Here's a general overview. Specific steps and torque specs will vary depending on the year and engine of your S10. Always consult a repair manual specific to your S10's year and model. This information is for guidance only and doesn't replace a proper manual.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the vehicle from rolling.
* Socket wrench set (metric): Various sizes, including extensions and ratchets.
* Torque wrench: Crucial for properly tightening bolts to prevent damage.
* Pry bar or large screwdriver: To help loosen stubborn mounts.
* Hammer (possibly): May be needed to help break loose rusted bolts.
* Penetrating oil (like PB Blaster): Soak rusted bolts for several hours before attempting removal.
* New motor mounts: Make sure you get the correct ones for your specific S10.
* Gloves and safety glasses: Protect yourself.
* Possibly a engine support bar: To help support the engine while removing and installing mounts. Highly recommended.
General Steps (Consult your repair manual for precise instructions and torque specifications):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks. Securely support the vehicle with jack stands under the frame, not the jack.
2. Disconnect the Battery: Disconnect the negative (-) battery terminal to prevent electrical shorts.
3. Access the Motor Mounts: This will vary depending on the specific S10 model and engine. You'll likely need to remove some components to access the mounts (e.g., air intake components, exhaust components, etc.). Your repair manual will show you exactly what needs to come off.
4. Loosen and Remove the Mounting Bolts: Use penetrating oil liberally on the bolts several hours in advance. Loosen the bolts attaching the motor mount to both the engine and the frame. Sometimes these are difficult to reach.
5. Support the Engine: Before completely removing the bolts, use an engine support bar or a strong jack positioned under the oil pan to support the engine's weight. This prevents the engine from dropping and causing damage.
6. Remove the Old Motor Mounts: Carefully remove the bolts completely and remove the old motor mounts.
7. Install the New Motor Mounts: Install the new motor mounts in the reverse order of removal, ensuring they are seated correctly.
8. Tighten the Bolts: Tighten the bolts to the specifications listed in your repair manual. Use the torque wrench to prevent over-tightening or under-tightening.
9. Reconnect Everything: Reinstall all the components you removed earlier to access the motor mounts.
10. Lower the Engine Support (if used): Carefully lower the engine support after tightening all the bolts.
11. Reconnect the Battery: Reconnect the negative (-) battery terminal.
12. Test Drive: Carefully test drive the vehicle to ensure the new motor mounts are functioning correctly and there are no vibrations or noises.
Important Considerations:
* Rust: On older S10s, rust can be a major problem. Penetrating oil is your friend, and you may need to use heat to help break loose stubborn bolts. Consider replacing bolts if they are severely rusted or damaged.
* Torque Specs: Following the correct torque specifications is critical. Over-tightening can damage the mounts or engine block, while under-tightening can cause them to loosen and fail.
* Repair Manual: This is not a substitute for a proper repair manual specific to your S10. It provides detailed instructions and diagrams.
If you're not comfortable performing this repair yourself, it's best to take your S10 to a qualified mechanic. Engine mounts are critical for safe operation, and improper installation can lead to serious problems.
