• Q: How to Replace Spark Plug Wires on 2001 GMC Jimmy?

  A: First, remove each Spark Plug wire at each Spark Plug by twisting the boots 1/2 turn before you pull off the wire, only pull on the boot or use a tool made for this. Next, remove the Spark Plug wire from the Distributor and in the same exact 1/2 turn twist on the boot and pull only on the boot or use a tool only on the boot. When installing, it is necessary to ensure that the boots settle correctly by pushing in on the boots because improper seating may bring about a condition of wire core erosion, or one that causes the engine to misfire or one that causes damage from inside. Install the Spark Plug wires on the Distributor, then to the respective spark plugs. Check the integrity of installation of the wires by applying a sideward apressure to each boot to see seating, reseating any boot which is loose and ensure that wire routings are done to avoid the radio ignition noise, cross-firing and or shorting. Lastly, regular and apply new dielectric grease when Spark Plug wires or boot are attached on spark plugs.
