Before You Begin:
* Safety First: Disconnect the negative battery terminal. Use jack stands to support the car securely. Wear safety glasses and gloves.
* Repair Manual: Obtain a factory service manual or a reputable aftermarket repair manual. This is crucial for accurate procedures and torque specifications.
* Tools: Gather the necessary tools, including wrenches (metric), sockets, ratchets, screwdrivers, jack, jack stands, engine hoist, transmission jack (highly recommended), and potentially a torque wrench.
* Parts: Ensure you have the replacement engine, all necessary gaskets, seals, fluids (oil, coolant, transmission fluid), and any other parts that might need replacing (hoses, belts, etc.) during the process.
* Assistant: Having a helper will make the job significantly easier.
General Steps (This is a simplified overview – refer to your repair manual!):
1. Preparation: Disconnect the battery. Drain all fluids (oil, coolant, transmission fluid). Remove any components that obstruct access to the engine, such as air intake, belts, hoses, etc. Document the routing of everything before disconnecting.
2. Transmission Removal (Usually Necessary): This is often the most challenging part. You'll likely need to disconnect the driveshaft, shift linkage, and potentially other components. A transmission jack is highly recommended to support the transmission's weight.
3. Engine Mounts: Disconnect the engine mounts securing the engine to the chassis.
4. Exhaust System: Disconnect the exhaust manifold from the engine and the exhaust system.
5. Wiring Harness: Carefully disconnect the engine's wiring harness. Label everything meticulously to avoid confusion during reassembly.
6. Engine Hoist: Use an engine hoist to carefully lift the engine out of the engine bay.
7. Installation: Reverse the removal process to install the new engine. Pay close attention to aligning the engine with the transmission and securing it properly to the mounts.
8. Reconnection: Reconnect all components – wiring harness, exhaust system, transmission, hoses, belts, etc. Refer to your repair manual for proper routing and connections.
9. Fluid Fill and Check: Add the correct fluids (oil, coolant, transmission fluid). Check for leaks.
10. Testing: Start the engine and check for any leaks, unusual noises, or other problems.
Important Considerations:
* Transmission: The transmission may need to be serviced or replaced depending on its condition. Consider having it checked by a professional.
* Timing Belt: Replacing the timing belt is highly recommended during an engine replacement to avoid future problems.
* Professional Help: If you lack the experience or tools, consider seeking professional help from a mechanic. Engine replacement is a complex procedure.
This is a simplified overview. Always refer to a repair manual specific to your 1995 Geo Metro 1.3L for detailed instructions and safety precautions. Improperly performing this task can lead to serious damage to your vehicle or personal injury. If you are unsure about any step, seek professional assistance.
