However, here's a general outline of the process. Remember this is a simplified overview, and specifics may vary depending on the year and model of your Dodge 318. Always consult a repair manual specific to your vehicle's year and model for precise instructions and torque specifications.
Tools you'll likely need:
* Socket wrench set (metric)
* Wrenches (metric)
* Screwdrivers (Phillips and flathead)
* Distributor removal tool (may be necessary)
* Timing light
* Timing pointer/mark (if not already on the engine)
* Shop rags
* Safety glasses
* Gloves
Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Mark the Distributor Position: Before removing anything, carefully mark the distributor's position relative to the engine. Use a marker to draw a line connecting the distributor body to the engine block. This will help you reinstall it correctly. Also note the rotor's position relative to the distributor cap.
3. Remove the Distributor Cap: Carefully remove the distributor cap and note the position of the rotor and wires. Take a picture or make a detailed diagram to ensure you reinstall them correctly.
4. Disconnect the Wires: Disconnect the spark plug wires from the distributor cap, being careful to keep track of which wire goes where.
5. Disconnect the Electrical Connections: Disconnect the vacuum advance (if present) and the wiring harness connector from the distributor.
6. Remove the Distributor Hold-Down Clamp: Loosen and remove the clamp holding the distributor in place.
7. Remove the Distributor: This is where a distributor removal tool can be helpful. It's often a gear puller specifically designed for this task. Some distributors can be removed by hand, but others may require a gentle rocking motion. Be very careful not to damage the distributor shaft or the engine block.
8. Install the New Distributor: Carefully align the new distributor according to your markings and the engine's timing marks. Push it straight down, ensuring it sits correctly in the distributor housing.
9. Tighten the Hold-Down Clamp: Secure the distributor with the hold-down clamp.
10. Reconnect the Electrical Connections: Reconnect the vacuum advance (if applicable), the wiring harness connector, and the spark plug wires according to your markings or diagram.
11. Reinstall the Distributor Cap: Replace the distributor cap, ensuring the rotor is aligned correctly.
12. Reconnect the Battery: Reconnect the battery positive (+) terminal.
13. Set the Ignition Timing: Use a timing light to verify and adjust the ignition timing according to your vehicle's specifications (found in your repair manual). This is crucial for proper engine operation. Incorrect timing can lead to poor performance, reduced fuel economy, and potential engine damage.
Important Considerations:
* Rotor Position: The rotor must point to the correct cylinder at the number one cylinder's firing position for proper ignition timing.
* Vacuum Advance: Ensure the vacuum advance connection is correctly installed and functioning.
* Repair Manual: Always consult a repair manual specific to your vehicle for detailed instructions, torque specifications, and diagrams.
Again, replacing a distributor is not a trivial task. If you're unsure about any step, seek professional help. Improper installation can lead to significant engine damage.
