1. Disconnect the Battery: This is crucial to prevent accidental shorts and damage to the electronic control modules.
2. Access the Distributor: Locate the distributor usually near the center of the engine. You might need to remove some parts to gain better access, such as air cleaner housing or other components obstructing your view.
3. Identify the Pickup Coil: The pickup coil is usually a small, rectangular or cylindrical component mounted within or near the distributor. It often has two wires connected to it.
4. Carefully Disconnect the Wires: Using needle-nose pliers or a small screwdriver, gently disconnect the wires from the pickup coil terminals. Make a note of which wire goes to which terminal if you are unsure of the wiring. Take a picture if needed.
5. Remove the Pickup Coil: This is where the procedure varies most.
* Method A (Screws): The coil might be held in place by screws. Carefully remove these screws, paying attention not to drop them into the distributor. The coil should then lift out.
* Method B (Clip or Retention Tab): Some pickup coils are held in place by a clip or a small retention tab. Carefully inspect the coil and its mounting to identify any clips or tabs. Gently pry these open or release them to free the coil.
* Method C (Press-Fit): In some rare cases, the coil might be a press-fit component. If this is the case, you might need a small flat-bladed tool to carefully pry the coil out. Be very gentle to avoid breaking the coil or damaging the distributor.
6. Inspect the Coil and Distributor: Once the coil is removed, inspect both the coil and the distributor housing for any signs of damage or wear.
7. Reassembly (If Replacing): If you're replacing the coil, ensure the new coil is the correct one for your vehicle. Installation is generally the reverse of removal.
Important Considerations:
* Distributor Rotor Position: Before starting, you may want to mark the rotor's position relative to the distributor housing, or use a timing light to verify the position after reassembly to prevent misfiring issues.
* Careful Handling: Pickup coils are relatively fragile. Handle them with care to avoid damage.
* Consult a Repair Manual: A repair manual specific to your 1987 Chrysler Fifth Avenue will provide the most accurate and detailed instructions. This is highly recommended, as the specific distributor design and the way the pickup coil is secured can vary.
* Professional Help: If you are uncomfortable performing this repair, consider taking your vehicle to a qualified mechanic.
Remember safety first! Work in a well-lit area with proper tools and always disconnect the battery before starting any electrical work.
