Here's a general overview of the process. This is NOT a comprehensive guide and should not be substituted for a proper repair manual.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safely lifting the vehicle.
* Wheel chocks: To prevent the vehicle from rolling.
* Torque wrench: Crucial for tightening bolts to the correct specification.
* Sockets and wrenches: Various sizes will be needed, likely including metric.
* Ratchet: To quickly turn sockets and wrenches.
* Pry bar or large screwdriver: Might be needed to help loosen stubborn bolts.
* Engine support bar or hoist: Highly recommended to support the engine's weight while removing and installing the mounts. Improper support could cause engine damage.
* Penetrating oil (PB Blaster or similar): To help loosen rusted or seized bolts.
* New motor mounts: Get the correct replacements for your specific Caliber model and engine.
General Steps (Consult your repair manual for specific details):
1. Safety First: Disconnect the negative battery cable. Place the vehicle on a level surface, engage the parking brake, and use wheel chocks.
2. Raise and Support the Vehicle: Safely lift the vehicle using a jack and secure it on jack stands.
3. Access the Motor Mounts: Locate the motor mounts. The Caliber typically has at least three: one on the transmission and at least two on the engine itself. Access varies depending on the mount's location – you may need to remove some underbody plastic shields or other components.
4. Support the Engine: This is critical. Use an engine support bar or hoist to securely support the engine's weight. Failing to do this could cause the engine to drop and cause damage.
5. Remove the Old Motor Mounts: This usually involves removing several bolts from each mount. Use penetrating oil if needed and be prepared for resistance. Carefully remove each bolt and support the engine as you go.
6. Install the New Motor Mounts: Carefully align the new motor mounts and install the bolts, tightening them evenly and gradually. Do not overtighten. Refer to your repair manual for the correct torque specifications.
7. Lower the Engine: Slowly lower the engine, ensuring the mounts are properly seated.
8. Reassemble: Reinstall any removed components, such as underbody shields.
9. Lower the Vehicle: Carefully lower the vehicle using the jack.
10. Check for Leaks and Proper Mounting: Inspect for any leaks around the new mounts and ensure the engine is securely attached.
11. Reconnect the Battery: Reconnect the negative battery cable.
12. Test Drive: Take the vehicle for a test drive to verify that the problem is resolved.
Important Considerations:
* Repair Manual: A repair manual is absolutely essential. It will provide detailed instructions, torque specifications, and diagrams specific to your vehicle's year and engine.
* Engine Support: Improperly supporting the engine is a major risk. Use the appropriate tools.
* Bolt Removal: Be patient and persistent when removing bolts. Using penetrating oil and the correct tools is essential.
* Torque Specifications: Overtightening bolts can cause damage. Use a torque wrench and adhere to the manufacturer's specifications.
This is a complex repair. If you are not comfortable with this level of automotive repair, take your vehicle to a qualified mechanic. Improperly replacing motor mounts can lead to serious engine damage.
