Ignition Systems: Distributor: Inspection
WARNING: This page is about a different car, the 2003 GMC Safari and 2003 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Discoloration of the cap and some White colored build-up around the cap terminals is normal. Yellowing of the rotor cap, darkening and some carbon build-up under the rotor segment is normal. Replacement of the cap and the rotor is not necessary unless there is a driveability concern.
- Inspect the cap for excess build-up of corrosion on the terminals. Scrape clean the terminals. Replace the cap if the corrosion is excessive. Some build-up is normal. Inspect the rotor segment for excess wear. Replace the rotor if excess looseness in the rotor segment is present.
- Inspect the shaft for shaft-to-bushing looseness. Inspect the housing for cracks or damage. Rotate the shaft in the housing. Check if the shaft wobbles. Replace the housing assembly if any of the parts fail inspection.
