Here's a general outline. This is not a comprehensive guide, and you should consult a repair manual specific to your 1995 Chevy Lumina for detailed instructions and torque specifications. Improper installation can lead to serious damage.
Tools You'll Need (at a minimum):
* Jack and jack stands (rated for the vehicle's weight)
* Wheel chocks
* Socket wrench set (metric)
* Torque wrench
* Pry bar or large screwdriver
* Hammer
* Penetrating oil (like PB Blaster)
* New motor mounts (get the correct ones for your engine)
* Possibly a engine support bar (to help support the engine)
Procedure (General Steps - Consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery cable. Secure the vehicle on jack stands, ensuring it's stable and level. Use wheel chocks on the wheels that remain on the ground.
2. Access: You'll need to access the motor mounts. This usually involves removing some components like air cleaner housing, various hoses, possibly the exhaust manifold (depending on which mount you're replacing), and potentially parts of the undercarriage shielding.
3. Loosen Bolts: Apply penetrating oil to the motor mount bolts well in advance to help break them loose. This may require significant effort. Use the correct size socket and ratchet to carefully loosen the bolts. Some mounts might have nuts on the bottom, requiring access from below.
4. Support the Engine: This is crucial. The engine is heavy and can easily shift or fall, potentially causing injury or damage. An engine support bar is highly recommended, but you might be able to improvise with sturdy wood and straps to help hold the engine in place.
5. Remove the Old Mounts: Once the bolts are loosened, carefully remove the old motor mounts. This can be tricky and may require a pry bar or other leverage tools. Take your time and be careful not to damage surrounding components.
6. Install New Mounts: Carefully install the new motor mounts, aligning them correctly. Tighten the bolts slightly, ensuring everything is properly aligned before fully tightening them.
7. Tighten Bolts: Use the torque wrench to tighten the bolts to the manufacturer's specified torque. This is critical to prevent premature failure.
8. Reassemble: Reinstall any components that were removed to access the motor mounts. Double-check all connections and hoses.
9. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
10. Test: Start the engine and check for any unusual noises or vibrations. Test drive the vehicle to ensure the mounts are properly functioning.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Chevy Lumina is essential. It will provide detailed diagrams, torque specifications, and specific procedures.
* Engine Support: Improper support of the engine during this repair can lead to serious damage or injury.
* Bolt Removal: Rust and corrosion can make bolt removal very difficult. Soak them with penetrating oil well in advance.
* Torque Specifications: Using the correct torque is crucial for the longevity of the new mounts.
This is a complex repair. If you are not comfortable performing this yourself, it is strongly recommended that you take your vehicle to a qualified mechanic. Attempting this without the proper knowledge and tools can lead to significant damage and injury.
