• Q: How to service and repair the distributor on 2002 Chevrolet Astro?

  A: Start by removing the engine cover to service and repair the distributor. Whitish buildup around the cap terminals, cap discoloration and yellowing of rotor cap and darkening with some carbon under rotor segment is normal. replacement is only done if there are driveability concerns. Check for caps leaks, small holes or carbon tracks between the terminal traces. Take off the cap and apply a DMM by putting one lead on a cap terminal while probing all the other terminals and the central carbon ball with the second lead, rotating the base lead to the next terminal and repeating the process until all secondary terminals have been tested. replace the cap if there are readings which are not infinite. Inspect for corrosion excess on the boundaries and nail brushing to clean, and the cap to replace if there is an excess corrosion but some is normal. Check the rotor segment for excess misuse and replace the rotor when there is excess looseness. Inspect for shaft-to-bushing looseness by examining the housing for cracks and damage, putting the shaft into the housing to replace the whole housing assembly if the shaft wobbles. Finally, reinstall the engine cover.
