  Q: How to replace the Spark Plug Wires on Buick Terraza?

  A: To replace ignition cables (2, 4, and 6) from left side engine Spark Plugs twist each boot one-half turn counter-clockwise and pull only on the boot to prevent wire damage. After detaching the ignition cables from their retaining clips gently turn the engine to reach the back area. Afterward detach the ignition cables (1, 3 and 5) from right side engine spark plugs and their retaining clip and disconnect wires from Ignition Coils and the engine steel frame. When changing the ignition cables consumers need to move the conduit and retaining clips from the previous system. The installation process begins when you connect ignition cables 1, 3, and 5 to their corresponding ignition coils before linking them to their designated engine right side spark plugs. Finally, secure each wire with the retaining clip. Following engine rotation to its original position install the ignition cables (2, 4, and 6) to the ignition coils and from there to engine left side spark plugs until they lock into retaining clips.
