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:
If the boot to wire movement has occurred, the boot will give a false visual impression of being fully seated. Ensure that the boots have been properly assembled by pushing sideways on the installed boots. Failure to properly seat the terminal onto the spark plug will lead to wire core erosion and result in an engine misfire or crossfire condition, and possible internal damage to the engine.
- If corrosion, carbon tracking or arcing are indicated on a spark plug wire boot or on a terminal, replace the wire and the component connected to the wire. Install the spark plug wires at the distributor. Install the spark plug wire to each spark plug. See Fig 1 . Inspect the wires for proper installation. Push sideways on each boot in order to inspect the seating. Reinstall any loose boot.
- Wire routings must be kept intact during service and followed exactly when wires have been disconnected or when replacement of the wires is necessary. Failure to route the wires properly can lead to radio ignition noise and crossfiring of the plugs, or shorting of the leads to the ground. Any time the spark plug wires or boots are installed on the spark plugs, new dielectric grease needs to be applied inside the boot.
