Tools You'll Likely Need:
* Jack and Jack Stands: Absolutely crucial for safety.
* Wheel Chocks: Essential for added safety.
* Torque Wrench: To tighten bolts to the correct specifications.
* Socket Set (Metric): Various sizes, likely including 13mm, 15mm, and possibly larger.
* Wrench Set (Metric): May be needed for some fasteners.
* Pry Bar: To help separate the motor mounts from the frame.
* Hammer (Rubber mallet preferred): For gently persuading parts.
* Floor Jack (optional but helpful): To help support the engine.
* Engine Support Bar (highly recommended): Prevents the engine from dropping and causing damage.
* Penetrating Oil (like PB Blaster): To loosen rusted or stuck bolts.
* Safety Glasses and Gloves: Protect yourself.
General Steps (This is a simplified overview; consult your repair manual for specifics):
1. Safety First: Disconnect the negative battery terminal. Secure the vehicle on jack stands with wheel chocks in place.
2. Access: You'll likely need to remove some components for better access to the motor mounts. This might include:
* Air cleaner assembly: Makes room to work above the engine.
* Possibly parts of the exhaust system: Depending on mount location and your specific vehicle.
* Some undercarriage components: May need to be removed or loosened to access lower mounts.
3. Support the Engine: Use a floor jack and an engine support bar to support the engine's weight. This is CRITICAL to prevent damage. Position the jack under the oil pan or engine block, distributing the weight evenly.
4. Remove the Old Motor Mounts: This is the most labor-intensive part. Each mount will have several bolts attaching it to both the engine and the frame.
* Apply penetrating oil: To the bolts several hours before you start.
* Carefully remove the bolts: Work methodically, ensuring you don't strip any threads.
* Separate the mount: Use a pry bar carefully to separate the old motor mounts from the engine and frame. Expect some resistance.
5. Install the New Motor Mounts: This is the reverse of removal. Ensure the new mounts are properly aligned and seated before tightening the bolts.
6. Tighten Bolts: Use your torque wrench to tighten the bolts to the manufacturer's specified torque. This is crucial to prevent premature failure.
7. Reinstall Components: Put everything back in place that you removed earlier.
8. Lower the Engine: Carefully lower the engine using the jack, removing the support bar once the engine is resting on the mounts.
9. Check for Leaks: After reinstalling everything, start the engine and check for any leaks around the motor mounts or any other areas you worked on. Look for unusual noises or vibrations as well.
10. Test Drive: Take a test drive to verify that the problem is solved.
Important Considerations:
* 4WD Specifics: Four-wheel-drive S10 Blazers may have unique challenges due to the transfer case and drivetrain components. This makes accessing certain mounts more difficult.
* Year Variations: The exact location and design of the motor mounts can vary significantly between model years.
* Repair Manual: A repair manual is indispensable for this job. It will provide detailed diagrams, torque specifications, and step-by-step instructions specific to your vehicle.
This is a general guide. Attempting this repair without experience can lead to damage or injury. If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic.
