7 Check Timing: Using the timing light, check and adjust the ignition timing if necessary.
8 Clean Components: Clean the distributor cap and rotor with a brush and electrical contact cleaner to remove
any dirt or rust.
9 Lubrication: Apply a small amount of dielectric grease to the inside of the distributor cap to prevent moisture
build-up.

10 Reassemble: Put the distributor cap and rotor back in place and secure them properly.
11 Reconnect the battery: Reconnect the negative terminal of the battery.
12 Start the engine: Start the engine and check for smooth running.
13 Recheck Timing: Using the timing light, recheck to make sure the ignition timing is within the specified limits.

14 Test Drive: Take the vehicle for a test drive to make sure everything is working properly.
15 Final Inspection: Once the test drive is complete, inspect the distributor and surrounding components for any
signs of leakage or deformation.

Electronically Controlled Distributor:
1 Preparation: Follow steps 1-3 from mechanically controlled distributor type procedure.
2 Diagnostic Scan: Connect the diagnostic scanner to the vehicle’s 080-11 port and retrieve any trouble codes
related to the distributor or ignition system.
3 Inspect components: Check distributor cap, rotor, ignition coil and wiring harness for any visible damage or
signs of wear.

4 Test Sensors: Test the crankshaft position sensor, camshaft position sensor, and ignition control module for
proper operation using a multimeter.
5 Check the wiring: Inspect the wiring harness for any broken wires, loose connections, or corrosion. Repair or
