how many lug nuts are on a 2005 trailblazer
There is no V-6 in any model of Trailblazer, it's an I-6, but the best and easiest way to answer your question is to visit http://www.trailvoy.com/ for your answer.
( 6 ) spark plugs
The 2005 Chevy Trailblazer has Coil-On-Plug ignition coils so there are 6 "coil packs". Each one is mounted on top of the spark plug.
The spark plugs are located along the top of the motor. They are covered by coil packs so you must remove the coil packs first to get to the spark plugs underneath. #1 is the front of the engine. If you are having misfire issues it may be the coil packs. We have a how to section with pictures at our enthusiasts website www.trailvoy.com
