Here's a general overview of the process. Remember, this is a simplified summary and lacks the detail necessary for safe and successful completion:
Preparation:
1. Safety First: Disconnect the negative battery terminal. Wear safety glasses, gloves, and appropriate clothing. Work in a well-ventilated area.
2. Gather Tools: You'll need a variety of tools, including sockets, wrenches, screwdrivers, a transmission jack, an engine hoist, jack stands, and possibly a torque wrench.
3. Drain Fluids: Drain the engine oil, coolant, transmission fluid, and power steering fluid.
4. Disconnect Components: Disconnect all electrical connectors, vacuum lines, fuel lines, and other components connected to the engine and transmission. Label everything carefully to avoid confusion during reassembly.
Removal Process (General Steps):
1. Remove Accessories: Remove the alternator, power steering pump, air conditioning compressor, and other accessories attached to the engine.
2. Disconnect Driveshaft: Disconnect the driveshaft from the transmission.
3. Remove Transmission: Support the transmission with a transmission jack. Disconnect the transmission from the engine, bellhousing bolts, and any linkage. Lower the transmission.
4. Disconnect Exhaust Manifold/Downpipe: Remove the exhaust manifold or downpipe from the engine.
5. Support the Engine: Securely attach an engine hoist to the engine's lifting points (consult your repair manual for the correct locations).
6. Remove Engine Mounts: Remove the engine mounts from the frame.
7. Lift the Engine: Carefully lift the engine with the engine hoist. Be mindful of clearance issues, especially with the steering column and other components.
8. Remove Engine: Once the engine is clear of the mounts and other obstructions, carefully maneuver it out from the engine bay.
Important Considerations:
* Engine and Transmission Type: The specific procedure will vary slightly depending on whether you have a 4.3L V6, a different engine, and whether your transmission is automatic or manual.
* Access: Working space is crucial. You may need to remove other components to gain sufficient access to the engine and transmission.
* Torque Specifications: Tightening bolts to the correct torque specifications is essential to prevent damage. Always consult your repair manual.
* Professional Help: If you are not comfortable with this type of work, it's best to seek professional help from a qualified mechanic. This is a complex job that can easily lead to damage if not done correctly.
This is a simplified overview. Do not attempt this repair without a detailed repair manual specific to your 1996 Chevy Blazer. Improper procedures can lead to serious injury or damage to your vehicle. Consult a professional if you have any doubts.
