Tools You'll Need:
* Socket wrench set (metric)
* Screwdrivers (Phillips and flathead)
* Distributor wrench (special tool, sometimes a socket fits)
* Timing light (essential for proper timing)
* Ignition wrench (for the coil wire)
* Flashlight
* Pen and paper (for marking and noting connections)
* Safety glasses
* Gloves
* Shop rag or towels
Procedure:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Locate the Distributor: It's usually on the passenger side of the engine, towards the front.
3. Mark the Distributor Position: Before removing anything, carefully mark the distributor's position relative to the engine block. Use a marker to draw a line between the distributor housing and the engine. This is CRITICAL for proper reinstallation and avoiding timing issues. Also, note the rotor position relative to the distributor cap.
4. Disconnect Components:
* Vacuum Advance Line: Disconnect the vacuum line connected to the distributor.
* Spark Plug Wires: Carefully remove and label each spark plug wire, noting which cylinder each wire goes to. Use a diagram if necessary. A numbering system works well (e.g., 1-6). Misplacing these will cause misfires and potential damage.
* Distributor Cap: Remove the distributor cap. Note the rotor position relative to the cap and the number of the cylinder it's pointing to.
* Wiring Harness Connector: Disconnect the electrical connector from the distributor.
5. Remove the Distributor: This is the trickiest part. You'll likely need a distributor wrench or a suitably sized socket to loosen the hold-down bolt (often a large bolt). The distributor may be somewhat stiff; gently rock it back and forth while loosening the bolt. Once loose, carefully lift the distributor straight up and out.
6. Install the New Distributor:
* Lubricate: Lightly lubricate the distributor's O-ring (if present).
* Position: Carefully align the new distributor with the markings you made earlier. Ensure it sits straight and flush.
* Tighten the Bolt: Gently tighten the hold-down bolt to the specified torque (check your repair manual). Don't overtighten.
7. Reconnect Components: Reinstall all the components in the reverse order of removal, ensuring the spark plug wires are connected correctly. Double-check this step!
8. Reconnect the Battery: Reconnect the battery's negative terminal.
9. Set the Ignition Timing: This is extremely important. You will need a timing light. Refer to your repair manual for the correct procedure. The timing light will show you the timing mark on the crankshaft pulley. You will likely need to adjust the distributor slightly to achieve the proper timing. Incorrect timing can damage the engine.
Important Considerations:
* Repair Manual: A repair manual specific to your 1987 Chevy Celebrity 2.8L is essential. It will provide detailed instructions, torque specifications, and diagrams.
* Professional Help: If you're not comfortable with this procedure, it's best to take your vehicle to a qualified mechanic. Incorrectly installing the distributor can cause significant engine damage.
* Safety: Always prioritize safety. Wear safety glasses and gloves. Work in a well-ventilated area.
This guide provides a general overview. The specific details might vary slightly depending on your vehicle's configuration. Refer to a repair manual for precise instructions and safety precautions. Good luck!
