Tools You'll Need:
* Socket wrench set: You'll need a socket that fits your spark plugs (likely 5/8" or 13/16", check your owner's manual). A ratchet and extension(s) will be very helpful to reach the plugs.
* Spark plug socket: This is a special socket with a rubber insert to grip the spark plug without damaging it. Don't use a regular socket – you'll likely strip the plug.
* Wrench (for the coil pack, if applicable): Some 1996 Town & Countries have coil-on-plug ignition, meaning each plug has its own coil. Others use a distributor cap and rotor. You'll need the appropriate wrench if you have coil packs.
* New spark plugs: Purchase the correct type and heat range for your engine. Your owner's manual specifies this.
* Gloves: Protect your hands from grease and dirt.
* Penetrating oil (like PB Blaster): This can help loosen stubborn plugs.
* Shop rags or paper towels: For cleaning.
* Optional: Spark plug gap tool: To check the gap of your new plugs (though pre-gapped plugs are common now).
* Torque wrench (recommended): To tighten the new plugs to the correct specification (found in your owner's manual). Over-tightening can damage the threads.
Procedure (General Steps - Adapt based on your engine):
1. Safety First: Disconnect the negative (-) terminal from your battery. This prevents accidental shorts and shocks.
2. Locate Spark Plugs: Consult your owner's manual for the exact location of the spark plugs. They're usually located on top of the engine, but accessing them might require removing some plastic covers or components.
3. Access the Spark Plugs: This is often the trickiest part. You might need to remove air intake components, various plastic covers, or other parts to get a clear shot at the spark plugs.
4. Remove the Coil Packs (if applicable): If your engine has coil-on-plug ignition, carefully disconnect and remove each coil pack. They usually just unplug and may be held down by a clip or bolt. Note how they are positioned for reinstallation.
5. Remove the Spark Plugs: Use the spark plug socket and ratchet to carefully remove the old spark plugs. Spray penetrating oil on the plugs if they're difficult to loosen and let it sit for a few minutes. Turn the socket counter-clockwise. Don't force it; a stripped plug is a major headache.
6. Inspect Old Spark Plugs: Examine the old plugs for wear and tear, which can indicate engine problems. Note the electrode gap if you want to compare it to the new plugs.
7. Install New Spark Plugs: Carefully install the new spark plugs, screwing them in by hand initially until they're snug. Then, use the spark plug socket and ratchet to tighten them further. Do not over-tighten! Use a torque wrench if you have one to tighten to the manufacturer's specifications (consult your manual).
8. Reconnect Coil Packs (if applicable): Reinstall the coil packs, ensuring they're properly seated and connected.
9. Reassemble Everything: Put back all the components you removed earlier, making sure everything is properly connected.
10. Reconnect Battery: Reconnect the negative (-) battery terminal.
11. Start the Engine: Start the engine and listen for any unusual noises. If everything's fine, you've successfully changed your spark plugs.
Important Considerations:
* Consult your owner's manual: This is crucial. The specifics of your engine will vary, and your manual will have diagrams and torque specifications.
* Take pictures: Before you start disconnecting anything, take photos so you remember how everything goes back together.
* Don't force anything: If something is stuck, stop and investigate. Forcing things can lead to damage.
* Cleanliness: Keep the area clean to avoid dropping anything into the engine.
If you're not comfortable performing this task, it's best to take your vehicle to a qualified mechanic. Replacing spark plugs incorrectly can damage your engine.
