• Q: How to Replace Spark Plug Wires on 2003 Chevrolet Astro?

  A: Start the ignition cable replacement process by twisting each boot at the spark plugs a half turn and then removing it before using only the boot or an appropriate tool. After removing the ignition cable from its Distributor position perform a 1/2 turn boot twist then utilize either a tool or boot pull method to disconnect the seamless connection. When installing ignition cables start by connecting them to the Distributor while pushing sideways on each boot to prevent installation errors which could cause wire core erosion, engine misfire and internal damage. Set the ignition cable onto each Spark Plug for installation. Perform wire installation checks by pushing boot edges to the side while inspecting seat position and resetting loose connections to stop radio noise and ground shorting and crossfiring. When installing spark plugs or cables always apply fresh dielectric grease into the boot.
