However, if you're determined to attempt this yourself, here's a general outline of the steps involved. This is a simplified overview and doesn't cover every detail. You'll need a detailed repair manual specific to your 1989 Ford Aerostar V6 for precise instructions and torque specifications.
Before You Begin:
* Safety First: Disconnect the negative battery terminal. Use jack stands to securely support the vehicle. Wear safety glasses and gloves.
* Gather Tools: You'll need a complete set of wrenches, sockets, ratchets, screwdrivers, a torque wrench, engine hoist (engine crane), transmission jack (highly recommended), and potentially various specialized tools depending on your specific engine and any unexpected issues.
* Repair Manual: Obtain a factory service manual or a reputable aftermarket repair manual specific to your 1989 Ford Aerostar with the V6 engine. This is absolutely crucial.
General Steps (in simplified form):
1. Disconnect Everything: Disconnect all electrical connectors, vacuum lines, fuel lines, and coolant hoses attached to the engine. Label everything carefully to ensure correct reassembly. Drain all fluids (oil, coolant, transmission fluid).
2. Remove Accessories: Remove the alternator, power steering pump, air conditioning compressor, and other accessories attached to the engine. This will make the engine lighter and easier to maneuver.
3. Exhaust System: Disconnect and remove the exhaust manifolds or downpipes from the engine.
4. Transmission: Depending on the type of transmission (automatic or manual), you'll need to disconnect it from the engine. This often requires removing the transmission mount(s) and potentially using a transmission jack to support the transmission as you separate it from the engine. This is one of the most challenging parts of the process.
5. Engine Mounts: Remove the engine mounts that secure the engine to the vehicle's frame.
6. Lift the Engine: Carefully use the engine hoist to lift the engine out of the engine bay. You'll likely need to maneuver it carefully to clear the firewall and other obstacles. A transmission jack to support the transmission is highly recommended at this stage.
7. Remove Engine: Once clear of the engine bay, carefully lower the engine onto a suitable stand.
Important Considerations:
* Weight: The engine is heavy. Use proper lifting techniques and equipment to avoid injury.
* Accessibility: The Aerostar's engine bay isn't particularly spacious, making this a challenging job.
* Bolts & Fasteners: Many bolts may be rusted or difficult to remove. Use penetrating oil and appropriate tools to avoid stripping them.
* Torque Specifications: Use a torque wrench and consult your repair manual for the proper torque specifications for all bolts and fasteners.
This is a high-level overview. The specific steps and procedures will vary based on your exact vehicle and engine configuration. Again, I strongly urge you to consult a detailed repair manual and consider seeking professional help. This job is best left to experienced mechanics with the proper tools and equipment.
