Here's a general overview of the process. Specific details may vary slightly depending on the engine (4.3L, 5.7L, etc.) and whether it's 4WD or 2WD. Always consult a repair manual specific to your Blazer's year, engine, and drivetrain for detailed instructions and torque specifications.
Tools You'll Likely Need:
* Jack and jack stands: Crucial for safety. Never work under a vehicle supported only by a jack.
* Wheel chocks: To secure the vehicle.
* Engine support bar: This is highly recommended to prevent the engine from dropping unexpectedly.
* Sockets and wrenches (metric): Various sizes will be needed.
* Ratchet and extensions: To reach tight spots.
* Torque wrench: Essential for properly tightening bolts to prevent damage.
* Pry bar or large screwdriver: May be needed to help loosen stubborn bolts.
* Penetrating oil (like PB Blaster): Soak bolts overnight if they are rusty or seized.
* New motor mounts: Make sure you get the correct ones for your specific Blazer.
* Gloves and safety glasses: Protect yourself.
General Steps (Highly Simplified):
1. Safety First: Disconnect the negative battery terminal. Secure the vehicle with jack stands and wheel chocks.
2. Access the Mounts: This involves removing various components that obstruct access to the motor mounts. This could include:
* Air intake system
* Various belts and hoses (label everything carefully before disconnecting!)
* Exhaust components (potentially, depending on mount location)
* Possibly parts of the front suspension or steering components (again, depending on the specific mount location)
3. Support the Engine: Use an engine support bar to secure the engine and prevent it from falling.
4. Remove the Old Mounts: This usually involves removing bolts that secure the mount to both the engine and the frame. Penetrating oil is your friend here. These bolts can be incredibly stubborn.
5. Install the New Mounts: Carefully install the new motor mounts, ensuring they are properly seated.
6. Reassemble Everything: Carefully reinstall all the components you removed in reverse order, paying close attention to proper routing of belts and hoses.
7. Lower the Engine: Carefully lower the engine support bar once everything is reassembled.
8. Reconnecting Battery: Reconnect the negative battery terminal.
9. Test Drive: After everything is reassembled, start the engine and check for any leaks or unusual noises. Take a short test drive to make sure everything is working correctly.
Important Considerations:
* Torque Specifications: Using a torque wrench and following the manufacturer's torque specifications is crucial to prevent damage to the engine and frame.
* Repair Manual: A repair manual specific to your 2000 Chevy Blazer is highly recommended. It will provide detailed instructions, diagrams, and torque specifications.
* Professional Help: If you're not comfortable performing this repair, take your Blazer to a qualified mechanic. Improperly installed motor mounts can lead to serious engine damage.
This is a simplified overview. The actual process is far more involved and requires a detailed understanding of automotive mechanics. Again, consult a repair manual specific to your vehicle before attempting this repair. Safety should be your top priority.
