Here's a general outline. Specific details may vary slightly depending on the exact engine and mount design, so consult a repair manual specific to your 1998 Ford Windstar (Haynes or Chilton manuals are good options). Pictures will be invaluable during this process.
Tools you'll likely need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the vehicle from rolling.
* Torque wrench: Crucial for tightening bolts to the correct specifications.
* Sockets and wrenches (metric): A variety of sizes will be necessary.
* Ratchet: For quicker bolt removal and installation.
* Extensions and universals: To reach hard-to-access bolts.
* Pry bar: May be needed to help separate the engine mount from the engine or frame.
* Engine hoist or transmission jack (recommended): To support the engine while you work. This significantly reduces the risk of engine damage. If you don't have one, you might be able to carefully support the engine with wood blocks and a strong jack. But be extremely careful.
* New engine mounts: Make sure you get the correct replacements for your vehicle.
* Shop rags or paper towels: To keep things clean.
* Penetrating oil (like PB Blaster): To help loosen rusted bolts.
Steps:
1. Safety First: Park the Windstar on a level surface, engage the parking brake, and use wheel chocks. Disconnect the negative battery terminal.
2. Access: Raise the front of the vehicle securely using the jack and place it on jack stands. Locate the engine mounts. There are usually two main mounts (one on each side of the engine) and possibly a smaller, transmission mount.
3. Disconnect Components: This is where a repair manual is essential. You'll likely need to disconnect various components to access the mount bolts. This could include:
* Electrical connectors: Disconnect any wiring harnesses connected to the mounts or nearby components.
* Vacuum lines: Carefully disconnect and label any vacuum lines.
* Other brackets or components: Remove any brackets or components interfering with access to the mount bolts.
4. Remove the Old Mounts: Apply penetrating oil to the bolts several hours in advance to help loosen them. Use the appropriate sockets and wrenches to carefully remove the bolts securing the engine mount to the engine and the chassis. It's usually a multi-bolt setup. Be mindful of the weight of the engine. Using an engine hoist or transmission jack will prevent the engine from dropping unexpectedly.
5. Install New Mounts: Carefully install the new engine mounts, ensuring they are properly seated. Tighten the bolts to the manufacturer's specified torque using your torque wrench.
6. Reconnect Components: Reconnect all the components you disconnected earlier, ensuring everything is properly secured.
7. Lower the Vehicle: Carefully lower the vehicle to the ground.
8. Test Drive: Once everything is reassembled, start the engine and check for any unusual noises or vibrations. Take a short test drive to ensure the engine mounts are working correctly.
Important Considerations:
* Torque Specifications: Always consult your repair manual for the correct torque specifications for the engine mount bolts. Over-tightening can damage the mounts or surrounding components, while under-tightening can lead to looseness and failure.
* Alignment: Make sure the engine is properly aligned before tightening the bolts. Misalignment can cause stress on the mounts and other components.
* Professional Help: If you're not comfortable performing this repair yourself, take your Windstar to a qualified mechanic. Replacing engine mounts incorrectly can lead to significant damage to your vehicle.
This is a general guide; always refer to a repair manual specific to your 1998 Ford Windstar for detailed instructions and torque specifications. Remember to prioritize safety throughout the entire process.
