Tools You'll Need:
* Jack and jack stands: Essential for safely supporting the engine.
* Engine support bar: Highly recommended to prevent the engine from dropping unexpectedly.
* Sockets and wrenches: A variety of sizes, likely including metric and SAE. Check your manual for specific sizes.
* Ratchet and extensions: To reach tight spaces.
* Breaker bar: May be needed to loosen stubborn bolts.
* Torque wrench: Crucial for properly tightening bolts during reassembly.
* Penetrating oil (like PB Blaster): Soak bolts beforehand to help break them loose.
* Pry bar: Might be needed to help separate the mount from the frame.
* Gloves and safety glasses: Protect yourself from injury.
Procedure:
1. Disconnect the battery: This is a crucial safety step to prevent accidental shorts.
2. Support the engine: Securely jack up the engine using a suitable jack point (consult your repair manual). Then, place a sturdy engine support bar under the engine to prevent it from falling. This is absolutely critical.
3. Locate motor mounts: The El Camino's motor mounts are typically located on the sides of the engine, connecting it to the frame. You'll have at least two, possibly more depending on the engine.
4. Remove accessory components: Depending on your engine and the location of the mounts, you may need to temporarily remove or loosen some components to access the mount bolts. This could include things like the alternator, power steering pump, or other accessories.
5. Remove the motor mount bolts: Use the appropriate sockets and wrenches to remove the bolts securing the motor mount to both the engine and the frame. Apply penetrating oil generously several hours before starting. Often these bolts are very tight.
6. Separate the motor mount: Once the bolts are removed, carefully separate the motor mount from the engine and the frame. This may require a pry bar, but use caution to avoid damaging the mount or surrounding components.
7. Remove the old motor mount: Once separated, carefully remove the old motor mount.
8. Installation (Reverse of Removal): Installing new motor mounts is the reverse of the removal process. Ensure the new mounts are correctly seated before tightening bolts. Use the torque wrench to tighten the bolts to the manufacturer's specifications.
Important Considerations:
* Engine weight: The engine is heavy! Take all necessary precautions to prevent injury and damage.
* Bolt access: Access to the motor mount bolts can be tight. Use extensions and the correct tools.
* Torque specifications: Using the correct torque is critical to prevent damage and ensure proper performance. Consult your repair manual.
* Alignment: Make sure the engine is properly aligned before tightening the motor mount bolts.
* Professional help: If you are uncomfortable performing this task, consider seeking professional help from a mechanic.
This is a general guide. A repair manual specific to your 1979 Chevy El Camino is highly recommended. It will provide detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle. Improperly performing this repair could lead to engine damage or injury. Always prioritize safety.
