Tools You'll Need:
* New distributor cap: Make sure you get the correct part for your vehicle.
* Socket wrench and sockets: You'll likely need a socket to remove the hold-down bolt(s) for the distributor cap. Consult your repair manual for the correct size.
* Screwdriver (possibly): Some distributor caps might have screws holding the cap in place.
* Needle-nose pliers (optional): To help remove any stubborn wires.
* Gloves: To keep your hands clean and prevent accidental damage.
* Shop rag: To clean up any dirt or grime.
Procedure:
1. Safety First: Disconnect the negative terminal from your car battery before starting any work. This prevents accidental shorts and electrical shocks.
2. Locate the Distributor: The distributor is usually located under the hood near the engine's top. Your repair manual will show its exact location.
3. Remove the Distributor Cap:
* Identify the hold-down clamp or screws: There might be a clamp that simply clips onto the distributor, or it could be held down by one or more screws.
* Carefully remove the clamp or screws: Loosen and remove the fasteners. Be gentle to avoid damaging the distributor cap.
* Lift off the distributor cap: Once the fasteners are removed, gently lift the cap straight up. Do this slowly to avoid breaking the rotor button connection inside.
4. Inspect the Rotor Button (Inside the Cap): The rotor button is usually a small, spinning component inside the distributor cap. If it's damaged or worn, you'll replace it with the new cap's rotor button; if not, you can reuse the old one if the new cap's button is separate from the cap itself.
5. Clean the Distributor: Use a clean shop rag to carefully wipe down the distributor and the area around it, removing any dirt, grime, or debris.
6. Install the New Distributor Cap: Align the new distributor cap with the distributor housing, ensuring the rotor button is correctly positioned to the number one spark plug wire location. (Your repair manual will show you the correct firing order and how to locate the number one cylinder.)
7. Connect the Spark Plug Wires: Carefully connect the spark plug wires to their correct terminals on the new distributor cap. Double-check the order! Incorrect wiring can cause serious engine problems or damage. Consult your repair manual to confirm the firing order.
8. Secure the Distributor Cap: Reattach the hold-down clamp or screws to secure the new distributor cap firmly in place.
9. Reconnect the Battery: Reconnect the negative battery terminal.
10. Test: Start the engine to ensure it runs smoothly. If you have any issues, double-check your work, especially the spark plug wire connections.
Important Considerations:
* Firing Order: The firing order for your 1998 Acura Integra GS is crucial. Get this information from your repair manual. Connecting the spark plug wires incorrectly can severely damage your engine.
* Gaps: The gap between the distributor cap and rotor can cause misfires.
* Rotor Wear: Sometimes the rotor itself inside the distributor may be worn. This may require an additional part to be replaced.
If you're not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic. Incorrectly installing the distributor cap can cause serious engine damage. Remember to consult your repair manual for specific instructions and diagrams related to your vehicle.
