secure them with the correct bolts and nuts. Use the torque wrench to tighten the bolts to the manufacturer's specifications found in your repair manual. This is essential to prevent damage and ensure proper function.
6. Lower the Engine Support Bar: Carefully lower the engine support bar once the new mounts are securely fastened.
7. Reinstall Removed Components: Reassemble everything you removed in step 2, ensuring all connections are properly made.
8. Reconnecting the Battery: Reconnect the negative battery cable.
9. Test Drive: After completing the repair, perform a short test drive to check for vibrations or unusual noises. If anything feels wrong, immediately stop driving and re-examine your work.
Important Considerations:
* Type of Mounts: Determine if your mounts are hydraulic or solid before purchasing replacements.
* Torque Specifications: Always use a torque wrench and adhere to the manufacturer's specifications to prevent damage.
* Professional Help: If you're uncomfortable with any of these steps, or lack the necessary tools or experience, it's best to have a qualified mechanic perform the repair.
This is a general guide. Always refer to your vehicle's repair manual for precise instructions and torque specifications. Failure to do so could result in engine damage or injury. Remember safety is paramount throughout the entire process.
