How do remove the spark plug wire harrness on the front of a 1990 buick century
Use a suitable spark plug wire tool to remove wire from spark plug being careful not to end up leaving the terminal from the wire on the plug. If the terminal is ripped away from the wire you will have to repair it by spreading open the crimps and reattach to wire and recrimp. Silicone spray works well to slide the wire further past the spark plug wire boot to make the repair.Always use die-electric or silicone grease on the inside of plugs wire boot before you attach to plug, it helps removal for next time and it seals the boot so spark dont leak from boot and makes a moisture barrier as well. Now to answer your question if the wires are in a loom holder you have to take the top part of the loom holder apart to get wires out of it . The loom holder usually just pops into slots on the bottom part of the loom holder. It shouldn't be too hard to figure out
